Solving satisfiability problems using elliptic approximations. A note on volumes and weights
In this note we propose to use the volume of elliptic approximations of satisfiability problems as a measure for computing weighting coefficients of clauses of different lengths. For random 3-SAT formula it is confirmed experimentally that, when applied in a DPLL algorithm with a branching strategy that is based on the ellipsoids as well, the weight deduced yields better results than the weights that are used in previous studies.
