Calculi with explicit substitutions (ES) are widely used in different areas of computer science. Complex systems with ES were developed these last 15 years to capture the good comp...
We describe BE, an implemented system for solving belief change problems in the presence of actions. We illustrate how we can use BE to compute the result of belief progression, be...
Abstract— We present a computational framework for automatic deployment of robots in 2D and 3D rectangular environments with polytopal obstacles. The results are derived for poly...
Hoare logic is bedevilled by complex but coarse side conditions on the use of variables. We define a logic, free of side conditions, which permits more precise statements of a pr...

We give a Natural Deduction formulation of an adaptation of G¨odel’s functional (Dialectica) interpretation to the extraction of (more) efficient programs from (classical) proof...
