Optimal algorithm in os
WebDec 12, 2024 · There are 10 major types of CPU scheduling algorithms which are discussed in detail ahead. 1. First Come First Serve (FCFS) Scheduling Algorithm The FCFS algorithm is the simplest of scheduling algorithms in OS. This is because the deciding principle behind it is just as its name suggests- on a first come basis. 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 .
