Intelligent Algorithm Scheduler

genetic algorithm for Cloud Scheduler:

• simulate.py
• ./schedulers/GAScheduler.py

genetic algorithm for FJSP

• JSSP_executor.py
• ./fjspkits/Genetic4FJSP.py

Introduction

This repository provides two models currently.

1. Solving FJSP using Intelligent Algorithm(Genetic Algorithm), and draw gantt plot.

python ./JSSP_executor.py

2. This project is dedicated to solving cloud computing scheduling problems using intelligent algorithms. It can replace evaluation functions, plot and store results and charts. It should be noted that all are discrete scheduling problems, which means that all particle swarm optimization algorithms are discrete particle swarm optimization algorithms. In addition, the Optimization on Graph and Flexible Job-Shop Scheduling Problem are developing.

python ./simulate.py

└─SchedulerScaleandFitness.py: This file is used to compare the optimal solutions of multiple algorithms and their convergence curves.
└─Schedulers.py: Similar to the above, it includes comparative experiments for different groups.
└─chaosTest.py: Similar to the above, it includes comparative experiments for different groups.

Not every algorithm has a paper, as some are my own improvement attempts.

• GA: Genetic Algorithm

• SA: Simulated Annealing Algorithm

• ACO: Ant Colony Optimization Algorithm

• PSO: Particle Swarm Optimization Algorithm

• CRPSO: Chaotic Hierarchical Gene Replication

• DPSO: discrete PSO

• CDPSO: Chaotic PSO

• TSA: Taboo Search Algorithm

• others

• ChaosDPSO(DPSO based on Chaos)

• ChaosHPSO(DPSO based on Chaos and hierarchical)

• newPSO(modified PSO)

utils/*.py: tools The remaining codes that have not been introduced are utility classes or abandoned code from that year.

Example

python ./JSSP_executor.py

python ./simulate.py
