This tutorial is for building the algorithm and the corresponding C++ program for the SJF scheduling algorithm.
In this tutorial, we will learn about the SJF i.e., Shortest Job First Scheduling Algorithm with the help of example.

Shortest job first is a scheduling algorithm in which the process with the smallest execution time is selected for execution next. Shortest job first can be either preemptive or non-preemptive. Owing to its simple nature, shortest job first is considered optimal. It also reduces the average wai...
Case Study: Interval Scheduling When k = 2, we can solve the given problem with a polynomial time brute-force algorithm. For every set of n2 processes, we loop over m resources to determine if there are any resources in common between them. If they don’t, there are no sets of k =...
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 ...
