NAME
PGASortPop - Creates an (internal) array of indices according to one of three criteria. DESCRIPTION
If PGA_POPREPL_BEST is used (the default) the array is sorted from most fit to least fit. If PGA_POPREPL_RANDOM_REP is used the indices in the array are selected randomly with replacement. If PGA_POPREPL_RANDOM_NOREP is used the indices in the array are selected randomly with- out replacement. The function PGASetPopReplaceType() is used to specify which strategy is used. The indices of the sorted population mem- bers may then be accessed from the internal array via PGAGetSortedPopIndex(). This routine is typically used during population replace- ment. INPUT PARAMETERS
ctx - context variable popindex - symbolic constant of the population from which to create the srted array. OUTPUT PARAMETERS
none SYNOPSIS
#include "pgapack.h" void PGASortPop(ctx, pop) PGAContext *ctx int pop LOCATION
pop.c EXAMPLE
Example: Copy the five best strings from the old population into the new population. The rest of the new population will be created by recombination, and is not shown. PGAContext *ctx; int i,j; : PGASetPopReplaceType(ctx,PGA_POPREPL_BEST) : PGASortPop(ctx, PGA_OLDPOP); for ( i=0; i < 5; i++) { j = PGAGetSortedPopIndex(ctx, i); PGACopyIndividual (ctx, j, PGA_OLDPOP, i, PGA_NEWPOP); : 05/01/95 PGASortPop(8)
