Fuzzy logic presents many potential applications for modelling and simulation.In particular, this paper analyses one of the most popular fuzzy techniques: Mamdani systems.Mamdani systems can look particularly appealing because they are designed to incorporate expert knowledge in form IF-THEN rules expressed natural language.While is an attractive feature simulating social other complex systems, its actual application important caveats.This studies use explore logical consequences a model...

We study population game dynamics under which each revising agent tests of his strategies a fixed number times, with play strategy being against newly drawn opponent, and chooses the whose total payoff was highest. In centipede game, these best experienced lead to cooperative play. When are tested once, at almost globally stable state is concentrated on last few nodes proportions agents playing largely independent length game. Testing many times leads cyclical

Fuzzy Logic is a framework particularly useful to formalise and deal with imprecise concepts statements expressed in natural language. This paper has three related aims. First, it aims provide short introduction the basics of within context social simulation. Secondly, presents well-documented NetLogo extension that facilitates use NetLogo. Finally, by providing concrete example, shows how researchers can build agent-based models which individual agents hold their own fuzzy rules, may also...

In populations subject to evolutionary processes, the assortment of players with different genes or strategies can have a large impact on players' payoffs and expected evolution each strategy in population. Here we consider generated by process partner choice known as selective assortment. Under assortment, looking for mate observe sample potential mates co-players, select one them interact with. This selection mechanism generate positive (preference using same strategy), negative strategy)....

EvoDyn-3s generates phase portraits of evolutionary dynamics, as well data for the analysis their equilibria. The considered dynamics are ordinary differential equations based on adaptive processes taking place in a population players who randomly and repeatedly matched couples to play 2-player symmetric normal-form game with three strategies. calculates rest points using exact arithmetic, represents them. It also provides eigenvalues Jacobian at isolated points, which useful evaluate local...

We consider a family of population game dynamics known as Best Experienced Payoff Dynamics. Under these dynamics, when agents are given the opportunity to revise their strategy, they test some possible strategies fixed number times. Crucially, each strategy is tested against new randomly drawn set opponents. The revising agent then chooses whose total payoff was highest in test, breaking ties according tie-breaking rule. Strict Nash equilibria rest points but need not be stable. provide...

This paper discusses a prominent way in which social simulations can contribute (and have contributed) to the advance of science; namely, by refuting some our incorrect beliefs about how real world works.More precisely, produce counter-examples that reveal something is wrong prevailing scientific assumption.Indeed, here we argue this role many well-known simulation models played, and it may be one main reasons why such become so popular.To test hypothesis, examine several popular literature...

The replicator-mutator dynamics is a set of differential equations frequently used in biological and socioeconomic contexts to model evolutionary processes subject mutation, error or experimentation. generalizes the widely replicator dynamics, which appears this framework as extreme case where replication perfectly precise. This paper studies influence strictly dominated strategies on location rest points at limit mutation terms become arbitrarily small. It can be proved that such for small...
