Na natureza, muitos animais lidam com o problema de encontrar parceiros, comida e abrigo. A estratégia de busca que orienta um organismo pode revelar aspectos importantes do seu comportamento, então, modelos são propostos para tratar deste problema. O passeio de Lévy é o modelo mais discutido, possui algum suporte empírico. Nosso objetivo foi comparar deslocamentos em linha reta com o passeio de Lévy e o movimento Browniano, considerando sobrevivência e probabilidade de recompensa. Os resultados mostram o deslocamento em linha reta com desempenho superior nos ambientes que criamos. Discutimos que a estratégia linha reta deveria ser considerada a mais provável estratégia de busca considerando os argumentos que dão suporte ao passeio de Lévy,...
