Goal

Draw a line for each car, which represents the driven path.
Probably it would be good if it has some transparency and is also restricted to the last x-frames (not the whole path)

Current State

Nothing like this in place, yet.

Hints / Notes

Goal

There can't be a race without a race track/course, right?

It would be good to have some kind of generator, that creates some random racetracks.
For a first version, it would be fine enough, if it's just an ellipse with some additional curves or something like this.
Later the cars will measure the distance of their position to the border of the track and will collide with the border. This might also have an impact on the design concept of representing the track, e.g. some kind of polygon representation for easier collision detection,... ?

Requirements:

• closed/looped track
• random shape
• no crossings and roads may not touch each other
• some kind of start/finish line

Something like this:

The affine transformation of the cars in PopulationDrawer#drawCar() doesn't seem to be correct.
The center of the car body (rectangle) isn't at the exact car position (car.x, car.y).

It's not a major bug, because it's not affecting anything so far. It just looks strange especially during collision.

Goal

Save the neural network of the best car.
The network should be saved as JSON object.
Has to be triggered for example after each iteration or by an UI event. (see #6 )

Current State

Nothing in place.

Hints / Notes

Goal

Load a neural network, which was saved by #7 earlier and apply it to all cars.
Has to be triggered for example by an UI event. (see #6 )

Current State

Nothing in place.

Hints / Notes

Goal

Implement some interactive functionality to the project, e.g.

• show only best car, hide others
• change (increase/decrease/toggle) mutation rate
• add trace for each car, which visualizes the driven path (requires trace feature #4)
• use neural network of best car for all other cars
• save neural network of current best car (requires save feature #7)
• load neural network (requires load feature #8)

Current State

Nothing in place.

Hints / Notes

Some kind of Key Listener and/or UI would be good (buttons).
