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...

A quicker A * pathfinding algorithm 1. Introduction What means the shortest path? The shortest path is the minimum distance or cost required to go from one point to another in a graph or network. It could mean, the least number of steps, the smallest total weight (cost), the fastest rou...
His algorithm runs in O(n3(loglogn/logn)1/3) time. Fredman's algorithm can also run in O(n2.5) time nonuniformly. Later, Takaoka improved the upper bound for all pairs shortest paths to O(n3(loglogn/logn)1/2) [21]. Dobosiewicz [9] gave an upper ...
Shortest Job First Scheduling algorithm can be both pre-emptive and non pre-emptive. Learn implementations of SJF scheduling algorithm with help of an example.
Klein [4] proposed a dynamical program- ming recursion-based fuzzy algorithm that specified each arc length within an integer value from one to a fixed number. Liu [8] algorithm for finding the shortest path can obtain a non-dominated shortest path. For this, they need to transform all ...
In this paper we show that the problem can be solved in\nlinear time if the distances from $s$ and $t$ to all other vertices are given.\nParticularly our new algorithm runs in $O(|V|\\log |V|+|E|)$ time for general\ngraphs, which improves the previous result of $O(|V|^2)...
Equitable shortest job first: A preemptive scheduling algorithm for soft real-time systems.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...
