With the book "An Introduction to Optimization Algorithms" we try to develop an accessible and easy-to-read introduction to optimization, optimization algorithms, and, in particular, metaheuristics. We will do this by first building a general framework structure for optimization problems. We then approach the algorithms that have been developed to solve such problems from bottom-up, starting with simple approaches and step-by-step moving to more advanced methods. These moves are incremental, as problems of the current algorithm are discussed based on real results on a real example application, the Job Shop Scheduling Problem (JSSP).
If you have any comments or suggestions regarding the book, or if you spotted an error or typo, please feel free to submit an issue here. Your feedback would help us to improve the book.
The book "An Introduction to Optimization Algorithms" is available in the following formats:
The latter two formats are still a bit experimental, so they might not be beautiful. The html version of the book is fairly large, as it is a single stand-alone file.
Every algorithm that we discuss is implemented in Java 1.8 and all accompanying sources codes are provided in the GitHub repository aitoa-code. This means that you can run the same experiments that I did, but also do your own experiments and use the code for your own purposes. The code provides comprehensive facilities for logging and evaluating experimental results. It should be applicable to a wide range of scenarios. In particular, we tried to make it suitable for scientific experiments and provide built-in experiment execution, parallelization, distribution, and self-documenting output facilities. The code comes as a Maven project that can be integrated as library into your own software, as discussed here.
The final goal is to use this book as the foundation of a university course "Optimization Algorithms." Therefore, I am also trying to create a corresponding set of slides. The book is far from being complete, but the slides are even in a much earlier state of development. Only the first few topics from the book are covered as of now.
Modules marked with "★" can be taught at any point after the Stochastic Hill Climbing module.
The LaTeX source code of the slides is provided in this repository.
It also includes all figures as
A tar.xz archive with everything put together, i.e., the book, the source codes, and the slides, can be found here. We package everything as tar.xz because this format tends to achieve the best compression ratio.
Furthermore, many of the diagrams in this book are generated using an
R package, which is published in the GitHub Repository aitoaEvaluate.
You can install and use it in
The data from the experiments presented in the book is presented in the GitHub Repository aitoa-data.
jsspInstancesAndResults is an repository with lots of results from literature on the Job Shop Scheduling Problem (JSSP).
At the same time, it is also an
You can use it to compare your own JSSP research with the state-of-the-art.
Around this book I have created a whole ecosystem of tools that help me by automating many of work involved in its development. The goal is to allow an author to fully concentrate on writing her material, while compiling the material to different formats and uploading them to the web should be automated. This tool suite is centered around GitHub and putting all material into a repository, which automatically allows for collaborative working as well.
R package bookbuildeR provides the commands wrapping around pandoc and extending Markdown to automatically build electronic books.
There is a hierarchy of docker containers that forms the infrastructure for the automated builds:
beamer-based LaTeX slides to pdf and upload them. Here you can find it on GitHub and here on docker hub.
Rpackage utilizeR holds some utility methods used by bookbuildeR.
Besides these containers, we also have some tools to make our work more efficiently.
ultraSvgz combines several existing pieces (such as
ultraGzip) of software to compile an

This, in turn, makes it easier to keep the total size of the git repositories with our book and slides small.
