Introduction

  


    Scheduling is a fundamental function of operating systems, and CPU scheduling plays a crucial role in resource utilization and system performance.

    The CPU Schedulers Simulator is a Java program that simulates various CPU scheduling algorithms.

    This project aims to provide a better understanding of different scheduling algorithms and their impact on process execution.

  


  
Implemented Algorithms

  


    The simulator currently implements the following CPU scheduling algorithms:

  

  


    
Non-Preemptive Shortest-Job First (SJF) with context switching

    
Shortest-Remaining Time First (SRTF) Scheduling with starvation prevention

    
Non-preemptive Priority Scheduling with starvation prevention

    


      AG Scheduling:

      


        
Round Robin (RR) Scheduling with AG-Factor

        
AG-Factor calculation based on a combination of priority, arrival time, burst time, and a random function

        
Preemptive and non-preemptive scheduling based on AG-Factor

      

    

  


  
Graphical User Interface

  


    The simulator features a graphical user interface (GUI) that provides a Simple visual representation of the process execution order.

  


  
Project Overview

  


    The CPU Schedulers Simulator allows you to input the necessary parameters for the simulation.

    These parameters include the number of processes, time quantum for round-robin scheduling, and context switching time.

    For each process, you provide the following details:

  

  


    
Process Name

    
Process Color (for graphical representation)

    
Process Arrival Time

    
Process Burst Time

    
Process Priority Number (for priority scheduling)

  

  


    The simulator outputs the execution order of processes, waiting times, turnaround times, average waiting time, average turnaround time,

    and history updates of quantum time for AG Scheduling.

    Additionally, it generates a graphical representation of the process execution order.

  


  
Usage
