Taipan 1.0 - an extremely strong chess engine

[supersharp77]

Whatever it is.........someone was doing "private" testing on it back in Oct-Nov 2013......

XXXXXXX

Hi Dann,

I wrote it last weak in the (Jim Ablett) thread.
The next one will be Dann Corbit ...

I missed your messages all the years.
Computer Chess without important persons is often boring.

We call the good Spirits for our hobby.
I am sure, 2015 will be a good year!

Welcome back Dann with many regards from gibberish english expert FAQ, Trier, Germany.

Best
Frank

Mr. Leonard Krylo, you got some 'splainin' to do.

Actually, I don't even want to hear it.

OMG!!

Hi Lukas

How do you know the engine is based on Stockfish ?

Just reading the UCI options shows you the level of incompetence and dishonesty of this troll:

Code: Select all

option name Write Log type check default false

He simply renamed "Write Search Log" option from Stockfish (it was removed recently, but was there in SF 5).

Code: Select all

option name Anger type spin default 0 min -100 max 100

He renamed the "Contempt" option here to "Anger".

Code: Select all

option name Average Split Depth type spin default 0 min 0 max 12

He renamed "Min Split Depth" to "Average Split Depth". Obviously he has not the vaguest clue about how the search works, let alone an SMP search!

Code: Select all

option name Threads type spin default 2 min 1 max 128

He changed the default to 2 threads instead of 1.

Code: Select all

option name Hash type spin default 76 min 1 max 1048576

He changed the default hash to 76 instead of 16. He's such a moron, he doesn't even understand that Hash is anyway rounded down to a power of two.

Code: Select all

option name Nullify Hash type button

He renamed "Clear Hash" into "Nullify Hash". Shows he has no clue about the UCI standard.

Code: Select all

option name MultiPV type spin default 1 min 1 max 500

Same max value as SF, strangely. How many engines use 500 max value for multipv ?

Code: Select all

option name Strength type spin default 200 min 0 max 200

He renamed Skill Level into "Strength" and rescaled it by 10.

Code: Select all

option name Thinking Limit type spin default 30 min 0 max 6000

He renamed "Move Overhead" to "Thinking Time", which shows he doesn't even understand what this option means.

Code: Select all

option name Thinking Time type spin default 35 min 0 max 6000

Renamed "Minimum Thinking Time" to "Thinking Time", which shows he doesn't even understand what the option means. Changed the default value a tiny bit, to pretend to understand what he's doing.

Code: Select all

option name Dull Propeller type spin default 80 min 10 max 1000

He renamed "Slow Mover" to "Dull Propeller", which demonstrates again that he doesn't understnad what this option mean.

Code: Select all

option name FischerRandom type check default false

In a pathetic attempt to obfuscate, he renamed "UCI_Chess960" to "FischerRandom". Unfortunately that won't work and violates the UCI protocol.

Code: Select all

option name Tactical Skill type spin default 50 min 0 max 100

No idea what this is. Considering his level of competence is zero, he's not capable of coding anything in the search. My best guess is that it's a placebo option that does nothing.

Code: Select all

option name Positional Skill type spin default 50 min 0 max 100

Idem. Placebo. Or maybe he added some random crap (which anyone competent would call a bug) to the search or the eval somewhere...

Can someone please delete this thread and ban this troll ?

Thank you!

[Adam Hair]

If possible, you guys should ban him from the Stockfish forum. I believe that he is the Mark Lefler impersonator and the guy who could not compile a Windows binary of SF.

[skoony]

I'm nobody special.

But I am glad to be back. The time was right. I figure it is best to go quietly when you go, and come back quietly when you return.

When you make big announcements about falling on your sword, it always seems funny when you reappear.

hi Dan,
glad your back.

Fabien came back. I have seen Jim Ablett logged into CCC. Dann has started posting again. Whose next? Chris Conkie?

Well damn.

[mcostalba]

Code: Select all

option name Strength type spin default 200 min 0 max 200

He renamed Skill Level into "Strength" and rescaled it by 10.

Well, this one is not bad. Indeed "Strength" or perhaps "Strength Level "seems to me a nicer name than "Skill Level"....perhaps we should adopt it...


Of course re-scaling to 200 is plain wrong and makes no sense: he even didn't bother to check the actual code to realize that there are only 20 real different skill levels among which to choose.


P.S: I think the troll reached his goal: to make people commenting on his post...probably he is even laughing now...although, considering his sad pathology, there is very little to laugh if I were in him.

[lucasart]

Code: Select all

option name Strength type spin default 200 min 0 max 200

He renamed Skill Level into "Strength" and rescaled it by 10.

Well, this one is not bad. Indeed "Strength" or perhaps "Strength Level "seems to me a nicer name than "Skill Level"....perhaps we should adopt it...

Instead, what would be more interesting is to replace this skill level by the standard UCI_LimitStrength and UCI_Elo. We need to do some measure of the skill levels, and come up with a scaling function that translates them into elo and vice versa.
