E.Goldberg. Determinization of resolution by an algorithm operating on complete assignments. Technical Report CDNL-TR-2007-0106, January 2007
The technical report above replaces  the previous report  on "Determinization of resolution by an algorithm operating on complete assignments". 
The new report contains one more table of results and proves that  the set of points visited by FI is actually a point image of the resolution proof FI builds. 
Note that I use a new definition of the point image that is slightly different from  one used in the SAT-2006 paper and in the previous report mentioned above.

Although the preamble of the paper above says that it was submitted in 2006, in reality it had been in the pipeline of DAM for three years since 2003. This paper is different from our DATE-2002 submission in that every feature of BerkMin is justified experimentally. So you may still find it interesting. I am not allowed to have this paper accessible through my webpage. But I can send it to you by email.

2006

 The slides of 3 lectures I gave at the workshop "Algorithms for the SAT-Problem". Humboldt University, Berlin, October 27-29, 2006. 
 First lecture. Gives some introduction to SAT and some basic knowledge about resolution proof system. Describes DP and DPLL procedures.  
 Second lecture.Describes the interiors of modern resolution based SAT-solvers.
 Third lecture. Introduces formulas with short resolution proofs that can not be found efficiently. Describes testing satisfiability by 
                 computing a stable set of points/clusters.
