PGADuplicate(8) 						      PGAPack							   PGADuplicate(8)

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 containing strings to compare string p against n - the number of strings in pop2 to compare string p against n -1) OUTPUT PARAMETERS
#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); 05/01/95 PGADuplicate(8)
