NAME

PGASetFitnessMinType - sets the type of algorithm used if a minimization problem is specified to determine how values are remapped for maximization.

DESCRIPTION

Valid choices are PGA_FITNESSMIN_RECIPROCAL and PGA_FITNESSMIN_CMAX to do the mapping using the reciprocal of the evaluation function, or by subtracting the worst evaluation function value from each evaluation function value, respectively. The default is PGA_FITNESSMIN_CMAX

INPUT PARAMETERS

ctx
- context variable
fitness_type
- symbolic constant to specify fitness minimization type

OUTPUT PARAMETERS
