Overview
Learning outcomes
At the end of the course the student should:
- understand some of the issues and difficulties involved in Concurrency;
- be able to specify and model concuurent systems using CSP;
- be able to reason about CSP models of systems using both algebraic laws and semantic models;
- be able to analyse CSP models of systems using the model checker FDR.
Synopsis
- Processes and observations of processes; point synchronisation, events, alphabets. Sequential processes: prefixing, choice, nondeterminism. Operational semantics; traces; algebraic laws.
- Recursion. Fixed points as a means of explaining recursion; approximation, limits, least fixed points; guardedness and unique fixed points.
- Concurrency. Hiding. Renaming.
- Non-deterministic behaviours, refusals, failures.
- Hiding and divergence, the failures-divergences model.
- Specification and correctness.
- Communication, buffers, sequential composition.
