CCS (Calculus of Communicating Systems)

CCS (Calculus of Communicating Systems) is a formal framework used to model and analyze how concurrent, interacting processes (or systems) communicate and work together. It provides a set of mathematical tools to specify individual processes and their communication patterns, enabling precise reasoning about system behavior, synchronization, and potential issues like deadlocks. CCS is fundamental in understanding complex, distributed systems, ensuring they function correctly when multiple processes operate simultaneously and exchange information in predictable ways.
