cmaCalcFitness function

Calculate the fitness of a population.

The population is usually obtained by cmaSamplePopulation.

cmaCalcFitness(cma, popR, fitFunc)

Arguments

• cma: CMA-ES Java object, already initialized with cmaInit
• popR: a (dimension x popSize) matrix from cmaSamplePopulation
• fitFunc: a function to be minimized. Signature: accepts a vector x, returns a double.

Returns

fitness, a vector of length cmaGetPopulationSize(cma) with the fitness of each individuum

Examples

cma <- cmaNew();
   cmaInit(cma,dimension=2,initialX=1.5);
   popR <- cmaSamplePopulation(cma);
   fitFunc <- function(x) {sum(x*x)};
   fitness <- cmaCalcFitness(cma,popR,fitFunc);
   cmaUpdateDistribution(cma,fitness);
