Abstraction, refinement and proof for probabilistic systems

Description

Provides an integrated coverage of random/probabilistic algorithms, assertion-based program reasoning, and refinement programming models, providing a focused survey on probabilistic program semantics. This book illustrates, by examples, the typical steps necessary to build a mathematical model of any programming paradigm. Abstract: Illustrates by example the typical steps necessary in computer science to build a mathematical model of any programming paradigm .Presents results of a large and integrated body of research in the area of 'quantitative' program logics.  Read more...
