cma_tell

Deliver function values to cma minimizer

Calling Sequence

es = cma_tell(es,X,arfitness)
es = %cma_tell(es,X,arfitness) // the same

Parameters

es

cma object

X

list of lambda column vectors of the search space

arfitness

vector of objective (cost) function values, such that arfitness(i) = cost_function(X(i))

es

updated cma object

Description

Examples

param.x0 = ones(8,1);
param.sigma0 = 0.5;
es = cma_new(param);
while ~ cma_stop(es) // es.out.stopflags is empty
  X = cma_ask(es);   // returns a list of lambda column vectors
  y = [];
  for i = 1:length(X)
    y(i) = costf(X(i)); // costf needs to be defined
  end
  es = cma_tell(es, X, y');
end
