PGAEncodeRealAsGrayCode(1) PGAPack PGAEncodeRealAsGrayCode(1)NAME
PGAEncodeRealAsGrayCode - encodes a real value as a binary reflected Gray code sequence
ctx - context variable
p - string index
pop - symbolic constant of the population the string is in
start - starting bit position in p to encode val in
end - ending bit position in p to encode val in
low - lower bound of the interval the val is defined on
high - lower bound of the interval the val is defined on
val - the real number to be represented as a binary string
void PGAEncodeRealAsGrayCode(ctx, p, pop, start, end, low, high, val)
Encode 3.14 from the interval [0,10] in 30 bits in bit positions
0--29 in string p in population PGA_NEWPOP as a binary reflected Gray
PGAEncodeRealAsGrayCode(ctx, p, PGA_NEWPOP, 0, 29, 0.0, 10.0, 3.14);

PGASetIntegerInitRange - sets a flag to tell the initialization routines to set each integer-valued gene to a value chosen randomly from
the interval given by an upper and lower bound.
No string initialization is done by this call.
ctx - context variable
min - array of lower bounds that define the interval the gene is initialized from
max - array of upper bounds that define the interval the gene is initialized from
void PGASetIntegerInitRange(ctx, min, max)
Set the initialization routines to select a value for gene i
uniformly randomly from the interval [0,i]. Assumes all strings
are of the same length.
int *low, *high, stringlen, i;
stringlen = PGAGetStringLength(ctx);
low = (int *) malloc(stringlen*sizeof(int));
high = (int *) malloc(stringlen*sizeof(int));
low[i] = 0;
high[i] = i
PGASetIntegerInitRange(ctx, low, high);
