Question about posting data comparing Crafty vs Rybka

[vb4]

I have generated some data comparing Crafty to Rybka which shows some considerable differences and wanted to post it here for your thoughts. Since I want the table to be clear and aligned can I just copy a table from Notepad and expect the format to stay aligned? I prefer not to have to retype the data. Bob perhaps when you have had a chance to review this data I would be interested to hear your explanation as to what causes some of the differences in the data.

Thanks,

Les

Can you explain what type of comparison did you do?

Use the [code] and [/code] tags around the piece of text you want to be formatted with a fixed font.

Hi Uri,

Basically I ran 1 EPD position and from that 1 position I generated the 4 way reflections and also all slider positions. My definition of a slider is taking the piece to move and placing it on all legal squares that can also reach the target square. What I have found in looking at the data is what appears to be a very large difference in the number of seconds and total number of moves needed to find the mate move. I will post it this evening when I get home to see if one of you guys can offer an explanation for the differences. I will report which versions of the 2 engines were used in the analysis. I believe the hardware was the same for both engines.

See you later,

Les
