Thanks a lot. Let's assume Mn is the total number of non-resident pages in follow words. Nod, 'M=Mh+Mc' and 'Mc+Mn' < 2M are always true. Have this implied that Mn is alway less than M? I think so. but if "Once the number exceeds M the memory size in number of pages, we terminted the test period of the cold page pointed to by HAND-test." If Mn is alway less than M, when we move to HAND-test? Or, my view have error. I doublt on this, in fact. Good luck.
