Detailed Description

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

Mutation component of an ES.

Mutates the objective values with a normal distributed variate. In difference to AdaptiveNormalMutation this mutation does not add a mutation offset to the mutated value but it scales the value. The strategic parameter will be mutated by a log-normal distributed variate before used for the mutation of the objective parameters. The default value of the strategic parameters is 1.0.
s'[i] = s[i] * LN(0,a)
v[i] = N(0,s'[i])
v[i] < 0 : x'[i] = x[i] * 1/(1-(v[i]*gs[i]))
v[i] >= 0 : x'[i] = x[i] * (1+(v[i]*gs[i]))

s[i]: strategic parameter (related to the i-th objective parameter)(before mutation);
s'[i]: strategic parameter (related to the i-th objective parameter)(after mutation);
a: variance of strategic mutation;
v[i]: variate for the the i-th objective parameter;
x[i]: the i-th objective parameter (before mutation);
x'[i]: the i-th objective parameter (after mutation);
gs[i]: general scale of the i-th objective parameter;
