Member Function Documentation

void MultiobjectiveProblem::adjustPrecision (  int  variable,
VariableType  variableType
) 
 

Parameters:
variable The identifier of the variable
variableType The type of representation

double MultiobjectiveProblem::calculateMutationProbability (   ) 
 

Returns:
The mutation probability
If the genes are binary, the mutation probability is 1 divided by the total number of bits of the chromosome. If the genes are real, the mutation probability is 1 divided by the number of genes. It is assumed that all the genes are either binary or either real
