This repository contains the C++ source codes of the machine learning-based column generation (MLCG) method for solving the vertex coloring problem. ------------------ Install & compile: ------------------ packages required: 1) cmake/3.15.4 or above; 2) gcc-8.1.0 or above; 3) gurobi/9.0.1; and 4) igraph-0.8.5. compile: 1) move to the build directory: 'cd build' 2) run cmake: 'cmake -DIGRAPH_ROOT_DIR=</path/to/igraph> ..'. The path to your IGRAPH installation must be such that '</path/to/igraph>/include/igraph/igraph.h' exists. 3) run makefile: 'make'. ------ Usage: ------ Usage: ./GCP datafile_ID datafile_ID : the index of the graph to solve, an integer from 1 to 1000. --------- Examples: --------- ./GCP 101 : solve the graph g0101.col using the MLCG method. ----------- References: ----------- Sun Y, Ernst A, Li X, and Weiner, J.
