LoversFlow2: An Individual-Based Evo-Eco Simulator on Sexual Dimorphism

Studies on evolution of sexual dimorphism are including useful suggestions to understand more deeply not only the ecological diversity in nature but also the gender diversity in human society. Here we present the design of our individual-based evo-eco simulator targeting an evolutionary process on sexual appearance, preference, and dimorphism, including sex-influenced traits. The simulator can manage some thousands of individual agents in continuous 2D space for birth, roaming, mating, reproduction, and death. It also has some auxiliary functions for monitoring and recording the evolutionary process for visualization and further statistical analysis. Accompanying with a detail of the mathematical model, some results are shown as example analysis concerning effects of distance bias and locality from view points of speciation and dimorphism.
