multirow
This repository contains the source code for the papers on multi-row intersection cuts by Ricardo Fukasawa, Laurent Poirrier and Álinson S. Xavier. It also contains the instances, the raw outputs and the scripts that were used to generate the tables that appear in the papers.
Required tools and libraries
To produce the tables in the papers, the following tools and libraries were used. Different versions may produce slightly different outputs. Compiling the source code requires a modern C/C++ compiler, with support to C++11 features and OpenMP.
- GNU Make, version 3.81
- CMake, version 3.8
- GCC, the GNU Compiler Collection, version 6.3
- Ruby, version 1.9.3
- IBM® ILOG® CPLEX®, version 12.6
Downloading and compiling
git clone https://github.com/iSoron/multirow.git
cd multirow
git submodule update
mkdir build
cd build
cmake ..
make
If CMake cannot find CPLEX, it may be necessary to modify the file cmake/FindCPLEX.cmake.
