PGADuplicate(8)
NAME
PGADuplicate - determines if a specified string is a duplicate of one
already in an existing population
INPUT PARAMETERS
- ctx - context variable
p - string index
pop1 - symbolic constant of the population containing string p
pop2 - symbolic constant of the (possibly partial) population con - taining strings to compare string p against
- n - the number of strings in pop2 to compare string p against
n -1)
OUTPUT PARAMETERS
none
SYNOPSIS
#include "pgapack.h" int PGADuplicate(ctx, p, pop1, pop2, n) PGAContext *ctx int p int pop1 int pop2 int n
LOCATION
duplcate.c
EXAMPLE
0,...,n-1 in population pop2. Otherwise returns PGA_FALSE
Example:
Change any string in PGA_NEWPOP that is an exact copy of a string
in PGA_OLDPOP.
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);
Check if the best string in population PGA_OLDPOP is a duplicate of any
of the strings in the first half of population PGA_NEWPOP.
- PGAContext *ctx;
int b, n;
:
b = PGAGetBestIndex(ctx, PGA_OLDPOP);
n = PGAGetPopsize(ctx) / 2;
if (PGADuplicate(ctx, b, PGA_OLDPOP, PGA_NEWPOP, n))
printf("A duplicate!0);
