Web8. mar 2014 · In 1981 the most concise version presented for two concurrent processes was Peterson's Algorithm. Peterson used the OR operator in the decision control. Tanenbaum uses a claimed version of Peterson's Algorithm that uses the AND operator in the decision control and there is no resetting of the flags. WebPeterson solution implementation. I'm applying the peterson solution for protecting memory of the critcal section. Each child process should contain a local variable that keeps track of the number of times it interrupts the other child while it is in its critical section. The process should display this value before terminating.
