NAME
PGAChange - Repeatedly apply mutation to a string (with an increasing
mutation rate) until one or more mutations have occurred.
DESCRIPTION
This routine is usually used with PGADuplicate to modify a duplicate
string. It is not intended to replace PGAMutation
INPUT PARAMETERS
ctx - context variable
p - string index
pop - symbolic constant of the population containing string p
OUTPUT PARAMETERS
none
SYNOPSIS
#include "pgapack.h"
void PGAChange(ctx, p, pop)
PGAContext *ctx
int p
int pop
LOCATION
duplcate.c
EXAMPLE
Example:
Change any string in PGA_NEWPOP that is an exact copy of a string
in PGA_OLDPOP. To be complete, we should check the population again
if any changes are made; for simplicity, we don’t.
PGAContext *ctx;
int b, n;
:
n = PGAGetPopsize(ctx);
for (b=0; b<n; b++)
if (PGADuplicate(ctx, b, PGA_NEWPOP, PGA_OLDPOP, n))
PGAChange(ctx, b, PGA_NEWPOP);
