New engine DesasterArea

[Jochen Peussner]

Hello,
I want to introduce my "new" engine DesasterArea, started in 2011 from scratch to learn more about bitboards. It is a 32-bit windows application using uci-protocol and supporting nearly all uci-options.
Special features:
You can edit and tune many engine-parms, for example you can make DA a pure materialist by setting all parms from pawnstruct to oracle to zero and then try the tactical positions of the old LCTII-Test starting with Nxd6. You will be surprised!
You can switch off all search-enhancements (except move-ordering) and get a basic pvs-search. Of course, by switching off search-trick after search-trick, the engine will (hopefully) get weaker and weaker.
You can download DA from desasterarea.jimdo.com.

Thank you for the new engine, Jochen. It seems to have quite the speculative attacking style. Is there any relation to this program and your old program Neurologic?

[Graham Banks]

Hello,
I want to introduce my "new" engine DesasterArea, started in 2011 from scratch to learn more about bitboards. It is a 32-bit windows application using uci-protocol and supporting nearly all uci-options.
Special features:
You can edit and tune many engine-parms, for example you can make DA a pure materialist by setting all parms from pawnstruct to oracle to zero and then try the tactical positions of the old LCTII-Test starting with Nxd6. You will be surprised!
You can switch off all search-enhancements (except move-ordering) and get a basic pvs-search. Of course, by switching off search-trick after search-trick, the engine will (hopefully) get weaker and weaker.
You can download DA from desasterarea.jimdo.com.

Hi Jochen,

Thanks for sharing your engine with us.

Any special reason for the spelling - DesasterArea as opposed to DisasterArea?

Roughly how strong do you estimate your engine to be?

Regards,
Graham.

[Jochen Peussner]

Hello Tony,
I took only the uci-source from Neurologic. Switching to bitboards was the
chance to make anything different.

[Jochen Peussner]

Hi Graham,
first, the spelling is a typo since the beginning (nomen est omen), I will
change it soon, thanks.
The strength at game in 60 sec is clearly stronger than Fruit 2.1 ( > 140 ELO)
and weaker than Fruit_Reloaded

Thanks. Look forward to trying it out soon!

What hides under the parameter "oracle"?

[menniepals]

By the way, where can I download your engine?

[Jochen Peussner]

It is a set of generell rules. A short description of the params is in the
zip-file.

Hello Alfred:

By the way, where can I download your engine?

The original post contains the URL but for some reason URL tags did not work properly. I repeat the homepage:

http://desasterarea.jimdo.com/

You will find a ZIP of 77.6 KB with the version 1.54 of this engine.

Regards from Spain.
