We present a (the rst?) sound and relatively complete Hoare logic for a simple imperative programming language including mutually recursive procedures with call-by-value parameters...
A formula in first-order logic can be viewed as a tree, with a logical connective at each node, and a knowledge base can be viewed as a tree whose root is a conjunction. Markov l...
Abstract. Polytypic functions have mainly been studied in the context of functional programming languages. In that setting, applications of polytypism include elegant treatments of...
The approach to reasoning about structural operational semantics style specifications supported by the Abella system is discussed. This approach uses -tree syntax to treat object ...
This paper investigates fitness sharing in genetic programming. Implicit fitness sharing is applied to populations of programs. Three treatments are compared: raw fitness, pure fi...
