Re: But Fizbo have a big technical problem!

No problem - several days are a negligibly small timeframe in comparison with the typically long and hasteless careers of computer chess enthusiasts :wink:

The upcoming release of Fire 6 is a cool news, I hope its aggression hasn't been reduced from v.5.

As for Romi, I ran a 10-game mini-match with rook odds (3+3 time, 1 core for both) and she beat Fizbo +7 -3 =0, but I'm surprised that the score wasn't 10-0 and especially that there were no draws, and Fizbo's 3 swindles made early in the match (when Romi hadn't yet learned to navigate rook odds openings) were fabulous :lol: They're posted in the below PGN collection after 1 unsuccessful but also cute swindle attempt.

Re: Fizbo 1.9 released

Post by Tony P. » Tue Sep 19, 2017 11:48 pm

Here are a couple of quirks in the way Fizbo 1.9 writes PVs that are disturbing me.

1. In its comments to a game vs Andscacs 0.92, specifically, in the PVs for its moves 45 and 46, Fizbo wrote illegal moves (45. d7 c2 46. d8Q cxd1Q+ h5+ Qf4+), and as far as I remember, it was writing those moves in PVs during the game too (in the Arena GUI). I hope it's only a display bug and Fizbo did check those pseudolegal moves for legality during its search.

2. In the analysis of the final position of the following line,

Fizbo gives the 'normal' move 16. O-O in the 'final' PVs of each search iteration but the nonsensical 16. Qxe4 with an advantage for White in 'intermediate' PVs, not just the first few ones, but in every other variation throughout the search :shock:

Again, I hope it's just a display artifact, not a search bug.

Re: Fizbo 1.9 released

Post by Dann Corbit » Tue Sep 19, 2017 11:56 pm

Probably a hash error.
It happens especially when the pv is reconstructed from the hash.
The entry gets overwritten.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Re: Fizbo 1.9 released

If these are indeed hash errors (with the hash size set to 2 GB), then it's surprising that Fizbo is the 6th strongest engine in the world - I've seen such erratic PVs (always involving obviously incorrect weird sacrifices) many times in fewer than 100 Fizbo games played on my laptop, primarily in early search iterations. What's strange, though, is that these errors have never led to blunders on Fizbo's side - it always managed to find (in the last iteration) and play a 'normal' move despite considering a weird sac in the penultimate iteration.

On a side note, one probable hash error that did lead to a blunder that I remember (46... Qe7??) was made by iCE 3, not Fizbo, and iCE doesn't make this blunder in postmortem analysis.

Perhaps Fizbo's error occurs because the key length for one of the auxiliary hashes (most likely the material hash) is too small even when the TT is large.

The pv is probably not reconstructed until the very end of the search. When the pv was originally being formed, it is likely that the hash entries were correct.

This is actually a common programs for programs that recreate pvs from hash table afterwards.

That is why many of them also keep a triangular pv array to store it.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Judging by the fact that the Qxe4 'PVs' like 21/45- are printed almost instantly after the previous search iteration ends, I'm afraid you're right.

Another clue is that Fizbo's TT has 'dense 8 byte entries' - it looks like the TT has no buckets (that Stockfish has) and, indeed, there's no insurance against the overwriting of PV nodes.

Another instance of the same bug (here, 10... Bxg3? is suggested at 19/21+ and 20/37+):

(The 2 GB hash was 65% full after 4.5 minutes of analysis.)

This example shows a more typical behaviour of the search function - namely, that a nonsensical variation only appears in a few early iterations and then vanishes.

The impact of the bug on the overall playing strength might be small to medium, though (fixing it may make Fizbo the 4th strongest but still not an equal rival to SF, Komodo and Houdini yet). Even if it occurs once per game or a few games, it just affects the move ordering in the search on that single move and usually results in a small, if any, inaccuracy played because of a slower (thus shallower) search than normal.

I wonder if there's ever been a human master game where the eventual winner had 6 pawns fewer (not 6 pawns' worth of material but 6 pawns for piece(s)) at some point than the eventual loser (material imbalances FTW) :lol:
