The Attributed Pi Calculus


The attributed pi calculus (pi(L)) forms an extension of the pi calculus with attributed processes and attribute dependent synchronization. To ensure flexibility, the calculus is parametrized with the language L which defines possible values of attributes. pi(L) can express polyadic synchronization as in pi@ and thus diverse compartment organizations. A non-deterministic and a stochastic semantics, where rates may depend on attribute values, is introduced. The stochastic semantics is based on continuous time Markov chains. A simulation algorithm is developed which is firmly rooted in this stochastic semantics. Two examples, the movement processes in the phototaxis of Euglena and the cooperative binding in the gene regulation of the lambda Phage, underline the applicability of pi(L) to systems biology.
