Training The Car to Do Self-parking using A Genetic Algorithm

🧬 Self-Parking Car Evolution

Training the car to do self-parking using a genetic algorithm.

Self-Parking Car Evolution

This is an experimental project with the aim to learn the basics of how genetic algorithm works by teaching the cars to do the self-parking. The evolution process is happening directly in the browser. You may check the evolution source-code (in TypeScript) or read the explanation of how it works in my blog-post.

At the beginning of the evolution the generation of cars has random genomes which make them behave something like this:

Self-parking cars at the beginning of the evolution

On the 40th generation the cars start learning what the self-parking is and start getting closer to the parking spot (although hitting the other cars along the way):

Self-parking car in

Another example with a bit more challenging starting point:

Self-parking car in

Genetic Source-Code

The ≈92% of the code in this repository relates to the UI logic (3D simulation of the cars world, form controls for the evolution training process, etc.).

However, the actual code that implements a genetic algorithm takes less than <500 lines of code.

Development Details

The project is a React application written on TypeScript. Styled with BaseWeb.

The 3D world simulation is made with Three.js library using @react-three/fiber wrapper. The physics is simulated with Cannon.js using cannon-es wrapper.

The whole evolution simulation is happening directly in the browser.

To launch the project, fork/clone it and run the following commands:

npm installnpm run start

The website will be available on http://localhost:3000/self-parking-car-evolution.

Hints:

  • You may upload one of the pre-trained checkpoints to avoid starting the evolution from scratch.
  • Use the ?debug=true URL param to see the FPS performance monitor and debugging logs in the console (i.e. http://localhost:3000/self-parking-car-evolution?debug=true).
  • Training progress is being saved to the local storage for each generation (not for each batch/group).

Creating Winning Car Dealer Websites

When a developer creates a car dealer website, he needs to keep several things in mind. Instead of following a generic template to build a car dealer website, a developer should take an in-depth overview of the purpose of the website and create it accordingly.

The top kinds of car dealer websites include car dealer inventory website and used car dealer website, and a developer needs to go ahead with car dealer website design accordingly.

Car Dealer Website

So car dealer website development should be conducted according to the template and the range of options available before a developer should not overwhelm a developer. There are nevertheless some best design practices that work for all car dealer websites. They create winning websites and deliver a matchless first impression.

Just as an instance, navigation tools should be made to be eye-catching and the CTAs should be innovatively placed at a familiar location. They may be made static. Using the best practices, a developer should be able to come up with a matchless WordPress car dealer website. While being oriented towards the end-user, the website should simplify the dealership experience as well.

Adding in functionalities within car dealer website

A car dealership website is likely to require a range of add-in functionalities for simplifying its use and delivering value. This may be accomplished through coding or seamlessly integrating third-party software.

Just as an instance, a visitor should be able to search among the options available easily, based upon parameters such as petrol-driven or diesel driven, make, model, MRP, and savings. Cross search should be enabled. Similarly, if a visitor can compare two cars he likes, it boosts the odds of conversion. A clear idea of pricing and financial information will further enhance the odds of making a purchase and makes it easier for a consumer to find the best deal.

Placing the CTAs right also helps with the same. 360-degree images, magnifying glass, personalized suggestions, and product description further delivers value to search. Over 30% of visitors to your website will use the search functionality.

Car dealer responsive website

A dealer should come up with a fully responsive car dealer website because most of the visitors will view and use the website over their mobile devices. Other features that a car dealer website should have include pricing and finance calculators, ease of finding limited-time offers, friction-free forms, and easy to add reviews and testimonials. Professional car dealer website providers will be in the best position to create a winning Auto dealer websites for your enterprise.

Why Use WordPress? What Can You Do With WordPress?

Can you use WordPress for anything other than blogging? To your surprise, yes. WordPress is more than just a blogging tool, and it has helped thousands of websites and web applications to thrive. The use of WordPress powers around 40% of online projects, and today in our blog, we would visit some amazing uses of WordPress other than blogging.
What Is The Use Of WordPress?

WordPress is the most popular website platform in the world. It is the first choice of businesses that want to set a feature-rich and dynamic Content Management System. So, if you ask what WordPress is used for, the answer is – everything. It is a super-flexible, feature-rich and secure platform that offers everything to build unique websites and applications. Let’s start knowing them:

1. Multiple Websites Under A Single Installation
WordPress Multisite allows you to develop multiple sites from a single WordPress installation. You can download WordPress and start building websites you want to launch under a single server. Literally speaking, you can handle hundreds of sites from one single dashboard, which now needs applause.
It is a highly efficient platform that allows you to easily run several websites under the same login credentials. One of the best things about WordPress is the themes it has to offer. You can simply download them and plugin for various sites and save space on sites without losing their speed.

2. WordPress Social Network
WordPress can be used for high-end projects such as Social Media Network. If you don’t have the money and patience to hire a coder and invest months in building a feature-rich social media site, go for WordPress. It is one of the most amazing uses of WordPress. Its stunning CMS is unbeatable. And you can build sites as good as Facebook or Reddit etc. It can just make the process a lot easier.
To set up a social media network, you would have to download a WordPress Plugin called BuddyPress. It would allow you to connect a community page with ease and would provide all the necessary features of a community or social media. It has direct messaging, activity stream, user groups, extended profiles, and so much more. You just have to download and configure it.
If BuddyPress doesn’t meet all your needs, don’t give up on your dreams. You can try out WP Symposium or PeepSo. There are also several themes you can use to build a social network.

3. Create A Forum For Your Brand’s Community
Communities are very important for your business. They help you stay in constant connection with your users and consumers. And allow you to turn them into a loyal customer base. Meanwhile, there are many good technologies that can be used for building a community page – the good old WordPress is still the best.
It is the best community development technology. If you want to build your online community, you need to consider all the amazing features you get with WordPress. Plugins such as BB Press is an open-source, template-driven PHP/ MySQL forum software. It is very simple and doesn’t hamper the experience of the website.
Other tools such as wpFoRo and Asgaros Forum are equally good for creating a community blog. They are lightweight tools that are easy to manage and integrate with your WordPress site easily. However, there is only one tiny problem; you need to have some technical knowledge to build a WordPress Community blog page.

4. Shortcodes
Since we gave you a problem in the previous section, we would also give you a perfect solution for it. You might not know to code, but you have shortcodes. Shortcodes help you execute functions without having to code. It is an easy way to build an amazing website, add new features, customize plugins easily. They are short lines of code, and rather than memorizing multiple lines; you can have zero technical knowledge and start building a feature-rich website or application.
There are also plugins like Shortcoder, Shortcodes Ultimate, and the Basics available on WordPress that can be used, and you would not even have to remember the shortcodes.

5. Build Online Stores
If you still think about why to use WordPress, use it to build an online store. You can start selling your goods online and start selling. It is an affordable technology that helps you build a feature-rich eCommerce store with WordPress.
WooCommerce is an extension of WordPress and is one of the most used eCommerce solutions. WooCommerce holds a 28% share of the global market and is one of the best ways to set up an online store. It allows you to build user-friendly and professional online stores and has thousands of free and paid extensions. Moreover as an open-source platform, and you don’t have to pay for the license.
Apart from WooCommerce, there are Easy Digital Downloads, iThemes Exchange, Shopify eCommerce plugin, and so much more available.

6. Security Features
WordPress takes security very seriously. It offers tons of external solutions that help you in safeguarding your WordPress site. While there is no way to ensure 100% security, it provides regular updates with security patches and provides several plugins to help with backups, two-factor authorization, and more.
By choosing hosting providers like WP Engine, you can improve the security of the website. It helps in threat detection, manage patching and updates, and internal security audits for the customers, and so much more.

Introduction to Genetic Algorithm

What is Optimization?

  • Making something better.
  • Increase efficiency.

Optimization problem

  • A problem in which we have to find the values of inputs (also called solutions or decision variables) from all possible inputs in such a way that we get the “best” output values.
  • Definition of “best”- Finding the values of inputs that result in a maximum or minimum of a function called the objective function.
  • There can be multiple objective functions as well (depends on the problem).

Optimization algorithm

An algorithm used to solve an optimization problem is called an optimization algorithm.

Evolutionary Algorithms

Algorithms that simulate physical and/or biological behavior in nature to solve optimization problems.

Genetic Algorithm (GA)

  • It is a subset of evolutionary algorithms that simulates/models Genetics and Evolution (biological behavior) to optimize a highly complex function.
  • A highly complex function can be:
  • 1. Very difficult to model mathematically.
  • 2. Computationally expensive to solve. Eg. NP-hard problems.
  • 3. Involves a large number of parameters.

Background of GA

  • Introduced by Prof. John Holland in 1965.
  • The first article on GA was published in 1975.
  • GA is based on two fundamental biological processes:
  • 1. Genetics (by G.J. Mendel in 1865): It is the branch of biology that deals with the study of genes, gene variation, and heredity.
  • 2. Evolution (by C. Darwin in 1875): It is the process by which the population of organisms changes over generations.

Natural selection in Evolution

  1. A population of individuals exists in an environment with limited resources.
  2. Competition for those resources causes the selection of those fitter individuals that are better adapted to the environment.
  3. These individuals act as seeds for the generation of new individuals through recombination and mutation.
  4. Evolved new individuals act as initial population and Steps 1 to 3 are repeated.

Nature-GA Analogy

Structure of GA

GA vs Traditional Algorithms

Applications of GA

  • 1. Acoustics
  • 2. Aerospace Engineering
  • 3. Financial Markets
  • 4. Geophysics
  • 5. Materials Engineering
  • 6. Routing and Scheduling
  • 7. Systems Engineering

Problems with GA

  • 1. Population Selection Problem
  • 2. Defining Fitness Function
  • 3. Premature or rapid convergence of GA
  • 4. Convergence to Local Optima
