ABSTRACT
This chapter presents a collection of evolutionary game theoretic models that help to explore questions related to the strategy competition in nature. It provides some preliminaries about the swarm behavior and individual strategy in the gaming population. The chapter introduces the strategy competition among cooperation, defection, and speculation, hoping to shed light on how cooperation can be influenced by the introduction of speculation. It shows the role of the diversity of strategy choices of agents in the game playing. Individual heterogeneity is common in nature and social society of human. To characterize the interest conflicts between individuals and groups resulted by strategy competition, many theoretic models play a part in abstracting the essence of different social conflict scenarios. For example, the Prisoner's Dilemma game, Snowdrift game, Stag-Hunt game, Public Goods game, Rock–Paper–Scissors game, Public Goods Game with Threshold and are all often-used concrete game models.
