PGADuplicate(8) 						      PGAPack							   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 containing 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);

NAME

       PGASendReceiveIndividual - Send an individual to a process, while receiving a different individual from a different process.

INPUT PARAMETERS

       ctx    - context variable
       send_p - index of string to send
       send_pop
	      - symbolic constant of population to send from
       dest   - destination process
       send_tag
	      - tag to send with
       recv_p - index of string to receive
       recv_pop
	      - symbolic constant of population to receive from
       source - process to receive from
       recv_tag
	      - tag to receive with
       comm   - an MPI communicator
       status - pointer to the MPI status structure

OUTPUT PARAMETERS

       none

SYNOPSIS

       #include "pgapack.h"
       void  PGASendReceiveIndividual(ctx, send_p, send_pop, dest, send_tag, recv_p, recv_pop, source, recv_tag, comm, status)
       PGAContext *ctx
       int send_p
       int send_pop
       int dest
       int send_tag
       int recv_p
       int recv_pop
       int source
       int recv_tag
       MPI_Comm comm
       MPI_Status *status

LOCATION

       parallel.c

EXAMPLE

       Example:
       A dedicated process is being used to perform an optimization algorithm
       on the strings.	Send a new string, s, to the process, while receiving an
       optimized string, r, from it.

       PGAContext *ctx;
       MPI_Comm    comm;
       MPI_Status  status;
       int  s, r;
       :
       PGASendReceiveIndividual(ctx, s, PGA_NEWPOP, 1, PGA_SR_STRINGTOMODIFY,
       r, PGA_NEWPOP, 1, PGA_SR_MODIFIEDSTRING,
       comm, &status);
