A Buzz clone, confirmed by Pradu Kannan, author of Buzz.

Oxygen is a private engine, but its "author" has contacts with some well known programmers, therefore I need to make the information public.

My public thanks go to Christopher Conkie, who immediately saw similarities with Buzz when I showed him some strings of Oxygen.

The reason why you see it announced here is because CCC took down the thread for posting the findings. So I guess you won't see any clone alerts from them anymore. Not that you should read it of course.

Now will Robindu please come clean with what he has done. May be we'll forgive him when he writes his own engine and not doing a second clone like the another person I heard about which I don't want to mention by name.

This is the FEN parsing comparison. Some important highlights are that the error and parsing order in Oxygen and Buzz are exactly the same and also that some non-standard FENs are accepted (incomplete FENs, 'd' to represent 'b' in the color to move data). Of course, this alone is not enough for a clone accusation, and will work on posting writing up more comparisons (eg starting-stopping of 3 threads in search, html log file code...).

Code: Select all: FEN parsing similarity ====================== Buzz's error/parsing order: 1) No piece placement data 2) No active color data 3) Exceeding 8 squares per rank with non-numeric 4) Unrecognized charecter 5) Active color parsed b, B, d, or D -> black otherwise white 6) Castling availability, recognized charecters added 7) Legality Testing a) No kings for White b) No kings for Black c) Too many kings for white d) Too many kings for black e) Side to move is in check f) Pawns on the first rank g) Pawns on the eighth rank Parser can also handle incomplete FENs ----------------------------------------------------------------------- Test 1: Handling Incomplete FENs ----------------------------------------------------------------------- This test identifies the parser's capability to handle incomplete FENs.

Code: Select all: Search Threading Comparison Test ================================ During search Buzz uses three threads: 1) Input Thread This takes care of winboard/xboard commands. 2) Search Thread This thread will do a tree search on the current position. 3) Search Monitor Thread This thread will monitor the search thread. Before a search starts there is only one thread running, the input thread. When the input thread is given a command or if there is an implied command to start the search thread, the input thread will create a Search Monitor Thread. The Search Monitor Thread will launch Search Threads and will be responsible for monitoring the Search Thread and its termination. When the engine is not searching there should be only one thread active. When the engine is searching two threads will be active with another thread being spawned and destroyed for each ply.

Code: Select all: Oxygen 0.10 =========== Oxygen 0.10 (a previous version) seems to be a Witz clone. The following are strings found with IDA Pro: _RDATA:00E0335C 0000000E C PASSEDPAWNPST _RDATA:00E0336C 00000012 C HALFPASSEDPAWNPST _RDATA:00E03380 0000000F C DOUBLEDPAWNPST _RDATA:00E03390 00000010 C ISOLATEDPAWNPST _RDATA:00E033A0 00000015 C NOTDEFENDABLEPAWNPST _RDATA:00E033B8 0000000E C KS_SCALESTART _RDATA:00E033C8 0000000C C KS_SCALEEND _RDATA:00E033D4 0000000B C SEARCHTYPE _RDATA:00E033E0 0000000E C CHECKEVASIONS _RDATA:00E033F0 00000014 C RECAPTUREEXTENSIONS _RDATA:00E03404 00000008 C USECook _RDATA:00E0340C 00000011 C CookPATHRELATIVE _RDATA:00E03420 0000000B C %*s %*s %s _RDATA:00E0342C 00000009 C CookPATH _RDATA:00E03438 0000000C C GAMESWEIGHT _RDATA:00E03444 0000000B C WINSWEIGHT _RDATA:00E03450 00000006 C ICSPV All of these strings appear in Witz's ini file. (with Book instead of Cook) Also the following Oxygen 0.10 contains strings which are exactly the same strings used in Witz for dumping/loading hashtables to/from a file: _RDATA:00E034D8 0000001D C Unable to open dump file %s\n _RDATA:00E034F8 0000000C C Loaded %s\n\n

Hello Everybody,

First of all let me start with an apology,

I am very sorry for what happened.

I admit that Oxygen was based upon Buzz,I had added some code & eval additions. it was <10% IMO

I just wanted to see how it really worked.

I guess it would have been good if It was presented that way from the start.

I apologize for that to all.

I just want to move on,really...

As I had stated,I really am in the process of writing an engine from scratch.Code writing will soon start.

& for obvious reasons it will be open source.

again the whole purpose of "Oxygen" was to test if my ideas would work.

I was scared,of my actions & what i would have to face.but i realize that i made the mistake,i must face it.

Again I am very very sorry.

to forgive or not is entirely upto you.

I admit my guilt,it was my mistake.

Apologies,
Robindu

After such a clear apology, you just have to move on, and are welcome in this our community :wink:

Note that all we want are stable engines, strength does not matter.

Matthias.
