You were laughing towards me. Even you posted a 'smile'.
As for a few minutes you thought you could beat the combination of
rotation with addition with just addition.
|
I am still smiling. Really there is no point to do additional rotations when you have two good thoroughly randomized hash keys in [piece] and [square]. It beats anything else because it requires one simple operation given those tables.
You suggested a rotation method while using tables..what is the point in that? It sure is going to be dog slow compared to simple addition.

Don acked you in that.
Also explicitly mentions only addition.
That's 2 of you.
Fact is what i posted is about a 5x faster than what you showed up with.
|
You don't get what is being said. Like I said addition is the simplest there is given two tables. You _also_ use tables so the rotations are unnecessary.
Even the method I suggested later that produces the keys from scratch is different from yours. RanRot does two fixed rotations of 5 and 3, so it automatically means use of tables. But if you just rotate by 1 bit for each square (upto 64), you can avoid table lookups...

p.s. it's good habit to remove the 'you are so dumb' you initially posted.

I was out of line and apologize for that.
