evolution strategy
(ES) A kind of evolutionary algorithm where individuals (potential solutions)
are encoded by a set of real-valued "object variables" (the individual's
"genome"). For each object variable an individual also has a "strategy variable"
which determines the degree of mutation to be applied to the corresponding
object variable. The strategy variables also mutate, allowing the rate of
mutation of the object variables to vary.
An ES is characterised by the population size, the number of offspring produced
in each generation and whether the new population is selected from parents and
offspring or only from the offspring.
ES were invented in 1963 by Ingo Rechenberg, Hans-Paul Schwefel at the Technical
University of Berlin (TUB) while searching for the optimal shapes of bodies in a
flow.
