PGASetRealInitPercent(2)					      PGAPack						  PGASetRealInitPercent(2)

NAME
       PGASetRealInitPercent - 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.  With this routine the
       user specifies a median value and a percent offset for each allele.

INPUT PARAMETERS
       ctx    - context variable
       median - an array containing the mean value of the interval
       percent
	      - an array containing the percent offset to add and subtract to the median to define the interval

OUTPUT PARAMETERS
       none

SYNOPSIS
       #include "pgapack.h"
       void  PGASetRealInitPercent(ctx, median, percent)
       PGAContext *ctx
       double *median
       double *percent

LOCATION
       real.c

EXAMPLE
       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);
