A prospective study of the use of ordered multi-lattices as underlying sets of truth-values for a generalised framework of logic programming is presented. Specifically, we investi...
At the beginning stage of programming education, comprehending program logics plays a more important role than capturing knowledge of a specific program language. In this paper, t...
It is possible, but difficult, to reason in Hoare logic about programs which address and modify data structures defined by pointers. The challenge is to approach the simplicity of ...
Permissive-Nominal Logic (PNL) is an extension of firstorder logic where term-formers can bind names in their arguments. This allows for direct axiomatisations with binders, such...
How to extract negative information from programs is an important issue in logic programming. Here we address the problem for functional logic programs, from a proof-theoretic pers...
