NaDeA: A Natural Deduction Assistant with a Formalization in Isabelle
We present a new software tool for teaching logic based on natural deduction. Its proof system is formalized in the proof assistant Isabelle such that its definition is very precise. Soundness of the formalization has been proved in Isabelle. The tool is open source software developed in TypeScript / JavaScript and can thus be used directly in a browser without any further installation. Althoug...
متن کاملNatural Deduction and the Isabelle Proof Assistant
Our motivation is that our students should obtain a logical background that give them the prerequisites to build and formally verify dependent software. Building and verifying such software systems can be done in proof assistant computer programs like Isabelle [16] in which natural deduction reasoning is a central concept. Our website therefore forms part of a course which, among other subjects...
متن کاملNovel Didactic Proof Assistant for First-Order Logic Natural Deduction
We present a proof assistant designed to help learning formal proof, particularly in the system of Natural Deduction for First-Order Logic. The assistant handles formulas and derivations containing metavariables and allows to maintain a library of instanciable lemmas. It possesses a graphical interface presenting proofs as trees and handles multiple simultaneous derivations that can be dragged ...
متن کاملPanda: A Proof Assistant in Natural Deduction for All. A Gentzen Style Proof Assistant for Undergraduate Students
We present a proof assistant in Natural Deduction for undergraduate students. The system is interactive: you can combine, delete, modify proofs with a easy-to-use graphical interface. We discuss the pedagogical benefit of this tool.
متن کاملBidirectional Natural Deduction
The goal of this paper is to present a theorem prover able to perform both forward and backward reasoning supported by a well deened formal system. This system for bidirectional reasoning has been proved equivalent to Gentzen's classical system of propositional natural deduction. This paper, primarily aimed at developing a deeper theoretical understanding of bidirectional reasoning, provides ba...
