0.10/0.13 c initFormula():: the DIMACS p-line indicates a CNF of 3500 variables and 9344 clauses.
0.10/0.13 c parseCNF():: parsing....
0.10/0.13 c parseCNF():: the CNF contains 0 unary clauses.
0.10/0.13 c runParser():: parsing was successful, warming up engines...
0.10/0.13 c find_and_remove_tautogolies():: found and removed 1 tautologies
0.10/0.13 c simplify_formula():: removed 0 tautological, 780 satisfied and 0 duplicate clauses
0.10/0.13 c preprocessing fase I completed:: there are now 3285 free variables and 8564 clauses.
0.10/0.13 c stat :: sign balance is biased by 0.686
0.10/0.13 c shorten_equivalence(): average equivalence length reduced from nan to nan
0.10/0.13 c using 3-SAT heuristics (occurence based diff)
0.10/0.13 c longest clause has size 3
0.10/0.13 c simplify_formula():: removed 0 tautological, 0 satisfied and 27 duplicate clauses

0.10/0.13 c transformTo3SAT():: you gave me 3500 variables and 8577 clauses.
0.10/0.13 c transformTo3SAT():: by the way, the maximal clause length before transformation was 3.
0.10/0.13 c transformTo3SAT():: I will add 0 variables and 0 clauses!
0.10/0.13 c transformTo3SAT():: the transformation yielded 3500 variabels and 8577 clauses.
0.10/0.13 c main():: clause / variable ratio: ( 8577 / 3500 ) = 2.45
0.10/0.13 c longest clause has size 3
