This is the command PGAEvaluate that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
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)
MPI_Comm comm
LOCATION

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);
