Learning the evolutionarily stable strategy

摘要: Abstract The possibility that animals learn a “developmentally stable strategy” (DSS) (Dawkins, 1980) is an alternative in biological game theory to the idea evolutionarily strategies (ESS) (Maynard Smith, 1972) are genetically determined. A learning rule defined as which assigns for every possible behaviour probability of displaying at each trial function previous payoffs. This report examines properties (ES) rule, i.e. which, when adopted by population, uninvadable mutant with different rule. DSS strategy used individuals ES With some simplifying assumptions, it shown ESS: ESSs. and other suggested approximation such relative payoff sum (RPS) states equal cumulative total payoffs game. Residual memory factor incorporated into RPS account prior expectations decay time. Both features adaptive. In simulations several frequency dependent independent games using response simulated was consistent predictions analysis has how ESSs may be achieved non-genetic means. described molecular terms utilizing synthesis, storage, degradation substance elicits behavioural response. If animals, should identify within neurons substances whose synthesis regulated stimuli initiate behaviours proportion their concentrations.
