I said that random generators suck.
That's misleading:) You claim that although PRNG may be very good at
producing random numbers, the latter are no good for Zobrist hashing.
I'm not convinced:(
That did not imply that that the solution is a "perfect" random generator.
Even a "perfect" random generator will give piss-poor performance for a
64-bit Z-hasher. So, herewith I have basically disclosed part of the
"secret": DO NOT, UNDER ANY CIRCUMSTANCES, USE RANDOM VALUES AS HASH
KEYS. Never ever. Not even when you use white noise from a resistor or
diode. It simply gives sub-par performance.
I've never seen any evidence or discussion of this. I certainly cannot
imagine that specially chosen 60-bit numbers are better than randomly
chosen 64-bit values. So I see no basis for your claim above.
