Formal Aspects of Computing

Thirty years ago, at the time that the development of theorem proving software first began, computer technology was far less advanced than it is now. It was still not unknown, for example, for computer programs to be prepared on paper tape, punch cards being ...

The CtCoq user-interface is a graphical user-interface designed to be added to the Coq proof development system, acting as a broker between the human user and the logical engine. The principal design goal for CtCoq was to support large-scale ...

GUI design isn't simply a matter of putting a nice front-end on a capable program. It requires thought about the way in which people might be expected to use a system, and investigation of the ways that they actually use it. Jape's GUI has been ...

We describe an approach to user interface design based on ideas from social science, narratology (the theory of stories), cognitive science, and a new area called algebraic semiotics. Social analysis helps to identify certain roles for users ...

The key to a successful proof often lies within the analysis of failed proof attempts. Motivated by this observation we have developed and evaluated an interface to an inductive theorem prover which supports a collaborative style of failure ...

The capabilities of a automated theorem prover's interface are essential for the effective use of (interactive) proof systems. LΩUI is the multi-modal interface that combines several features: a graphical display of information in a proof graph, ...

We introduce an Emacs interface for writing HOL proof scripts in SML based on the Computing-as-Editing paradigm. Tactics in a proof script are considered as constraints, and the process of interactive theorem proving becomes that of solving ...
