NAME
PGAEvaluate - Calls a user-specified function to return an evaluation of each string in the population.
DESCRIPTION
The user-specified function is only called if the string has been changed (e.g., by crossover or
mutation) or the user has explicitly signaled the string's evaluation is out-of-date by a call to
PGASetEvaluationUpToDateFlag().
INPUT PARAMETERS
ctx - context variable
pop - symbolic constant of the population to be evaluated
f - a pointer to a function to evaluate a string. This function will be called once for each string
in population pop that requires evaluation. This function must return a double (the evaluation
function value) and must fit the prototype double f(PGAContext *c, int p, int pop);
comm - an MPI communicator
OUTPUT PARAMETERS
none
SYNOPSIS
#include "pgapack.h"
void PGAEvaluate(ctx, pop, , comm)
PGAContext *ctx
int pop
double (*f)(PGAContext *, int, int)

EXAMPLE
Example:
Evaluate all strings in population PGA_NEWPOP using the user-defined
evaluation function Energy.
double Energy(PGAContext *ctx, int p, int pop) {
:
};
PGAContext *ctx;
:
PGAEvaluate(ctx, PGA_NEWPOP, Energy, MPI_COMM_WORLD);
