0.61/0.63 c main()::
0.61/0.63 c initFormula():: searching for DIMACS p-line....
0.61/0.63 c full lookahead due to high density!
0.61/0.63 c initFormula():: the DIMACS p-line indicates a CNF of 50 variables and 4450 clauses.
0.61/0.63 c parseCNF():: parsing....
0.61/0.63 c parseCNF():: the CNF contains 0 unary clauses.
0.61/0.63 c runParser():: parsing was successful, warming up engines...
0.61/0.63 c simplify_formula():: removed 0 tautological, 0 satisfied and 0 duplicate clauses
0.61/0.63 c preprocessing fase I completed:: there are now 50 free variables and 4450 clauses.
0.61/0.63 c stat :: sign balance is biased by 0.009
0.61/0.63 c shorten_equivalence(): average equivalence length reduced from nan to nan
0.61/0.63 c using k-SAT heuristics (size based diff)
0.61/0.63 c longest clause has size 7
0.61/0.63 c simplify_formula():: removed 0 tautological, 0 satisfied and 2 duplicate clauses
0.61/0.63 c resolvent_look() :: found 2 resolvents
0.61/0.63 c main():: clause / variable ratio: ( 4452 / 50 ) = 89.04
0.61/0.63 c longest clause has size 7
0.61/0.63 c simplify_formula():: removed 0 tautological, 0 satisfied and 0 duplicate clauses
0.61/0.63 c dynamic_preselect_setsize :: off
0.61/0.63 c suggested doublelook initial :: 0
