Recently, it has been shown that ants evacuate efficiently during a life- 3 and-death situation displaying an unselfish behavior (Boari et al., PlosOne 8:11, 4 2013, e81082). Here, we model this ant behavior and compare it with the more 5 expected selfish (human) behavior by considering different mixtures of evacuating 6 agentswithbothkindofbehaviors.Twounselfishbehaviorswerestudiedusingthe 7 socialforcemodelasphysicalbases.Fortheant-likebehavior,anoptimummixture 8 is found at 80 %. In the case of living-obstacle behavior, only 29 % is required to 9 achieve the minimum evacuation time. In general, the simulations with a mixture 10 of selfish and unselfish behavior show improvement in the evacuation time and 11 blockage probability of the exit.
