Deciding if mutual exclusion and progress is satisfied
Consider the following Process Pi while(1) { while(turn != i); //critical section turn = j; //remainder section } Process Pj while(1) { while(turn != j); //critical section turn = I; //remainder ... & progress are not satisfied Only mutual exclusion is satisfied Only progress is satisfied Both mutual exclusion and progress are satisfied
