Re: Paper "Singular Extensions" by Anantharaman, C

[ ... ] If that fails, I checked and I do have a copy of the ICCA Journal, Volume 11 N0. 4 December 1988. But the problem is I do have a scanner which my brother in law gave me once, but it may be broken or have some sort of parallel interface I can't use anymore. It would be easier to make carbon ...

Re: Paper "Singular Extensions" by Anantharaman, C

As an option just search the SE topic, there are very good posts by Bob and others here. All right here for example. http://www.talkchess.com/forum/viewtopic.php?t=35603&highlight=singular+extension I already had a look at several respective posts (thanks!), and as well at an excellent paper by Mar...

Re: Paper "Singular Extensions" by Anantharaman, C

Hi, I'm looking for the classical publication "Singular Extensions: Adding Selectivity to Brute-Force Searching" by Anantharaman, Campbell, and Hsu (1988). Unfortunately, I don't have easy access to the Proceedings / Journal in which this seminal paper originally appeared, and I have not been able ...

Re: Paper "Singular Extensions" by Anantharaman, C

I believe I found it: http://www.sciencedirect.com/science/article/pii/0004370290900739 not so cheap :( :( Downloading source code of Stockfish is cheaper. It implements singular extensions, but perhaps no one understands why it works (in Stockfish) or it is kept a secret. [Singular extensions in m...

Re: Any engine?

Rd2 is suggested by some engines (engine: Fischerle 0.9.50 64 Bit), and, in fact, doesn't look too bad: L1: -2175 ♖d1x♝d3 ♟c4x♖d3 ♕a6x♟d3 L2: -2175 ♖d1x♝d3 ♟c4x♖d3 ♕a6x♟d3 L3: -2409 ♖d1x♝d3 ♟c4x♖d3 ♘...

Re: Engines can't solve this puzzle (even not Stockfish 5)

Not exactly. Strong engines also have extensions so 36 plies can mean more than 36 plies in the longest selected branches. Sure. Typically, the search depth reported by an engine represents a "base" search depth which, however, is variation-locally modified by numerous extensions and reductions as ...
