How long to see Rdf1 ?
Crafty 22.8 seems to struggle a little on this and first gets Rdf1 on ply 18 here
Just another test position

Re: Crafty 22.8
I do not understand all of Crafty's output, I interpret the numbers between brackets as seconds but in the last lines there is a number of 1.04 seconds, if that is for 18 plies that would be very fast even for Crafty 
Blueberry finds Rdf1 at plydepth 9 but in case of Blueberry it is more useful to look at the time, 33 seconds or at the number of nodes which are counted just as in other Togas. All of the recent changes are geared a bit to finding better moves hidden somewhere in the move-list so there is the risk of not doing enough research on the Principal Variation, on the first move. There has to be some kind of balance between the two.

Re: Crafty 22.8
If I divide the new Swindle-code by two I get a bit faster result but actually the old Build 269 is faster. Build 271 is interesting because the follow-up is with 2... Qg4 and waiting to see if White initiates a Queen swap.

It is not yet clear in which direction the 'trade factor' work best here but clearly this kind of factoring can have a big impact on the results. Normally you rely on pawns or maybe some of the pieces in the endgame getting a bigger value to decide if trading pieces or pawns is favourable or unfavourable in addition to any positional extras. But probably that is not enough to value trading of pieces and pawns with any accuracy if one player is already down.
I am not sure 2... Qg4 is better because I checked with Rybka 2.2n2 and although Rybka first agrees with 2... Qg4 later she goes back to 2... Qf6.

are, by definition, not smart enough to debug it.

Re: Just another test position
Here's Neurosis's output, which I'm posting for no other reason then that after a break (last public version dated mid-2007) I'm working on it again, and felt like doing a deep search. Rdf1 is found just under 3 minutes.
P-D 3.4GHz (1cpu), 128MB hash. (my engine's maximum, really should increase it's max hashsize as I'm getting incomplete PV's at this length of searches because of overwrites.) An hour of analysis.

Re: Crafty 22.8
It is seconds, i dont know why it says 1 second at the fail high(maybe its something with the copying from the scid interface ?)Eelco de Groot wrote:I do not understand all of Crafty's output, I interpret the numbers between brackets as seconds but in the last lines there is a number of 1.04 seconds, if that is for 18 plies that would be very fast even for Crafty

Re: Just another test position
That is much faster than the free Rybka 2n2 version I have - quite an improvement.

Re: Just another test position
Not bad, but it makes me wonder if its a King Safety issue ?
Does Neurosis have King Safety evals ?

Re: Crafty 22.8
Also note that in your output, it found the correct move at depth 17, not depth 18...kiroje wrote:It is seconds, i dont know why it says 1 second at the fail high(maybe its something with the copying from the scid interface ?)Eelco de Groot wrote:I do not understand all of Crafty's output, I interpret the numbers between brackets as seconds but in the last lines there is a number of 1.04 seconds, if that is for 18 plies that would be very fast even for Crafty
