A dynamical system motivated by discrete physics is studied. Fuzzy dynamica
l systems are used to study fuzzy discrete replicator dynamics of hawk-dove
(HD) and prisoner's dilemma (PD) games. New solutions are obtained. Finall
y a preliminary study for fuzzy predator-prey model is studied and a new eq
uilibrium is found. (C) 2001 Elsevier Science Ltd. All rights reserved.
