infotaxis

noun

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.

Some literatures investigated the odor source localization by robots mimicking biologic behaviors, such as chemotaxis [<nowiki/>1] and anemotaxis [<nowiki/>2], or custom algorithms like fluxotaxis [<nowiki/>3] and infotaxis [<nowiki/>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.
