PGARank(1)
NAME
PGARank - returns the rank of a string in a population.
DESCRIPTION
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

EXAMPLE
Example:
Determine the rank of string p.
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, popsize)
