FOL tableaux solver

tableaux is a mix project folder. It includes a tableaux based solver for propositional logic + predicates but no quantifiers (so far!) and a TPTP parser for fof and cnf based on yecc and leex. The tableaux file includes two modules, the solver itself and a helper for e.g. timed execution of the solver.

to run the parser/solver:

in the mix project folder run:

    iex -S mix

Then in the elixir command line run:

    x = Parser.parse_TPTP_from_file(<filepath>)
    Tableaux.proof(x)
