Co-operative navigation for target searching in a diffusion field

Discusses the problem of target searching by using co-operating agents in a simple chemical gradient field environment. Computer simulations in previous studies have demonstrated that the seemingly inefficient biased random walking strategy yields a better approach when searching for both static and moving targets in naturally unstable diffusion fields. The present study further generalises these findings to situations where the search efficiency can be improved by using two agents working in a co-ordinated manner. Comparisons between the efficiency of agents searching for stationary and moving targets in an independent manner and as a collaborating pair of agents are presented
