In this paper we extend the model of program variables from the Refinement Calculus [2] in order to be able to reason more algebraically about recursive procedures with parameter...
Distance semantics is a robust way of handling dynamically evolving and possibly contradictory information. In this paper we show that in many cases distance-based entailments can ...
We present a new approach to dealing with default information based on the theory of belief functions. Our semantic structures, inspired by Adams' -semantics, are epsilon-beli...
