}This repository contains 5 folders, each for one variant of the branch-and-Benders-cut algorithm presented in the paper as follows.
- BBC1: Multicut reformulation
- BBC2: Multicut reformulation with penalty reformulation
- BBC3: Multicut reformulation with Pareto-optimal cuts
- BBC4: Multicut reformulation with supervalid and valid inequalities
- BBC5: Multicut reformulation with all the acceleration techniques
Please note that for using the codes in Visual Studio, you should change the time function to clock(). The current time fucntion gettimeofday(&stop, NULL) is for Linux.
To use the code, you need CPLEX 22.1.0. To use other versions of CPLEX, modify the Makefile and def.h with your CPLEX version.
To run e.g. BBC2 in Linux:
make
./BBCPenaltymulti Input.txt
All detailed results are available in the Results folder.
