One of the keys to the success of the Thousands of Problems for Theorem Provers (TPTP) problem library and related infrastructure is the consistent use of the TPTP language. This p...
We develop an Answer Set Programming formalism based on Default Logic. We show that computing generating sets of extensions in this formalism captures all ΣP 2 search problems.
The HOL system is an LCF-style mechanized proof-assistant for conducting proofs in higher order logic. This paper discusses a proposal to extend the primitive basis of the logic un...
We give a brief account of some de Finetti style representation theorems for probability functions satisfying Spectrum Exchangeability in Polyadic Inductive Logic, together with ap...
The choice construct (choose x : '(x)) is useful in software speci cations. We study extensions of rst-order logic with the choice construct. We prove some results about Hilb...
