WebJan 21, 2024 · The process in an operating system occupies some dedicated memory. This memory is further divided into chunks called pages. These pages are brought from secondary memory to the primary memory as the CPU demands them. This method is known as page swapping and is done through an algorithm. Optimal Page Replacement … WebIn computer science, an algorithm is said to be asymptotically optimal if, roughly speaking, for large inputs it performs at worst a constant factor (independent of the input size) worse than the best possible algorithm. It is a term commonly encountered in computer science research as a result of widespread use of big-O notation .
