WebRequirements for Critical-Section Solutions. 1. Mutual Exclusion. If process Pi is executing in its critical section (CS), then no other process can execute in its CS. 2. Progress. WebPeterson's algorithm (or Peterson's solution) is a concurrent programming algorithm for mutual exclusion that allows two or more processes to share a single-use resource without conflict, using only shared memory for communication.It was formulated by Gary L. Peterson in 1981. While Peterson's original formulation worked with only two processes, …
