Evolutionary algorithms | Optimization algorithms and methods | Stochastic optimization
Natural evolution strategies (NES) are a family of numerical optimization algorithms for black box problems. Similar in spirit to evolution strategies, they iteratively update the (continuous) parameters of a search distribution by following the natural gradient towards higher expected fitness. (Wikipedia).

3. Adaptive Evolution: Natural Selection
Principles of Evolution, Ecology and Behavior (EEB 122) Adaptive Evolution is driven by natural selection. Natural selection is not "survival of the fittest," but rather "reproduction of the fittest." Evolution can occur at many different speeds based on the strength of the selection dr

Evolution - key moments in evolution
Nematodes show scientists how evolution works. Tried and tested processes are used in different ways than usual and recombined with others. This way, an organism can quickly evolve new features.

Mechanisms of Natural Selection: Altruism and Kin Selection
We have learned all about so-called "survival of the fittest" which is a phrase we associate with natural selection. We typically associate this concept with competition for resources, but there are situations in which this involves the complete opposite, in the form of cooperative and alt

11. Evolutionary stability: cooperation, mutation, and equilibrium
Game Theory (ECON 159) We discuss evolution and game theory, and introduce the concept of evolutionary stability. We ask what kinds of strategies are evolutionarily stable, and how this idea from biology relates to concepts from economics like domination and Nash equilibrium. The informal
