+Intersection Cuts for Single Row Relaxations
+============================================
+
+This package contains the source code for the wedge cut generator
+described in the paper **Intersection Cuts for Single Row Relaxations**,
+by Ricardo Fukasawa, Laurent Poirrier and Álinson S. Xavier.
+
+
+Required Tools and Libraries
+----------------------------
+
+To produce the tables in the paper, the following tools and libraries were
+used. Different versions may produce slightly different outputs.
+
+- GNU Make, version 3.81
+- CMake, version 3.5.1
+- GCC, the GNU Compiler Collection, version 4.8.4
+- GMP, the GNU Multiple Precision Arithmetic Library, version 6.1.0
+- Ruby, version 1.9.3
+- IBM® ILOG® CPLEX®, version 12.6.2
+
+
+Build instructions
+------------------
+
+1. Make sure that CPLEX is correctly installed in your system and that
+the paths in `cmake/FindCPLEX.cmake` point to the correct install location.
+2. Navigate to the folder `build` and run `cmake ..` followed by `make`
+3. After the compilation is finished, two binaries will be generated inside
+ the `build` folder: a library `libonerow.a`, which can be used
+ independently to generate wedge cuts, and an executable
+ `onerow-benchmark.run`, which can be used to run the experiments presented
+ in the paper.
+
+Running the experiments
+-----------------------
+
+1. Navigate to the folder `onerow/benchmark`.
+2. To run the computational experiments for all instances, run:
+
+        ./make
+
+3. To run the computational experiments for a particular instance, give the
+   filename as argument. For example:
+
+        ./make instances/30n20b8.pre.done
+
+4. To run the computational experiments for multiple instances in parallel,
+   the option -j can be used. For example, to run four instances simultaneously,
+   run:
+
+        ./make -j4
+
+5. Two files will be generated per instance, inside the folder `out`. One file
+   contains the log, which was printed to the terminal during the execution,
+   while the other file (ending in .yaml), contains the experiment results.
+
+
+Generating the tables
+---------------------
+
+1. Navigate to the folder `onerow/benchmark`.
+2. Run the computational experiments, as describe above.
+2. After the experiments are finished, run `./generate_tables`.
+3. Extended versions of Table 1 and 2 will be printed, in CSV format. A
+   copy will also be saved in `onerow/benchmark/tables`.
+
+Heuristics
+----------
+
+Many parameters for the cut generator can be specified by modifying the
+file `params.hpp`, located in `onerow/library/include/onerow/`.
+For example, the three heuristics described in the paper can be achieved
+by setting:
+
+    MAX_CUT_DEPTH = 5
+    MAX_R1_RAYS   = 100
+    MAX_GOOD_ROWS = 100
+
+After changing these parameters, it will be necessary to recompile the
+project.
