Constructing a program from a specification is a long-known general and fundamental problem. Besides its theoretical interest, this question also has practical implications, since...

We present an extension of first-order predicate logic with a novel predicate ‘at t’ meaning intuitively “this term is a variable symbol”. We give simple sequent proof-ru...
Abstract. State-of-the-art proof presentation systems suffer from several deficiencies. First, they simply present the proofs without motivating why the proof is done as it is do...
