PGAChange8

Repeatedly apply mutation to a string (with an increasing mutation rate) until one or more mutations have occurred.

Usage

void PGAChange(ctx, p, pop)

PGAContext *ctx

int p

int pop

Overview

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

Location

duplcate.c

Examples

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);
