Research ArticleOpen accessSemantics of Lazy Evaluation using the Two-Level GrammarMahmoud A. AbouGhaly, Sameh S. Daoud, Azza A. Taha, Salwa M. AlyWe have formalized the semantics of lazy evaluation for the lambda calculus using the two-level grammar formalism. The resulting semantics enjoys several properties, e.g., there is a sharing in the recursive computation, there is no α conversion, the heap is automatically reclaimed, an attempt to evaluate an argument is done at most once and there is a sharing in the … …Journal of Computer Science, Vol. 4, Issue 1 · 31 Jan 2008 · 6,755 accessesView PDFCite
Research ArticleOpen accessOperational Semantics for Lazy EvaluationMahmoud A. Abou Ghaly, Sameh S. Daoud, Azza A. Taha, Salwa M. AlyAn operational semantics for lazy evaluation of a calculus without higher order functions was defined. Although it optimizes many aspects of implementation, e.g. there is a sharing in the recursive computation, there is no α conversion, the heap is automatically reclaimed, and an attempt to evaluate an argument is done at most once. It is still suitable for reasoning about … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 6,705 accessesView PDFCite
