PGASetUserFunction(8) PGAPack PGASetUserFunction(8)NAME
PGASetUserFunction - specifies the name of a user-written function call to provide a specific GA capability (e.g., crossover, mutation,
etc.).
DESCRIPTION
This function MUST be used when using a non-native datatype and must be called once for each of:
PGA_USERFUNCTION_CREATESTRING -- String creation
PGA_USERFUNCTION_MUTATION -- Mutation
PGA_USERFUNCTION_CROSSOVER -- Crossover
PGA_USERFUNCTION_PRINTSTRING -- String Output
PGA_USERFUNCTION_COPYSTRING -- Duplication
PGA_USERFUNCTION_DUPLICATE -- Duplicate Checking
PGA_USERFUNCTION_INITSTRING -- Initialization
PGA_USERFUNCTION_BUILDDATATYPE -- MPI Datatype creation
PGA_USERFUNCTION_STOPCOND -- Stopping conditions
PGA_USERFUNCTION_ENDOFGEN -- Auxiliary functions at the end of each generation
It MAY be called when using a native datatype to replace the built-in functions PGAPack has for that datatype (For example, if the Integer
data type is used for a traveling salesperson problem, the user may want to provide their own custom crossover operator). See the user
guide and the examples in the examples directory for more details.
INPUT PARAMETERS
ctx - context variable
constant
- symbolic constant of the user function to set
f - name of the function to use
OUTPUT PARAMETERS
none
SYNOPSIS
#include "pgapack.h"
void PGASetUserFunction(ctx, constant, f)
PGAContext *ctx
int constant
void *f
LOCATION
user.c
EXAMPLE
Example:
void MyStringInit(PGAContext *, void *);
PGAContext *ctx;
:
PGASetUserFunction(ctx, PGA_USERFUNCTION_INITSTRING, MyStringInit);
