Detailed Description

template<class TIndividual>
class FREE::ES::AdaptiveCovarianceMutation< TIndividual >

Mutation component of a ES.

Mutates the objective values with the use of a covariance matrix and a delta vector consisting of n normal distributed variates (n: number of objective parameters). The covariance matrix is defined by n variances (v) and ((n-1)*n)/2 orientation angels (a). The elements of the covariance matrix c(i,j) are defined by following term:
tan(2*a(i,j)) = c(i,j)/v(i)² - v(j)²
of the variate for each objectiv parameter is stored as strategic parameter. The strategic parameter will be mutated by a log-normal distributed variate before used for the mutation of the objective parameters. The devault value of the stragic parameters is 1.0.
s'[i] = s[i] * LN(0,a)
x'[i] = x[i] + (N(0,s'[i]) / gs[i]) s[i]: strategic parameter (related to the i-th objective parameter)(befor mutation); s'[i]: strategic parameter (related to the i-th objective parameter)(after mutation); a: variance of strategic mutation; x[i]: the i-th objectiv parameter (befor mutation); x'[i]: the i-th objectiv parameter (after mutation); gs[i]: general scale of the i-th objective parameter;
