Compiling the code

The following steps show how to compile and run the code to find atomic cliques in a Linux environment using a makefile (you can also run the code in Mac or Windows environment by configuring your IDE appropriately).

• "parameter.txt" file is used to configure testbed folder and type of solver
• "data" folder includes a subset of graph instances that are used in this study. Complete graph instances can be downloaded from Mendeley Data.

Steps to run the code to find atomic cliques solver in Linux environment:

1. Download or clone the repository to your machine.
2. Open the "Makefile" and set GUROBI_HOME to the directory of your Gurobi installation, e.g.: /opt/gurobi/9.5.1/linux64.
3. From the terminal, go to the folder containing "Makefile".
4. Type "make" and hit enter to compile.
5. Solver selection through "parameter.txt" file:

• If you would like to run Enhanced Formulation (EF) solver, set solver type =1.
• If you would like to run Edge Peeling (EP) + WB solver, set solver type =2. After Step 6, the code will run EP algorithm to generate auxiliary graphs as WB solver's input. Then run the WB solver on these auxiliary graphs.

6. Type "./main" to run the code.
