When "go infinite" is called it only shows 1 move and not a longer line of moves ?!

[JohnWoe]

When "go infinite" is called it only shows 1 move and not a longer line of moves ?!

If calling from console. Mayhem assumes it has no time and just returns the first book / generated move.

Code: Select all

go infinite
info depth 1 nodes 0 time 0 nps 0 score cp 0 pv c2c4
bestmove c2c4

If you mean why the primary variation is only 1 move. Yes that's by design. Of course I store moves in hashtable. 3 per line actually. So Mayhem remembers the best lines. But not always, like with full pv. I just don't do this copy-pv-line thing like in other engines. Because it was much slower than what I have. Not that great for analysing.

There was some "potential" problems in 7.3. Such as log(0) which is impossible. But clang didn't seem to have problems w/ it.
Noticed it after working on Havoc...

I updated to a better book and got +88 Elo. Probably much less irl.
Style is now not-so-risky as Mayhem uses 3 rep draw not 2 rep.
