Optimal Search Strategies under Finite Resource Constraints
Hugues Meyer
Improving target search is a challenge faced by many natural and artificial agents, often requiring the use of energetic or material resources. These inputs may be supplied by an e…
Optimal Search Strategies under Finite Resource Constraints: The Role of Environmental Memory and Directional Information in Informed and Blind Protocols
Hugues Meyer
Improving the efficiency of a stochastic search often requires to provide the searching agent with resources that modify its dynamics and help it explore space more quickly. Althou…
Weak-Memory Dynamics in Discrete Time
Hugues Meyer, Kay Brandner
Discrete dynamics arise naturally in systems with broken temporal translation symmetry and are typically described by first-order recurrence relations representing classical or qua…
Collective chemotactic search
Adam Wysocki, Hugues Meyer, Heiko Rieger
We investigate collective search by self-propelled agents that are repelled by their own chemically produced trails, a minimal mechanism that simultaneously generates indirect inte…
Optimal number of agents in a collective search, and when to launch them
Hugues Meyer, Heiko Rieger
Search processes often involve multiple agents that collectively search a randomly located target. While increasing the number of agents usually decreases the time at which the fir…
Non-Markovian and Collective Search Strategies
Hugues Meyer, Heiko Rieger
Agents searching for a target can improve their efficiency by memorizing where they have already been searching or by cooperating with other searchers and using strategies that ben…
