PGARank(4)

NAME
PGARank - returns the rank of a string in a population. This is a value between 1,...,N (the population size). The most fit string has rank 1. The least fit string has rank N.

INPUT PARAMETERS
ctx - context variable
p   - the index of the string whose rank is desired
order
    - an array containing a unique rank for each string
n   - the size of the array order

OUTPUT PARAMETERS
none

SYNOPSIS
#include "pgapack.h"
int  PGARank(ctx, p, order, n)
PGAContext *ctx
int p
int *order
int n

LOCATION
fitness.c

EXAMPLE
Example:
To determine the rank of string p use
PGAContext *ctx;
int i, popsize, rank, *order;
double *fitness;
popsize = PGAGetPopsize(ctx);
order   = (int *)   malloc(sizeof(int)    * popsize);
fitness = (double *)malloc(sizeof(double) * popsize);
for(i=0;i<popsize; i++) {
fitness[i] = PGAGetFitness(ctx,p,PGA_OLDPOP);
order[i]   = i;
}
PGADblHeapSort ( ctx, fitness, order, popsize);
rank = PGARank(ctx,p,order,n)
