WebDespite this, it is a valuable description of solving the critical-section problem. It illustrates some of the complexities involved when designing software that addresses mutual exclusion, progress, and the bounded waiting period of requirements. Peterson's solution is limited to two processes running alternatively between critical sections. Web1. Consider Peterson's algorithm for mutual exclusion between two concurrent processes i and j. The program executed by process is shown below. repeat. flag [i] = true; turn = j; while (P) do no-op; Enter critical section, perform actions, then exit critical section Flag [i] = false; Perform other non-critical section actions.
