After 3 days of pain, I finally got my first genetic algorithm and physics engine to work

MP4 version: https://chat.is-going-to-rickroll.me/...

What part of is "genetic"?

@Asbetha the lines are the paths of landers that are trying to land on the flat line at a safe speed and angle. The moves they make are the genes of the chromosome.

Kinda feels like if/else lol

Nice! Getting your first GA to work from scratch is really cool.

@Asbetha lol no. Genetic algorithms are a powerful way to search for an optimal answer to something by randomly combining sets of current answer-candidates in ways sort of kinda analogous to how gene combination works inside a cell. You essentially "breed" answer-candidates together to generate better ones and repeat till your candidates actually work well.

Very cool technique, super useful (kinda overshadowed by deep learning these days but yeah).

@RememberMe I know what GA's are. It was just a joke.

@Asbetha oh well, kinda hard to tell.

Isn't this a codingame.com challenge?

@soulevans07 yes. I can’t submit it in this form due to time constraints but I don’t really care :P

Update: got it to find a solution without flooding the search space. It also goes much quicker now.
