Analytic variations on the common subexpression problem,nly once. Such a compaction can be effected in linear time. It is used to save storage in implementations of functional programming languages, as well as in symbolic manipulation and computer algebra systems. In compiling, the compaction problem is known as the “common subexpression problem” and it

Can a maximum flow be computed in ,(,) time?,, this improves the previous best bound of .(..)..The bottleneck in our algorithm is a combinatorial problem on (unweighted) graphs. The number of operations executed on flow variables is .(..(log .).), in contrast with Ω(.) flow operations for all previous algorithms, where . denotes the number of

This establishes the theoretical basis for a powerful and general type hierarchy with static type checking, which enables 1st order polymorphism combined with (multiple) inheritance and specialization in a language with assignments.
