Function Documentation

unsigned int PGAGetIntegerFromGrayCode(PGAContext *ctx, int p, int pop, int start, int end)

Interpret a binary reflected Gray code sequence as encoding an integer value and return the integer value it represents.

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);

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

Returns

The integer value encoded by the binary reflected Gray code sequence
