Function PGACreate

Defined in File create.c

Function Documentation

PGAContext *PGACreate(int *argc, char **argv, int datatype, int len, int maxormin)

Create an uninitialized context variable.

Description

The Fortran version of this function call contains only the last three arguments.

The datatype must be one of PGA_DATATYPE_BINARY, PGA_DATATYPE_CHARACTER, PGA_DATATYPE_INTEGER, PGA_DATATYPE_REAL, or PGA_DATATYPE_USER to specify binary-valued, character-valued, integer-valued, real-valued, or a user-defined datatype, respectively. See Constants for Datatypes for the constants and types.

The maxormin parameter must be one of PGA_MAXIMIZE or PGA_MINIMIZE for maximization or minimization, respectively. See Constants for Optimization Direction for the constants.

Example

In C:

void main (int argc, char **argv) {
    PGAContext *ctx;

    ctx = PGACreate (&argc, argv, PGA_DATATYPE_BINARY, 100, PGA_MAXIMIZE);
    //  Set options here
    PGASetUp (ctx);
    //  Run the GA here
    PGADestroy (ctx);
}

In Fortran:

        integer ctx

        ctx = PGACreate(PGA_DATATYPE_BINARY, 100, PGA_MAXIMIZE)
c       Set options here
        call PGASetUp(ctx)
c       Run the GA here
        call PGADestroy(ctx)
        stop
        end

Parameters:

argc – Address of the count of the number of command line arguments
argv – Array of command line arguments
datatype – The data type used for the strings
len – The string length (number of genes)
maxormin – The direction of optimization.

Returns:

A pointer to the context variable
