On the evolutionary stability of partial migration

Journal of Theoretical Biology, 2013
The evolution of partial migration in birds is typically assumed to be the result of an optimization process. The fitness rewards for individuals choosing to migrate are balanced against the rewards of remaining in the breeding area all year around.

Evolutionary stability in a reputational model of bargaining [PDF]

Games and Economic Behavior, 2001
In this research work the authors endogenize departures from rationality on the foundations of the processes concerning the evolutionary selections, using for appropriate interpretations some adequate kinds of probabilities, in the environments with unobservable players types.

Stability in an evolutionary game

Theoretical Population Biology, 1984
Consider a population of plants or animals, ''players'' whose phenotype (or strategy) can be represented by a real number n. If only two strategies \(n_ 0\), \(n_ 1\) are in use, denote for \(i=0,1\) the fraction of players of type \(n_ i\) at time t by \(P_ i(t)\), and let the population evolve according to the law \[ (*)\quad P_ i(t+1)\sim P_ i(t ...

Evolutionary stability in Lotka–Volterra systems

Journal of Theoretical Biology, 2003
The Lotka-Volterra model of population ecology, which assumes all individuals in each species behave identically, is combined with the behavioral evolution model of evolutionary game theory. In the resultant monomorphic situation, conditions for the stability of the resident Lotka-Volterra system, when perturbed by a mutant phenotype in each species ...

Crossover and Evolutionary Stability in the Prisoner's Dilemma

Evolutionary Computation, 2007
We examine the role played by crossover in a series of genetic algorithm-based evolutionary simulations of the iterated prisoner's dilemma. The simulations are characterized by extended periods of stability, during which evolutionarily meta-stable strategies remain more or less fixed in the population, interrupted by transient, unstable episodes ...

The Evolutionary Stability of Cooperation

American Political Science Review, 1997
Is cooperation without central authority stable? If so, how robust is it? Despite what might be the conventional wisdom,The Evolution of Cooperationdid not solve this problem deductively. In fact, results obtained later by others seem to have contradicted the book's main message.

Evolutionary stability of developmental commitment

BioSystems
Evolution of unicellular to multicellular organisms must resolve conflicts in reproductive interests between individual cells and the group. The social amoeba Dictyostelium discoideum is a soil-living eukaryote with facultative sociality. While cells grow in the presence of nutrients, cells aggregate under starvation to form fruiting bodies containing ...

ON THE EVOLUTIONARY STABILITY OF "TOUGH" BARGAINING BEHAVIOR

International Game Theory Review, 2003
This paper investigates whether "tough" bargaining behavior, which gives rise to inefficiency, can be evolutionarily stable. We show that in a two-stage Nash Demand Game such behavior survives. Indeed, almost all the surplus may be wasted. We also study the Ultimatum Game.

Evolutionary and continuous stability

Journal of Theoretical Biology, 1983
Abstract A strategy in a population game is evolutionarily stable if, when adopted by large enough a majority in the population, it becomes advantageous against any mutant strategy. It is said to be continuously stable if, when the majority slightly deviates from it, some reduction of this deviation becomes individually advantageous.
