.TH PGASetRealInitPercent 2 "05/01/95" " " "PGAPack"
.SH NAME
PGASetRealInitPercent \- sets the upper and lower bounds for randomly
initializing real-valued genes.
.SH DESCRIPTION
For each gene these bounds define an
interval from which the initial allele value is selected uniformly randomly.
With this routine the user specifies a median value and a percent offset
for each allele.
.SH INPUT PARAMETERS
.PD 0
.TP
ctx
- context variable
.PD 0
.TP
median
- an array containing the mean value of the interval
.PD 0
.TP
percent
- an array containing the percent offset to add and subtract to
the median to define the interval
.PD 1
.SH OUTPUT PARAMETERS
.PD 0
.TP
none
.PD 1
.SH SYNOPSIS
.nf
#include "pgapack.h"
void PGASetRealInitPercent(ctx, median, percent)
PGAContext *ctx
double *median
double *percent
.fi
.SH LOCATION
real.c
.SH EXAMPLE
.nf
Set the initialization routines to select a value for each real-valued
gene i uniformly randomly from the interval [i-v,i+v], where $v = i/2$.
Assumes all strings are the same length.
PGAContext *ctx;
double *median, *percent;
int i, stringlen;
:
stringlen = PGAGetStringLength(ctx);
median = (double *) malloc(stringlen*sizeof(double));
percent = (double *) malloc(stringlen*sizeof(double));
for(i=0;i<stringlen;i++) {
median[i] = (double) i;
percent[i] = 0.5;
}
PGASetRealInitPercent(ctx, median, percent);
.fi
