logical diagrams (alpha graphs, Begriffsschrift), Polish notation, truth tables, normal forms (CNF, DNF), Quine-McCluskey and other optimizations.

Some of the solver algorithms output the suitable values, but some do not, or output a partial set. It may also happen that the formula is false for all possible values of variables: if so, the solver algorithms report that after exhausting the search options. For example, (a -> b) & a & -b is always false.

Just like a mathematical calculator, the logic calculator allows its users to compute results from various inputs. The inputs in this case are the logical ...

Some (importable) sample proofs in the "plain" notation are here. Note that proofs can also be exported in "pretty print" notation (with unicode logic symbols) or LaTeX. See this pdf for an example of how Fitch proofs typeset in LaTeX look. To typeset these proofs you will need Johann Klüwer's fitch.sty.
