A Browsable Format for Proof Presentation

The paper describes a format for presenting proofs called structured calcula tional proof The format resembles calculational proof a style of reasoning popular among computer scientists but extended with structuring facilities A prototype tool has been developed which allows readers to interactively browse proofs presented in this format via the world wide web The ability to browse a proof increases its readability and hence its value as a proof Computers have been used for some time to both construct and check math ematical proofs but using them to enhance the readability of proofs is a relatively novel application This paper was originally presented at the symposium on Logic Mathematics and the Computer The reference is as follows Jim Grundy A browsable format for proof presentation In Christo er Gefwert Pekka Orponen and Jouko Sepp anen editors Logic Mathematics and the Computer Foundations History Philosophy and Applications volume of the Finnish Arti cial Intelligence Society Symposium Series Helsinki June pages
