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 (SJ
The Shortest Job First algorithm gives the optimal average turnaround time for a set of processes, but it suffers from starvation for long processes. Starvation occurs when a long process is denied processor resources because the resources are occupied by short processes, thus, causing the long ...

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...

This tutorial is for building the algorithm and the corresponding C++ program for the SJF scheduling algorithm.

Apply the same algorithm again until the priority queue is empty. Implementation: Assume the source vertex =1. #defineSIZE100000+1vector<pair<int,int>>v[SIZE];// each vertex has all the connected vertices with the edges weightsintdist[SIZE];boolvis[SIZE];voiddijkstra(){// set the vertices...

The process which has the least processing time remaining is executed first. As it is a preemptive type of schedule, it is claimed to be better than SJF scheduling Algorithm.SRTF Algorithm ExampleLet's understand this with the help of an example....
