Can Bio-Inspired Swarm Algorithms Scale to Modern Societal Problems

no code implementations20 May 2019 Darren M. Chitty, Elizabeth Wanner, Rakhi Parmar, Peter R. Lewis

Reducing the decision making required by ants by up to 90% results in markedly improved effectiveness and reduced runtimes for increasingly complex fleet optimisation problems.

Applying Partial-ACO to Large-scale Vehicle Fleet Optimisation

no code implementations16 Apr 2019 Darren M. Chitty, Elizabeth Wanner, Rakhi Parmar, Peter R. Lewis

Exact optimisation methods fail to scale to real commercial problem instances, thus meta-heuristics are more suitable.

Exploiting Tournament Selection for Efficient Parallel Genetic Programming

no code implementations19 Sep 2018 Darren M. Chitty

Genetic Programming (GP) is a computationally intensive technique which is naturally parallel in nature.

Applying ACO To Large Scale TSP Instances

no code implementations10 Sep 2017 Darren M. Chitty

However, ACO suffers from two issues; the first is that the technique has significant memory requirements for storing pheromone levels on edges between cities and second, the iterative probabilistic nature of choosing which city to visit next at every step is computationally expensive.
