Abstract: Standard ACO implementations use a roulette wheel to allow ants to make path decisions at each node of the topology which works well for problems of smaller dimensionality, but breaks down when higher numbers of variables are considered. Such problems are becoming commonplace in biology and particularly in genomics where thousands of variables are considered in parallel. In this paper, a tournament-based ACO approach is proposed that is shown to outperform the roulette wheel-based approach for all problems of higher dimensionality in terms of the performance of the final solutions and execution time on problems taken from the literature.
