  • Detailed description:

    This class allows you to parse first order logic formulas. These formulas can be written in any syntax that you define.

    You can apply basic logic operations (and, or, not, implies, etc...).

    You can transform proposition (cleaning, developing, disjunctive form, conjunctive form).

    You can even make demonstrations of your proposition, by looking up the values table or simply by demonstrating it (simple analysis of the disjunctive form: not too greedy).

    The FOLP Checker allows you to prove that a proposition is a theorem, and if it is not, you will be presented a counterexample.

    Karnaugh's table and other nice features will be soon added.

      Plain text file example4.php Example Show cloning feature, and how to set values to variables in a proposition
      Plain text file example5.php Example Shows how you can extend the base class to have nice HTML output of the values table
      Plain text file example6.php Example Shows conjunctive/disjunctive forms of a proposition. You can see here that the computation time is a bit long :(
