Subject: Slow engines

Hi,

  Just wanted to know how many "slow" engines are present in current computer
chess world that are undergoing active development (like the programmer dusting
the code every month or so ;) ) ?
Here , I mean slow by design and not due to lack of good algorithms or
unoptimised code.
  DIEP is one sure for sure , so is mine (messchess).
Any others ?

Basic idea - detailed qsearch , heavy move ordering , big eval , etc.
Stuff that may reduce your nps.

Just to give an objective comparison to differentiate the "slow" from others.
On an athlon 2400xp , for a typical middle game position :

slow engines
Messchess about 40knps.
Diep about 80knps.

moderately fast to fast
tiger about 250knps
crafty 400 knps
fritz about 500 knps

Very fast
Junior about 900 - 1000 knps !! :)


Thanks for the info,

Regards
Mridul

PS : Just because an engine has low nps need not directly translate to poor
chess or low depth :)
