Fabio Rojas will present

"Abstract Models of Memory Management," by
Morriset, Felleisen, and Harper


This paper was presented in FPCA 95 and was published as a Technical
Report from the School of Computer Science at Carnegie Mellon
University.

I will present the authors' framework for calculi that make the heap
of a program "syntactically apparent." This approach can be used as
the basis for specifying grabage collection alogrithms and for proving
the correctness of such algorithms. As examples, I will present the
authors's proof for the correctness of trace-based garbage collection,
generational garbage collection, and type-based, tag-free
collection. I will also show how this framework can be used to specify
and prove that type inference can be used to identify objects as
garbage if they are never used but are still accesible.
