It uses maximal munch to scan input tokens in predicate logic, and then uses a modified version of the shunting yard algorithm to generate a parse tree. Then, rules are checked to ensure correct usage ...

We give a constructive proof of McNaughton's theorem stating that every piecewise linear function with integral coefficients is representable by some sentence in the infinite-valued calculus of ...
