PGADebugPrint(3)						      PGAPack							  PGADebugPrint(3)

NAME

       PGADebugPrint - Write debugging information

INPUT PARAMETERS

       ctx    - context variable
       level  -  a symbolic constant that maps to the type of print requested (e.g., an entry or exit print).  Valid values are PGA_DEBUG_ENTERED,
	      PGA_DEBUG_EXIT, PGA_DEBUG_MALLOC, PGA_DEBUG_PRINTVAR, PGA_DEBUG_SEND, and PGA_DEBUG_RECV.
       funcname
	      - the name of the function that called this routine
       msg    - message to print
       datatype
	      - a symbolic constant that maps to the data type of the parameter  data.	 Valid	choices  are  PGA_INT,	PGA_DOUBLE,  PGA_CHAR  and
	      PGA_VOID (no data).
       data   - a pointer, whose contents will be interpreted based upon the datatype parameter (or NULL, if PGA_VOID).

OUTPUT PARAMETERS

       none

SYNOPSIS

       #include "pgapack.h"
       void  PGADebugPrint(ctx, level, funcname, msg, datatype, data)
       PGAContext *ctx
       int level
       char *funcname
       char *msg
       int datatype
       void *data

LOCATION

       debug.c

EXAMPLE

       Example:
       If the debugging level includes printing variables (level 82), print the
       value of the integer variable num as a debugging tool in the routine
       Add2Nums

       PGAContext *ctx;
       int num;
       :
       PGADebugPrint(ctx, PGA_DEBUG_PRINTVAR, "Add2Nums", "num = ", PGA_INT,
       (void *) &num);

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);
       :
