Definitions

Any searching strategy in which there is sparse information, especially a strategy used by biological organisms to zigzag towards the source of an odour based on sporadic clues.

uncountable

“2006–7, Massimo Vergassola et al., "‘Infotaxis’ as a strategy for searching without gradients", in Nature, volume 445, pages 406–409 (2007 January 25)”

“Some literatures investigated the odor source localization by robots mimicking biologic behaviors, such as chemotaxis [1] and anemotaxis [2], or custom algorithms like⟳ fluxotaxis [3] and infotaxis [4]. The multi-robot system has more advantages than single robot in odor source localization. First, the expected search⟳ time can be decreased. Second, the multi-robot system does not easily fall⟳ into local maxima.”

“In the framework of the so-called infotaxis algorithm any search⟳ process⟳ can be thought of as acquisition of information on source location. Thus information plays a role similar to concentration in chemotaxis. Then the infotaxis strategy locally maximizes the expected rate of information gain⟳.”

“In a recent paper, Vergassola et al. demonstrated that infotaxis, which is motion based on expected information gain⟳, can be a more effective search⟳ strategy when the source signal is weak than conventional methods such as moving along the gradient of a chemical concentration [2]. The infotaxis algorithm combines the two competing goals of exploration of possible search⟳ moves and exploitation of received signals to guide⟳ the searcher in the direction with the highest probability of finding the source [3].”
