What is the reason for Belady's Anamoly
What is the reason for Belady’s Anomaly,I am aware that it is not a stack based algorithm and for a certain set of pages it shows this anomaly where the increase in page frame increases the page fault rate.

Beladys anamoly
"if an algorithm has stack property then it never falls into Beladys Anomaly" Is their any simple proof to this? Also I wanna know if it's one way or two way implication. Thanks.

Basic Optimal page replacement policy doubt.
Consider page references, 1,2,3,5,2,3,4 and number of frames = 3. In the end will the frame contain 4,2,3 or 5,4,3 ?
