Constraints as Processes

Björn Victor and Joachim Parrow

Abstract:

We present a compositional encoding of the gamma-calculus into the pi-calculus. The former, used in the Oz semantics, is a recent small language with equational constraints over logical variables; the latter is a basic calculus of interacting processes. We establish a close correspondence between the reductions in the gamma-calculus and its encoding, using weak barbed bisimulation congruence.
