This browser-based 2D car simulation uses a genetic algorithm, according to the Genetic Cars 2 page title.

About Genetic Cars 2

Genetic Cars 2 is a browser-based HTML5 simulation that uses a simple genetic algorithm to evolve random two-wheeled shapes into cars over generations. It is loosely based on BoxCar2D and uses the box2d physics engine. Users can set a seed to create a track, adjust mutation rate and mutation size, choose elite clones, select gravity settings such as Earth or Moon, and use a fixed or mutable floor. Populations can be saved locally and restored, and a replay option shows the top-performing car. The page notes that the simulation is not fully deterministic, so a best car may not perform as well as it once did, and that refreshing the page may help if scripts seem not to have loaded.

Key features

Evolves two-wheeled car shapes over generations with a genetic algorithm
Creates a track from a seed; the same seed produces the same track
Adjusts mutation rate, mutation size and number of elite clones
Offers gravity settings including Earth, Moon, Jupiter and others
Saves and restores populations locally in the browser
Pauses the simulation to replay the top-performing car

Best for: People curious about genetic algorithms who want a visual, browser-based simulation with adjustable evolution settings.

Good for

Runs in a browser and recommends Chrome
Exposes genetic algorithm parameters such as mutation rate, mutation size and elite clones
Seed-based tracks can be shared so users can agree on a seed and compete
