3. Multidimensional Knapsack

-
-

3.1. Problem definition

-

Given a set of \(n\) items and \(m\) types of resources (also called knapsacks), the problem is to find a subset of items that maximizes profit without consuming more resources than it is available. More precisely, the problem is:

-
-\[\begin{split}\begin{align*} - \text{maximize} - & \sum_{j=1}^n p_j x_j - \\ - \text{subject to} - & \sum_{j=1}^n w_{ij} x_j \leq b_i - & \forall i=1,\ldots,m \\ - & x_j \in \{0,1\} - & \forall j=1,\ldots,n -\end{align*}\end{split}\]
-
-
-

3.2. Random instance generator

-

The class MultiKnapsackGenerator can be used to generate random instances of this problem. The number of items \(n\) and knapsacks \(m\) are sampled from the user-provided probability distributions n and m. The weights \(w_{ij}\) are sampled independently from the provided distribution w. The capacity of knapsack \(i\) is set to

-
-\[b_i = \alpha_i \sum_{j=1}^n w_{ij}\]
-

where \(\alpha_i\), the tightness ratio, is sampled from the provided probability distribution alpha. To make the instances more challenging, the costs of the items are linearly correlated to their average weights. More specifically, the price of each item \(j\) is set to:

-
-\[p_j = \sum_{i=1}^m \frac{w_{ij}}{m} + K u_j,\]
-

where \(K\), the correlation coefficient, and \(u_j\), the correlation multiplier, are sampled from the provided probability distributions K and u.

-

If fix_w=True is provided, then \(w_{ij}\) are kept the same in all generated instances. This also implies that \(n\) and \(m\) are kept fixed. Although the prices and capacities are derived from \(w_{ij}\), as long as u and K are not constants, the generated instances will still not be completely identical.

-

If a probability distribution w_jitter is provided, then item weights will be set to \(w_{ij} \gamma_{ij}\) where \(\gamma_{ij}\) is sampled from w_jitter. When combined with fix_w=True, this argument may be used to generate instances where the weight of each item is roughly the same, but not exactly identical, across all instances. The prices of the items and the capacities of the knapsacks will be calculated as above, but using these perturbed weights instead.

-

By default, all generated prices, weights and capacities are rounded to the nearest integer number. If round=False is provided, this rounding will be disabled.

1. Preliminaries

-
-

1.1. Benchmark challenges

-

When evaluating the performance of a conventional MIP solver, benchmark sets, such as MIPLIB and TSPLIB, are typically used. The performance of newly proposed solvers or solution techniques are typically measured as the average (or total) running time the solver takes to solve the entire benchmark set. For Learning-Enhanced MIP solvers, it is also necessary to specify what instances should the solver be trained on (the training instances) before solving the actual set of instances we are -interested in (the test instances). If the training instances are very similar to the test instances, we would expect a Learning-Enhanced Solver to present stronger perfomance benefits.

-

In MIPLearn, each optimization problem comes with a set of benchmark challenges, which specify how should the training and test instances be generated. The first challenges are typically easier, in the sense that training and test instances are very similar. Later challenges gradually make the sets more distinct, and therefore harder to learn from.

-
-
-

1.2. Baseline results

-

To illustrate the performance of LearningSolver, and to set a baseline for newly proposed techniques, we present in this page, for each benchmark challenge, a small set of computational results measuring the solution speed of the solver and the solution quality with default parameters. For more detailed computational studies, see references. We compare three solvers:

-
    -

  • baseline: Gurobi 9.1 with default settings (a conventional state-of-the-art MIP solver)

    • -

  • ml-exact: LearningSolver with default settings, using Gurobi 9.0 as internal MIP solver

    • -

  • ml-heuristic: Same as above, but with mode="heuristic"

    • -
-

All experiments presented here were performed on a Linux server (Ubuntu Linux 18.04 LTS) with Intel Xeon Gold 6230s (2 processors, 40 cores, 80 threads) and 256 GB RAM (DDR4, 2933 MHz). All solvers were restricted to use 4 threads, with no time limits, and 10 instances were solved simultaneously at a time.

2. Maximum Weight Stable Set

-
-

2.1. Problem definition

-

Given a simple undirected graph \(G=(V,E)\) and weights \(w \in \mathbb{R}^V\), the problem is to find a stable set \(S \subseteq V\) that maximizes $ \sum_{v \in `V} w_v$. We recall that a subset :math:`S \subseteq V is a stable set if no two vertices of \(S\) are adjacent. This is one of Karp’s 21 NP-complete problems.

-
-
-

2.2. Random instance generator

-

The class MaxWeightStableSetGenerator can be used to generate random instances of this problem, with user-specified probability distributions. When the constructor parameter fix_graph=True is provided, one random Erdős-Rényi graph \(G_{n,p}\) is generated during the constructor, where \(n\) and \(p\) are sampled from user-provided probability distributions n and p. To generate each instance, the generator independently samples each \(w_v\) from the user-provided -probability distribution w. When fix_graph=False, a new random graph is generated for each instance, while the remaining parameters are sampled in the same way.

-
-
-

2.3. Challenge A

-
    -

  • Fixed random Erdős-Rényi graph \(G_{n,p}\) with \(n=200\) and \(p=5\%\)

    • -

  • Random vertex weights \(w_v \sim U(100, 150)\)

4. Traveling Salesman

-
-

4.1. Problem definition

-

Given a list of cities and the distance between each pair of cities, the problem asks for the shortest route starting at the first city, visiting each other city exactly once, then returning to the first city. This problem is a generalization of the Hamiltonian path problem, one of Karp’s 21 NP-complete problems.

-
-
-

4.2. Random problem generator

-

The class TravelingSalesmanGenerator can be used to generate random instances of this problem. Initially, the generator creates \(n\) cities \((x_1,y_1),\ldots,(x_n,y_n) \in \mathbb{R}^2\), where \(n, x_i\) and \(y_i\) are sampled independently from the provided probability distributions n, x and y. For each pair of cities \((i,j)\), the distance \(d_{i,j}\) between them is set to:

-
-\[d_{i,j} = \gamma_{i,j} \sqrt{(x_i-x_j)^2 + (y_i - y_j)^2}\]
-

where \(\gamma_{i,j}\) is sampled from the distribution gamma.

-

If fix_cities=True is provided, the list of cities is kept the same for all generated instances. The \(gamma\) values, and therefore also the distances, are still different.

-

By default, all distances \(d_{i,j}\) are rounded to the nearest integer. If round=False is provided, this rounding will be disabled.

-
-
-

4.3. Challenge A

MIPLearn

-

MIPLearn is an extensible framework for solving discrete optimization problems using a combination of Mixed-Integer Linear Programming (MIP) and Machine Learning (ML). The framework uses ML methods to automatically identify patterns in previously solved instances of the problem, then uses these patterns to accelerate the performance of conventional state-of-the-art MIP solvers (such as CPLEX, Gurobi or XPRESS).

-

Unlike pure ML methods, MIPLearn is not only able to find high-quality solutions to discrete optimization problems, but it can also prove the optimality and feasibility of these solutions. -Unlike conventional MIP solvers, MIPLearn can take full advantage of very specific observations that happen to be true in a particular family of instances (such as the observation that a particular constraint is typically redundant, or that a particular variable typically assumes a certain value).

1. Getting started with MIPLearn

-
-

1.1. Introduction

-

MIPLearn is an open source framework that uses machine learning (ML) to accelerate the performance of both commercial and open source mixed-integer programming solvers (e.g. Gurobi, CPLEX, XPRESS, Cbc or SCIP). In this tutorial, we will:

-
    -

  1. Install the Julia/JuMP version of MIPLearn

    2. -

  2. Model a simple optimization problem using JuMP

    3. -

  3. Generate training data and train the ML models

    4. -

  4. Use the ML models together with SCIP to solve new instances

    5. -
-
-

Note

-

In this tutorial, we use SCIP because it is more widely available than commercial MIP solvers. However, all the steps below should work for Gurobi, CPLEX or XPRESS, as long as you have a license for these solvers. The performance impact of MIPLearn may also change for different solvers.

-
-
-

Warning

-

MIPLearn is still in early development stage. If run into any bugs or issues, please submit a bug report in our GitHub repository. Comments, suggestions and pull requests are also very welcome!

-
-
-
-

1.2. Installation

-

MIPLearn is available in two versions:

-
    -

  • Python version, compatible with the Pyomo modeling language,

    • -

  • Julia version, compatible with the JuMP modeling language.

    • -
-

In this tutorial, we will demonstrate how to use and install the Julia/JuMP version of the package. The first step is to install the Julia programming language in your computer. See the official instructions for more details. Note that MIPLearn was developed and tested with Julia 1.6, and may not be compatible with newer versions of the language. After Julia is installed, launch its console and run the following commands to download and install the package:

-
-

-
-
-
-using Pkg
-Pkg.add(PackageSpec(url="https://github.com/ANL-CEEESA/MIPLearn.jl.git"))

In addition to MIPLearn itself, we will also install a few other packages that are required for this tutorial:

-
    -

  • SCIP, one of the fastest non-commercial MIP solvers currently available

    • -

  • JuMP, an open source modeling language for Julia

    • -

  • Distributions.jl, a statistics package that we will use to generate random inputs

    • -

  • Glob.jl, a package that retrieves all files in a directory matching a certain pattern

    • -

Note

-

In the code above, we install specific version of all packages to ensure that this tutorial keeps running in the future, even when newer (and possibly incompatible) versions of the packages are released. This is usually a recommended practice for all Julia projects.

-
-
-
-

1.3. Modeling a simple optimization problem

-

To illustrate how can MIPLearn be used, we will model and solve a small optimization problem related to power systems optimization. The problem we discuss below is a simplification of the unit commitment problem, a practical optimization problem solved daily by electric grid operators around the world.

-

Suppose that you work at a utility company, and that it is your job to decide which electrical generators should be online at a certain hour of the day, as well as how much power should each generator produce. More specifically, assume that your company owns \(n\) generators, denoted by \(g_1, \ldots, g_n\). Each generator can either be online or offline. An online generator \(g_i\) can produce between \(p^\text{min}_i\) to \(p^\text{max}_i\) megawatts of power, and it costs -your company \(c^\text{fix}_i + c^\text{var}_i y_i\), where \(y_i\) is the amount of power produced. An offline generator produces nothing and costs nothing. You also know that the total amount of power to be produced needs to be exactly equal to the total demand \(d\) (in megawatts). To minimize the costs to your company, which generators should be online, and how much power should they produce?

-

This simple problem can be modeled as a mixed-integer linear optimization problem as follows. For each generator \(g_i\), let \(x_i \in \{0,1\}\) be a decision variable indicating whether \(g_i\) is online, and let \(y_i \geq 0\) be a decision variable indicating how much power does \(g_i\) produce. The problem is then given by:

-
-\[\begin{split}\begin{align} -\text{minimize } \quad & \sum_{i=1}^n \left( c^\text{fix}_i x_i + c^\text{var}_i y_i \right) \\ -\text{subject to } \quad & y_i \leq p^\text{max}_i x_i & i=1,\ldots,n \\ -& y_i \geq p^\text{min}_i x_i & i=1,\ldots,n \\ -& \sum_{i=1}^n y_i = d \\ -& x_i \in \{0,1\} & i=1,\ldots,n \\ -& y_i \geq 0 & i=1,\ldots,n -\end{align}\end{split}\]
-
-

Note

-

We use a simplified version of the unit commitment problem in this tutorial just to make it easier to follow. MIPLearn can also handle realistic, large-scale versions of this problem. See benchmarks for more details.

-
-

Next, let us convert this abstract mathematical formulation into a concrete optimization model, using Julia and JuMP. We start by defining a data structure that holds all the input data.

-
-
[3]:
-
-
-
-Base.@kwdef struct UnitCommitmentData
-    demand::Float64
-    pmin::Vector{Float64}
-    pmax::Vector{Float64}
-    cfix::Vector{Float64}
-    cvar::Vector{Float64}
-end;
-
-
-
-

Next, we create a function that converts this data structure into a concrete JuMP model. For more details on the JuMP syntax, see the official JuMP documentation.

-
-
[4]:
-
-
-
-using JuMP
-
-function build_uc_model(data::UnitCommitmentData)::Model
-    model = Model()
-    n = length(data.pmin)
-    @variable(model, x[1:n], Bin)
-    @variable(model, y[1:n] >= 0)
-    @objective(
-        model,
-        Min,
-        sum(
-            data.cfix[i] * x[i] +
-            data.cvar[i] * y[i]
-            for i in 1:n
-        )
-    )
-    @constraint(model, eq_max_power[i in 1:n], y[i] <= data.pmax[i] * x[i])
-    @constraint(model, eq_min_power[i in 1:n], y[i] >= data.pmin[i] * x[i])
-    @constraint(model, eq_demand, sum(y[i] for i in 1:n) == data.demand)
-    return model
-end;
-
-
-
-

At this point, we can already use JuMP and any mixed-integer linear programming solver to find optimal solutions to any instance of this problem. To illustrate this, let us solve a small instance with three generators, using SCIP:

-
-
[5]:
-
-
-
-using SCIP
-
-model = build_uc_model(
-    UnitCommitmentData(
-        demand = 100.0,
-        pmin = [10, 20, 30],
-        pmax = [50, 60, 70],
-        cfix = [700, 600, 500],
-        cvar = [1.5, 2.0, 2.5],
-    )
-)
-
-scip = optimizer_with_attributes(SCIP.Optimizer, "limits/gap" => 1e-4)
-set_optimizer(model, scip)
-set_silent(model)
-optimize!(model)
-
-println("obj = ", objective_value(model))
-println("  x = ", round.(value.(model[:x])))
-println("  y = ", round.(value.(model[:y]), digits=2));
-
-
-
-
-
-
-
-
-obj = 1320.0
-  x = [0.0, 1.0, 1.0]
-  y = [0.0, 60.0, 40.0]
-
-
-

Running the code above, we found that the optimal solution for our small problem instance costs $1320. It is achieve by keeping generators 2 and 3 online and producing, respectively, 60 MW and 40 MW of power.

-
-
-

1.4. Generating training data

-

Although SCIP could solve the small example above in a fraction of a second, it gets slower for larger and more complex versions of the problem. If this is a problem that needs to be solved frequently, as it is often the case in practice, it could make sense to spend some time upfront generating a trained version of SCIP, which can solve new instances (similar to the ones it was trained on) faster.

-

In the following, we will use MIPLearn to train machine learning models that can be used to accelerate SCIP’s performance on a particular set of instances. More specifically, MIPLearn will train a model that is able to predict the optimal solution for instances that follow a given probability distribution, then it will provide this predicted solution to SCIP as a warm start.

-

Before we can train the model, we need to collect training data by solving a large number of instances. In real-world situations, we may construct these training instances based on historical data. In this tutorial, we will construct them using a random instance generator:

-
-
[6]:
-
-
-
-using Distributions
-using Random
-
-function random_uc_data(; samples::Int, n::Int, seed=42)
-    Random.seed!(seed)
-    pmin = rand(Uniform(100, 500.0), n)
-    pmax = pmin .* rand(Uniform(2.0, 2.5), n)
-    cfix = pmin .* rand(Uniform(100.0, 125.0), n)
-    cvar = rand(Uniform(1.25, 1.5), n)
-    return [
-        UnitCommitmentData(;
-            pmin,
-            pmax,
-            cfix,
-            cvar,
-            demand = sum(pmax) * rand(Uniform(0.5, 0.75)),
-        )
-        for i in 1:samples
-    ]
-end;
-
-
-
-

In this example, for simplicity, only the demands change from one instance to the next. We could also have made the prices and the production limits random. The more randomization we have in the training data, however, the more challenging it is for the machine learning models to learn solution patterns.

-

Now we generate 100 instances of this problem, each one with 1,000 generators. We will use the first 90 instances for training, and the remaining 10 instances to evaluate SCIP’s performance.

-
-
[7]:
-
-
-
-data = random_uc_data(samples=100, n=1000);
-train_data = data[1:90]
-test_data = data[91:100];
-
-
-
-

Next, we write these data structures to individual files. MIPLearn uses files during the training process because, for large-scale optimization problems, it is often impractical to hold the entire training data, as well as the concrete JuMP models, in memory. Files also make it much easier to solve multiple instances simultaneously, potentially even on multiple machines. We will cover parallel and distributed computing in a future tutorial.

-

The code below generates the files uc/train/000001.jld2, uc/train/000002.jld2, etc., which contain the input data in JLD2 format.

-
-
[8]:
-
-
-
-using MIPLearn
-MIPLearn.save(data[1:90], "uc/train/")
-MIPLearn.save(data[91:100], "uc/test/")
-
-using Glob
-train_files = glob("uc/train/*.jld2")
-test_files = glob("uc/test/*.jld2");
-
-
-
-

Finally, we use MIPLearn.LearningSolver and MIPLearn.solve! to solve all the training instances. LearningSolver is the main component provided by MIPLearn, which integrates MIP solvers and ML. The solve! function can be used to solve either one or multiple instances, and requires: (i) the list of files containing the training data; and (ii) the function that converts the data structure into a concrete JuMP model:

-
-
[9]:
-
-
-
-using Glob
-solver = LearningSolver(scip)
-@time solve!(solver, train_files, build_uc_model);
-
-
-
-
-
-
-
-
-103.808547 seconds (93.52 M allocations: 3.604 GiB, 1.19% gc time, 0.52% compilation time)
-
-
-
-
-
-
-
-WARNING: Dual bound 1.98665e+07 is larger than the objective of the primal solution 1.98665e+07. The solution might not be optimal.
-
-
-

The macro @time shows us how long did the code take to run. We can see that SCIP was able to solve all training instances in about 2 minutes. The solutions, and other useful training data, are stored by MIPLearn in .h5 files, stored side-by-side with the original .jld2 files.

-
-
-

1.5. Solving new instances

-

With training data in hand, we can now fit the ML models using MIPLearn.fit!, then solve the test instances with MIPLearn.solve!, as shown below:

-
-
[10]:
-
-
-
-solver_ml = LearningSolver(scip)
-fit!(solver_ml, train_files, build_uc_model)
-@time solve!(solver_ml, test_files, build_uc_model);
-
-
-
-
-
-
-
-
-  5.951264 seconds (9.33 M allocations: 334.657 MiB, 1.51% gc time)
-
-
-

The trained MIP solver was able to solve all test instances in about 6 seconds. To see that ML is being helpful here, let us repeat the code above, but remove the fit! line:

-
-
[11]:
-
-
-
-solver_baseline = LearningSolver(scip)
-@time solve!(solver_baseline, test_files, build_uc_model);
-
-
-
-
-
-
-
-
- 10.390325 seconds (8.17 M allocations: 278.042 MiB, 0.89% gc time)
-
-
-

Without the help of the ML models, SCIP took around 10 seconds to solve the same test instances.

-
-

Note

-

Note that is is not necessary to specify what ML models to use. MIPLearn, by default, will try a number of classical ML models and will choose the one that performs the best, based on k-fold cross validation. MIPLearn is also able to automatically collect features based on the MIP formulation of the problem and the solution to the LP relaxation, among other things, so it does not require handcrafted features. If you do want to customize the models and features, however, that is also possible, as -we will see in a later tutorial.

-
-
-
-

1.6. Understanding the acceleration

-

Let us go a bit deeper and try to understand how exactly did MIPLearn accelerate SCIP’s performance. First, we are going to solve one of the test instances again, using the trained solver, but this time using the tee=true parameter, so that we can see SCIP’s log:

-
-
[12]:
-
-
-
-solve!(solver_ml, test_files[1], build_uc_model, tee=true);
-
-
-
-
-
-

The log above is quite complicated if you have never seen it before, but the important line is the one starting with feasible solution found [...] objective value 1.705169e+07. This line indicates that MIPLearn was able to construct a warm start with value 1.705169e+07. Using this warm start, SCIP then used the branch-and-cut method to either prove its optimality or to find an even better solution. Very quickly, however, SCIP proved that the solution produced by MIPLearn was indeed -optimal. It was able to do this without generating a single cutting plane or running any other heuristics; it could tell the optimality by the root LP relaxation alone, which was very fast.

In this log file, notice how the previous line about warm starts is missing. Since no warm starts were provided, SCIP had to find an initial solution using its own internal heuristics, which are not specifically tailored for this problem. The initial solution found by SCIP’s heuristics has value 2.335200e+07, which is significantly worse than the one constructed by MIPLearn. SCIP then proceeded to improve this solution, by generating cutting planes and repeatedly running additional primal -heuristics. In the end, it was able to find the optimal solution, as expected, but it took longer.

-

In summary, MIPLearn accelerated the solution process by constructing a high-quality initial solution. In the following tutorials, we will see other strategies that MIPLearn can use to accelerate MIP performance, besides warm starts.

-
-
-

1.7. Accessing the solution

-

In the example above, we used MIPLearn.solve! together with data files to solve both the training and the test instances. The solutions were saved to a .h5 files in the train/test folders, and could be retrieved by reading theses files, but that is not very convenient. In this section we will use an easier method.

-

We can use the function MIPLearn.load! to obtain a regular JuMP model:

-
-
[14]:
-
-
-
-model = MIPLearn.load("uc/test/000001.jld2", build_uc_model)
-
-
-
-
-
[14]:
-
-
-
-
-A JuMP Model
-Minimization problem with:
-Variables: 2000
-Objective function type: AffExpr
-`AffExpr`-in-`MathOptInterface.EqualTo{Float64}`: 1 constraint
-`AffExpr`-in-`MathOptInterface.GreaterThan{Float64}`: 1000 constraints
-`AffExpr`-in-`MathOptInterface.LessThan{Float64}`: 1000 constraints

-Model mode: AUTOMATIC
-CachingOptimizer state: NO_OPTIMIZER
-Solver name: No optimizer attached.
-Names registered in the model: eq_demand, eq_max_power, eq_min_power, x, y
-
-
-

We can then solve this model as before, with MIPLearn.solve!:

-
-
[15]:
-
-
-
-solve!(solver_ml, model)
-println("obj = ", objective_value(model))
-println("  x = ", round.(value.(model[:x][1:10])))
-println("  y = ", round.(value.(model[:y][1:10]), digits=2))
-
-
-
-
-
-
-
-
-obj = 1.7051217395548128e7

MIPLearn uses ML methods to automatically identify patterns in previously solved instances of the problem, then uses these patterns to accelerate the performance of conventional state-of-the-art MIP solvers such as CPLEX, Gurobi or XPRESS. -Unlike pure ML methods, MIPLearn is not only able to find high-quality solutions to discrete optimization problems, but it can also prove the optimality and feasibility of these solutions. Unlike conventional MIP solvers, MIPLearn can take full advantage of very specific observations that happen to be true in a particular family of instances (such as the observation that a particular constraint is typically redundant, or that a particular variable typically assumes a certain value). For certain classes of problems, this approach has been shown to provide significant performance benefits (see benchmarks and references). +Unlike pure ML methods, MIPLearn is not only able to find high-quality solutions to discrete optimization problems, but it can also prove the optimality and feasibility of these solutions.

    MIPLearn

    MIPLearn is an extensible framework for solving discrete optimization problems using a combination of Mixed-Integer Linear Programming (MIP) and Machine Learning (ML). MIPLearn uses ML methods to automatically identify patterns in previously solved instances of the problem, then uses these patterns to accelerate the performance of conventional state-of-the-art MIP solvers such as CPLEX, Gurobi or XPRESS.

    -

    Unlike pure ML methods, MIPLearn is not only able to find high-quality solutions to discrete optimization problems, but it can also prove the optimality and feasibility of these solutions. Unlike conventional MIP solvers, MIPLearn can take full advantage of very specific observations that happen to be true in a particular family of instances (such as the observation that a particular constraint is typically redundant, or that a particular variable typically assumes a certain value). For certain classes of problems, this approach has been shown to provide significant performance benefits (see benchmarks and references).
