pgasetrealinitrange
PGASetRealInitRange(2) PGAPack PGASetRealInitRange(2)NAME
PGASetRealInitRange - sets the upper and lower bounds for randomly initializing real-valued genes.
DESCRIPTION
For each gene these bounds define an interval from which the initial allele value is selected uniformly randomly. The user specifies two
arrays containing lower and bound for each gene to define the interval. This is the default strategy for initializing real-valued strings.
The default interval is $[0,1.0]$ for each gene.
INPUT PARAMETERS
ctx - context variable
min - array containing the lower bound of the interval for each gene
mac - array containing the upper bound of the interval for each gene
OUTPUT PARAMETERS
none
SYNOPSIS
#include "pgapack.h"
void PGASetRealInitRange(ctx, min, max)
PGAContext *ctx
double *min
double *max
LOCATION
real.c
EXAMPLE
Set the initialization routines to select a value for each real-valued
gene i uniformly randomly from the interval [-10.,i]
Assumes all strings are of the same length.
PGAContext *ctx;
double *low, *high;
int i, stringlen;
:
stringlen = PGAGetStringLength(ctx);
low = (double *) malloc(stringlen*sizeof(double));
high = (double *) malloc(stringlen*sizeof(double));
for(i=0;i<stringlen;i++) {
low[i] = -10.0;
high[i] = i;
}
PGASetRealInitRange(ctx, low, high);
