Hi,
You've defined argv as an array of characters, rather than an array of character arrays (i.e. strings). Change your 'main' function definition to this (note the asterisk):
int main(int argc,char *argv[]){
Or, my prefered way of writing it:
int main(int argc,char **argv){
Kind regards,
Andy Barry

PGACreate - creates an uninitialized context variable. The Fortran version of this function call contains only the last three arguments
INPUT 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. Must be one of PGA_DATATYPE_BINARY, PGA_DATATYPE_CHARACTER, PGA_DATATYPE_INTEGER,
PGA_DATATYPE_REAL, or PGA_DATATYPE_USER
binary -valued, character-valued, integer-valued,
real -valued, or a user-defined datatype, respectively.
len - the string length (number of genes).
maxormin
- the direction of optimization. Must be one of PGA_MAXIMIZE or PGA_MINIMIZE for maximization or minimization, respectively.
OUTPUT PARAMETERS
none
SYNOPSIS
#include "pgapack.h"
PGAContext * PGACreate(argc, argv, datatype, len, maxormin)
int *argc
char **argv
int datatype
int len
int maxormin
LOCATION
create.c
EXAMPLE
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
