2018-09-06 21:29:58 +0200 | asked a question | Usage of cryptominisat I am using cryptominisat 5.0. I have a file of DIMACS standard format having a mix of cnf clauses and xor clauses( an “x” in front of the line to make that line an XOR clause). I saved it with filename DIMAC.cnf. I gave this file as input to cryptominisat as follows: solver.read("/home/hridya/SageMath/DIMAC.cnf") I got the following error. ValueError: invalid literal for int() with base 10: 'x1'. What is the problem? |
