Assistant for generating NaturalDeduction style proofs
This application aids in the creation of NaturalDeduction style logical proofs. The style is that used in University of Auckland Philosophy courses.
Upon inputting a sequent, a proof can be completed within NaturalDeduction Planner. The result can be exported to png, to text or to LaTeX macros.
Superficially, Dominoes on Acid is a solitaire variant of Dominoes with weird colorful tiles. But on a deeper level it is a GUI for naturaldeduction. Every completed domino is equivalent to a proof of a tautology in classical propositional logic.
