PGAGetIntegerFromGrayCode(3)

NAME

PGAGetIntegerFromGrayCode - interpets a binary reflected Gray code sequence as encoding an integer value and returns the integer value it represents.

INPUT PARAMETERS

ctx

- context variable

p

- string index

pop

- symbolic constant of the population the string is in

start

- starting bit position in the binary representation

end

- ending bit position in the binary representation

OUTPUT PARAMETERS

none

SYNOPSIS

#include "pgapack.h"
int  PGAGetIntegerFromGrayCode(ctx, p, pop, start, end)
PGAContext *ctx
int p
int pop
int start
int end

EXAMPLE

Example:
Get an integer j from bits 10--29 of string p in population PGA_NEWPOP.
The string is encoded in Gray code.
PGAContext *ctx;
int j, p;
:
j = PGAGetIntegerFromGrayCode(ctx, p, PGA_NEWPOP, 10, 29);
