Publisher's Synopsis
There are new implementations of most of the major programming systems in this revised book, including the interpreters and compilers, and the authors have incorporated many small changes that reflect their experience teaching the computer science course at MIT since the first edition was published.;A new theme has been introduced that emphasizes the central role played by different approaches to dealing with time in computational models: objects with state, concurrent programming, functional programming and lazy evaluation, and nondeterministic programming. There are new example sections on higher-order procedures in graphics and on applications of stream processing in numerical programming, and many exercises.;In addition, all the programmes have been reworked to run in any Scheme implementation that adheres to the IEEE standard.
