Defined in File evaluate.c

Function Documentation

void PGAEncodeRealAsGrayCode(PGAContext *ctx, int p, int pop, int start, int end, double low, double high, double val)

Encode a real value as a binary reflected Gray code sequence.

Example

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 code sequence.

PGAContext *ctx;
int p;

...
PGAEncodeRealAsGrayCode (ctx, p, PGA_NEWPOP, 0, 29, 0.0, 10.0, 3.14);

Parameters

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 – upper bound of the interval the val is defined on
val – the real number to be represented as a binary string

Returns

The string is modified by side-effect
