An Optimal Strategy of Evolution
The Quarterly Review of Biology, 1974Admissable game-theory models of evolution must be restricted to the class of "existential games" in which there is no way of using the winnings ("payoff") for any purpose other than continuing the game for as long as possible. The optimal strategy in such a game is to minimize the stakes played.

HEDGING STRATEGY WITH LANGEVIN EVOLUTION
International Journal of Theoretical and Applied Finance, 2000In recent years there has been much attention paid to pricing and hedging models that are more general than the Black and Scholes' one, whose hypotheses often aren't satisfied by true market data. Sato and Takayasu proposed a market model that can produce price fluctuations with infinite variance from a deterministic behaviour of many market's dealers

Contemporary evolution strategies
1995After an outline of the history of evolutionary algorithms, a new (μ, κ, λ, ρ) variant of the evolution strategies is introduced formally. Though not comprising all degrees of freedom, it is richer in the number of features than the meanwhile old (μ, λ) and (μ+λ) versions. Finally, all important theoretically proven facts about evolution strategies are

There is an embarrassing lack of surprises in certain aspects of evolutionary theory. For example, if a bird has only seawater to drink, it is not surprising, given our knowledge of birds in general, that some mechanism must exist for eliminating salt if the bird is to survive.

Inertia in strategy switching transforms the strategy evolution
Physical Review E, 2011A recent experimental study [Traulsen et al., Proc. Natl. Acad. Sci. 107, 2962 (2010)] shows that human strategy updating involves both direct payoff comparison and the cost of switching strategy, which is equivalent to inertia. However, it remains largely unclear how such a predisposed inertia affects 2 × 2 games in a well-mixed population of finite ...

Molecular strategies in Metazoan genomic evolution
Gene, 2002During the evolution of Metazoa, the mitochondrial genome has remained practically unchanged as indicated by its small size and constant gene content in each lineage, although several evolutionary processes have taken place. In contrast, the nuclear genome of Metazoa has undergone dramatic changes, as is demonstrated by some entire genomes completely ...

Bidirectional Relation between CMA Evolution Strategies and Natural Evolution Strategies
2010This paper investigates the relation between the covariance matrix adaptation evolution strategy and the natural evolution strategy, the latter of which is recently proposed and is formulated as a natural gradient based method on the expected fitness under the mutation distribution.

Selection strategies and artificial evolution
Theoretical and Applied Genetics, 1989Artificial selection results in biolgical changes, creating artificial evolution. When using selection indexes, the artificial evolution depends on the relative economic (or other) weight of traits in the breeding objective, and on the phenotypic and genetic variances and covariances among these traits and the traits recorded in the selection index. As

1996
The applications of conventional game theory to economics and decision theory have not been as successful as some of the field’s initiators had hoped for. It was indeed noted by von Neuman and Morgenstern [1] that some of game theory’s most serious limitations were due to its lacking dynamics.
