Swarm Intelligence project: Closest string problem

Usage

First, the C++ code needs to be compiled. This can be done in the terminal by executing (when being in the directory with the code):

g++ *.cpp -o CSP

his should result in a binary file called CSP. Some parameters can be passed to this file to influence the working of the program. These parameters are:

• --algo <string>: Algorithm to use. Can be mmas or acs. The default is mmas.
• --ants <int>: Number of ants to build every iteration. The default is 10.
• --alpha <float>: Alpha parameter (float). The default is 1.
• --beta <float>: Beta parameter (float). The default is 1.
• --rho <float>: Rho parameter (float). The default is 0.2.
• --iterations <int>: Maximum number of iterations to perform (integer). The default is 0 (disabled).
• --seed <int>: Number for the random seed generator.
• --ls: Use local search. If this parameter isn't given, local search is disabled.
• --exploitation <float>: Exploitation probability. The default is 0.9.
• --instance <string>: Path to the instance file

The analysis file, analysis.R, is an R script that can be called as such:

Rscript analysis.R
    /PATH/TO/RESULTS
    /PATH/TO/instances.opt

Some results of the analysis are printed and some are saved in the results directory that was passed to the program.
