AntColonyOptimization
A simple ACO implementation for TSP. MATLAB code.
This code was developed by Daniel Riofrio. It is based on the paper: Marco Dorigo et al. - Ant Colony Optimization.
This code is still work in progress. It has the main data structures and the basic idea of how to model a TSP problem, as well as an schedule problem (using the bipartite graph representation).
