New engine release: Jumbo

Post by Sven » Mon Sep 19, 2016 1:37 pm

Since this is my CCC post #3000 I want to announce my new chess engine "Jumbo" (current version: 0.1.5). As intended, its rating is exactly 3000, of course.
When choosing the right scale.

Download and infos

"Jumbo" played its first online blitz tournament last Saturday on HGM's server. Changes since then were a time control bugfix for conventional TC and some pawn eval improvements.

Future plans include:
- work on usability (configuration, e.g. hash size; book support; analyze mode)
- improve the search
- build two engine variants (twins) where one is using mailbox and the other bitboards, everything else the same
- parameter tuning
- parallel search
- Elo 3001

Thanks Sven! A pity you were not paired against Skipper in the first tournament ;-)

Yes. It would have been the next pairing in round 10, though ...

Yes, but also to KnockOut.
Surprise was released in 2004, KnockOut in 2010, Jumbo in 2016.

Did you write the code from scratch or did you copy from an established engine such as Moron? I seem to recall some dispute between you and Fern about code similarities :?

Seriously, your announcement has caused me for the first time in a awhile to wish that I had an active computer. I would love to run some matches with Jumbo. I am glad to see that you are still active, Sven.

Thanks Sven.

I have a problem, though. Maybe I'm doing something wrong but I have had 75 time forfeits by Jumbo out of 139 games. WinBoard 4.0.8b used under 64-bit Win10.

It may very well be the well-known problem of the engine not counting the moves fed by an external book.
