This is the first book entirely dedicated to the problem of§memory management in programming language implementation.§Its originality stems from the diversity of languages and§approaches presented: functional programming, logic§programming, object oriented programming, and parallel and§sequential programming.§The book contains 29 selected and refereed papers including§3 survey papers, 4 on distributed systems, 4 on parallelism,§4 on functional languages, 3 on logic programming languages,§3 on object oriented languages, 3 on incremental garbage§collection, 2 on improving locality, 2 on massively parallel§architectures, and an invited paper on the thermodynamics of§garbage collection.§The book provides a snapshot of the latest research in the§domain of memory management for high-level programming§language implementations.
