In short: 
The SAT solver that looks for glue clauses

Glucose is based on a new scoring scheme (well, not so new now) for the clause learning mechanism, based our IJCAI'09 paper. This page summarizes the techniques embedded in the competition 09 version of glucose. Solver's name is a contraction of the concept of "glue clauses", a particular kind of clauses that glucose detects and preserves during search. Glucose is heavily based on Minisat, so please do cite Minisat also if you want to cite Glucose.
