Quantum Job Shop Scheduling Problem Solver
A heuristic approach on how to optimally schedule jobs using a quantum computer.
Publication can be found here.
NOTE: for a more efficient solution check out the \”pyqubo\” branch.
(works extremely slowly while using simulation instead of real qpu.)

About The Project
Note: Numbers in bars represent jobs
Given a set of jobs and a finite number of machines, how should we schedule our jobs
on those machines such that all our jobs are completed at the earliest possible time?
This question is the job shop scheduling problem!
Getting Started
Prerequisites
- python 3.5 or later
- matplotlib (for results visualisation in charts.py)
pip3 install matplotlib
- D\’Wave\’s libraries for interaction with QPU API

Installation
NOTE: If you are okay with using a simulator instead of a real QPU, jump to part 3.
