On-line engine blitz tourney June

[Henk]

Aspiration search III applied when plyCount = 0. Second version rewritten by Sven.

Code: Select all

   
               int WINDOW_MARGIN = 2000;

                int factor = 1;
                int lb = guess.Value - factor * WINDOW_MARGIN;
                int ub = guess.Value + factor * WINDOW_MARGIN;

                           
                while (true)
                {
                    int value = Search(initValue, depth, 0, lb, ub);
                    if (!Position.Expired && (value <= lb || value >= ub))
                    {
                        factor = factor * 4;
                        if (value <= lb)
                        {
                            lb = guess.Value - factor * WINDOW_MARGIN;
                        }
                        else
                        {
                            ub = guess.Value + factor * WINDOW_MARGIN;
                        }
                     }
                    else break;
                 }

Aspiration windows ? Magic bitboards ?
Sooo you reinvent the wheel too ?
I'm very pleased to read that

[Henk]

I think I'm too stupid to invent anything new that gives a gain. Or maybe by luck. But old ideas like aspiration windows does not give much either.

[Daniel Anulliero]

O yes before I forget: Skipper used Aspiration Windows which were giving a huge ELO boost.

You guy are very funny ! Huge elo boost ?
It lose in 18 moves against my weak engine Isa ( who is rated 2110 elo , according to CCRL elos)
Please stop writing nonsenses and stop trolling
Thanks
