CBAG: state-of-the-art algorithm for Graph Burning

Official implementation of Centrality BAsed Genetic-algorithm (CBAG): state-of-the-art heuristic for solving the graph burning problem.

How to Use

1. Install the Boost Library.
2. Place your your dataset in ./Data directory. Refer to below section for more information.
3. Change the value of Path_To_Your_Boost_Here in Makefile file to the directory where your Boost library is installed in.
4. Assuming your file is named graph.csv and you wish to find a solution with burning length 10, run the following commands in your terminal:

$ make
$ ./CBAG graph.csv 10

Dataset

In order to use the algorithm for any desired graph:

1. Prepare the graph in a file with the following format.

   • First line contains the name of the graph with no spaces.
   • Second line contains four numbers: the number of nodes, the number of edges, whether the nodes are 1-indexed or not (0 if 0-indexed and 1 if 1-indexed), and whether the file contains edge weights or not (0 if not, 1 if yes) respectively.
   • The next edge number of lines each contains two or three numbers: each of the two nodes that are connected by that edge, and the weight of the edge optionally.

   For example, all of the three files below are denoting the K4 graph.

   Square-1
   4 6 0 0
   0 1
   0 2
   0 3
   1 2
   1 3
   2 3
   

   or

   Square-2
   4 6 1 0
   1 2
   1 3
   1 4
   2 3
   2 4
   3 4
   

   or even

   Square-3
   4 6 1 1
   1 2 23.4
   1 3 12.1
   1 4 24.4
   2 3 -34.3
   2 4 -12.3
   3 4 56.7
   

2. Place your file in the ./Data folder and run the algorithm. You may refer to ./Data folder in the repository for several examples.
