In this tutorial, we will learn about the SJF i.e., Shortest Job First Scheduling Algorithm with the help of example.ByMonika SharmaLast updated : May 06, 2023 What is Shortest Job First Scheduling Algorithm (SJF)? TheShortest Job Scheduling Algorithmkeeps track of the Burst time of all th...
The Least Slack Time First (LST) algorithm is a dynamic scheduling algorithm and also known as Least Laxity First. It decides the dynamic priority of the task based on slack time; The task having minimum slack time will be considered the highest priority. It is the most suitable algorithm ...
The waiting time is given by the time that each process waits in the ready queue. For a non-preemptive scheduling algorithm, waiting time of each process can be simply calculated as −Waiting Time of any process = Time of admission to CPU Arrival Time...
Shortest Job First AlgorithmIn this scheduling algorithm the process having minimum burst time will execute first.C++ Program for SJF scheduling//Implementation fo SHORTEST JOB FIRST Using C++ #include <iostream> #include <algorithm> using namespace std; int ab; typedef struct schedule { string pro...
This tutorial is for building the algorithm and the corresponding C++ program for the SJF scheduling algorithm.
