PGASetIntegerInitPermute(2)					      PGAPack					       PGASetIntegerInitPermute(2)

NAME

       PGASetIntegerInitPermute  -  sets a flag to tell the initialization routines to set each integer-valued gene to a random permutation of the
       values given by an upper and lower bound.

DESCRIPTION

       The length of the interval must be the same as the string length.  This is the default strategy for  initializing  integer-valued  strings.
       The default interval is [0,L-1] where L is the string length.  No string initialization is done by this call.

INPUT PARAMETERS

       ctx    - context variable
       min    - the lower bound of numbers used in the permutation
       max    - the upper bound of numbers used in the permutation

OUTPUT PARAMETERS

       none

SYNOPSIS

       #include "pgapack.h"
       void  PGASetIntegerInitPermute(ctx, min, max)
       PGAContext *ctx
       int min
       int max

LOCATION

       integer.c

EXAMPLE

       Set the initialization routines to set each gene to a random and
       unique value from the interval $[500,599]$.

       PGAContext *ctx;
       :
       PGASetIntegerInitPermute(ctx, 500, 599)}

PGAEvaluate(1)							      PGAPack							    PGAEvaluate(1)

NAME

       PGAEvaluate - Calls a user-specified function to return an evaluation of each string in the population.

DESCRIPTION

       The  user-specified function is only called if the string has been changed (e.g., by crossover or mutation) or the user has explicitly sig-
       naled the string's evaluation is out-of-date by a call to PGASetEvaluationUpToDateFlag().

INPUT PARAMETERS

       ctx    - context variable
       pop    - symbolic constant of the population to be evaluated
       f      - a pointer to a function to evaluate a string.  This function will be called once for each string in population pop  that  requires
	      evaluation.   This  function must return a double (the evaluation function value) and must fit the prototype double f(PGAContext *c,
	      int p, int pop);
       comm   - an MPI communicator

OUTPUT PARAMETERS

       none

SYNOPSIS

       #include "pgapack.h"
       void  PGAEvaluate(ctx, pop, , comm)
       PGAContext *ctx
       int pop
       double (*f)(PGAContext *, int, int)
       MPI_Comm comm

LOCATION

       parallel.c

EXAMPLE

       Example:
       Evaluate all strings in population PGA_NEWPOP using the user-defined
       evaluation function Energy.

       double Energy(PGAContext *ctx, int p, int pop) {
       :
       };

       PGAContext *ctx;
       :
       PGAEvaluate(ctx, PGA_NEWPOP, Energy, MPI_COMM_WORLD);
