Foraging efficiency of ant colony is studied along the idea of strategy of errors. Strategy of errors is a seemingly-paradoxical group-tactics proposed by Deneubourg, meaning that errors of individual ants in following trail pheromone, rather, increase the efficiency of pheromone-mediated group foraging. In this paper, we first explain the basic idea of strategy of errors, thereafter, extend Deneubourg's original model to entrain more realistic processes. Through numerical calculations of the present model, we obtain two results: i) there are cases where non-uniform (element-dependent) distribution of the degree of errors in an ant colony enables the colony to make an optical foraging, ii) according to the variation of food-supplying environment, a transition of the optimal distribution of errors from the non-uniform distribution to the uniform distribution takes place. These results indicate that the idea of strategy of errors has a more scalability than that originally considered.

生産性向上には論理と規律の順守ばかりが求められてしまいがちだけど、実は広島大学の西森拓博士のグループによる『アリの集団採餌とエラー戦略』という研究から、エラー因子が長期的には組織の生産性を向上させる、とのこと。短期的な非効率が、長… https://t.co/QL1cJlWFpS
