Function Documentation

void PGAEncodeIntegerAsGrayCode(PGAContext *ctx, int p, int pop, int start, int end, unsigned int val)

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

Example

Encode an integer 7 in 20 bits in bit positions 0–19 in string p in population PGA_NEWPOP using Gray code.

PGAContext *ctx;
int p;

...
PGAEncodeIntegerAsGrayCode (ctx, p, PGA_NEWPOP, 0, 19, 7);

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

• val – the integer value to be represented as a binary reflected Gray code sequence

Returns:

The string is modified by side-effect
