Re: hash collisions

The problem here, is that now we are using a completely new definition of bug, "any software defect detected by the end user is a bug, nothing else counts." So, question 1, "given that it is impossible to produce a linear speedup with alpha/beta, if a program is 50% efficient in parallel search, me...

Re: hash collisions

You don't like it when your stupidity receives extra attention? Hahahaha! 100% no bugs for chess engines is entirely possible, the mechanics of moving the six pieces in defined ways over 64 squares and performing recursive search are quite trivial. Programmers who won’t work to 100% bug free method...

He even considers it a bug, and reason to be fired over, if someone comes up with a more efficient algorithm than he himself would have used. :lol:
You two mutually massaging each other is funny.

Re: hash collisions

Then show a list of bugs “that have been there for a while”. Do you not realize how silly that sounds? Still on the NPD put-downs? Can't help yourself? And no, it doesn't sound silly at all. Someone said there's a list of bugs, so I responded, ok show us the list of bugs. Why would you think that w...

Re: hash collisions

It has not been suggested here yet, but a consideration to look at for hash collision testing is the Hamming Distance https://www.chessprogramming.org/Population_Count#HammingDistance . Some programs like Crafty and Fruit use preset hash keys, but other engines are generating random numbers for eve...

Re: hash collisions

Last one with a full year of usage was Stockfish 10, you have a list of actual real bugs and how they were dealt with? Here's a list of all changes from Stockfish 10 to Stockfish 11: a change list is not a bug list https://github.com/snicolet/Stockfish/commit/d531291e46c281da20110cb8f5a8984fb970358...
