Answer / pravin tripathi
optimal page replacement algorithm seems to be the best page
replacement algorithm as"the no. of page faults are minimum
as compared to any page replacement algorithm as well as it
is free from belady's anomaly",but the problem is that,it is
very difficult to implement as it need the future knowledge
of reference string.
while least-recently-used(LRU)algorithm is also free
from belady's anamoly and the no. of page faults are fewer
than any other page repl. algorithm(besides OPT algorithm)
it is easy to implement.and is the best page replacement
algorithm.

Answer / scandal
Optimal page replacement algorithm.
Bcoz it overcomes the belady's anomaly;
number of page fault is low.

Answer / dorathy
Optimal algorithm is the best... It has fewer page faults and avoids beladys anamolies..

Answer / tauqeer sahi
Optimal is best but impossible to implement..
There are other good algorithms too but outcome of any algorithm totally depends upon type of input string of pages.
