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.
