Standard ACO algorithm with an offline pheromone update is implemented to solve the ty48p asymmetric TSP problem.The Algorithms is implemented with the following parameters
Ant_count: Numbers of ants that will be exploring the population,
Iterations: Number of generations for which ants will be searching for solutions
PheromoneConstant: The constant used as a sufficient while calculating strength of pheromone applied by an individual ant based on its tour length
DecayConstant: Strength with which pheromone decays in a path
Alpha: Pheromone strength while finding the next city
Beta: Heuristic strength while finding the next city,
Initialization: How to initialize first population, either random or with a specific city
The best solution for ry48p as published in TSP site is 14422 though I managed to reach only 15473. But considering the stochastic nature of algorithms and provided more computational space, this algorithm
