Contribution guidelines for this project

Dependencies

• Boost libraries >= 1.58;

• Modern C++ compiler supporting C++11;

  • This code was tested using GCC 5.2 and GCC 7.2 successfully. Clang 3.9 also compiles the code without problems, although changes in the parameters are necessary. A caveat is that to the date of this document was written, Clang does not use multiple threads of OpenMP, the technology behind the paralyzation of the decoding process.

• IBM ILOG CPLEX >= 12.5.0 for algorithm versions depending on LP relaxations (CALP, GALP). CPLEX libs can be disabled on the Makefile;

This package also includes a modified version of the brkgaAPI. The core functionality was kept, but changes in the API make the distributed version and the original version incompatible.

This package also includes (together brkgaAPI) a Mersenne Twister random number generator licensed under BSD-3.

Compiling and testing

First, you must set the proper paths to the "includes" and "libs" in your system. In the Makefile, go to the Section "Lib and include definitions" (line 84) and

• In "Cplex and Concert settings" subsection (line 93), set the path to your CPLEX installation.

Note that depending of the configuration of your system, other adjustments may be necessary.

To build the BRKGA, just use:

$ make all
