OS Galvin - Doubt
Strangely, if we let $S^R$ be the reverse of a reference string S, then the page-fault rate for the OPT algorithm on S is the same as the page-fault rate for the OPT algorithm on $S^R$ . Similarly, the page-fault rate for the LRU algorithm on S is the same as ... time, rather than forward." So, shouldn't it be: page-fault-rate(OPT($S$)) = page-fault-rate(LRU($S^R$)) ???
