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);
