AI Battle Royale of 100 SNAKES in C++ - SFML Gamedev - Devlog 

Love it

Next video idea a street fighter clone

@@teriu Agreed, I would love to see that

I wonder how well would the snakes perform with 2 hidden layers(or a cascaded hidden layer where each node receives from all previous nodes in its layer, computed sequentially). I mean, Chrispresso and 1 other guy managed to completely win Snakes with it, so imagine having them in a battle royale...

I just noticed that the video is new, I watched it about 2 Times and I recommend putting a path finding algorithm in one o the snakes than see the result😶

Just 13 minutes and 15 seconds left :(

where, when

Lol I guess the heads shouldn't also convert into food, that way the number of food + body segments is conserved

@@The_Dr_Fate when dying snakes were set to turn into food

@@revimfadli4666 l agree

From my experience, increasing the number of inputs makes them perform worse. Maybe I'm wrong though.

@@Kofybrek Because genetic algorithm can't handle it... (deep) Q-learning should do the trick though if you take the time to build an AI with it

@@Kofybrek Also, one question about the genetic algorithm you used: did you actually set some weights to have new random values during mutation or did you add gaussian noise to them like a sane person?

@@barni_7762 ...I just set a new random value.

@@Kofybrek Lol ok I'm surprised it converged that well... I'm not an expert at this topic but my reasoning is that you want your policy (ai) to converge to a good policy, and when your policy is already not too bad, adding some small random values to a few parameters might bring it closer to where those parameters should be, kind of like gradient descent except you generate random gradients and hope they're good... On the other hand, your parameters might already be close to where they should be but not quite there, and the right amount of noise would nudge them closer to there (if they should be increased, note there's a 50% chance of the noise value being positive, so pretty good), while setting it to any random value has a very low probability of getting it closer to where it should be if it already is close. That's just my reasoning though and I might be missing something, also reality sometimes doesnt like reasoning and instead prefers random bs like it does with the lion optimizer (which is better than adam, previous SOTA, but only uses the sign of the gradient to update, which is nuts)

Yeah, you're right. For some reason, I forgot to do it.

But that won't work if the length of the snake is 1.

​@Kofybrek to me that makes sense though, because the snake can't flip 180, cause the body is in the way. But if there's no body, it has freedom to move. Also if you attempted a 180 you would die... I don't remember if that's what my final product did. I'll have to check. Love your videos! I just found you and you have a new sub.

nice cometari

Lol exactly!

Yes.

No, I haven't. Sounds interesting though.

I think evolution strategies would be much easier to implement

I didn't use any others. And I don't think using them is gonna change something.

@@Kofybrek I mean there is usually a huge difference between a simple linear projection and an actual neural network. Add something simple like ReLU or remove the hidden layers because they don't actually do anything in this case.

it's short for "input".

@@Kofybrek thank you, very useful prefix btw

It just looks better to me.

AI is not language deoendent. Its pure maths

@@Ezdiess alright then where did he learn those maths

@@Eren_Yeager_is_the_GOAT my journey began with some genetic algorithms on RU-vid. Then I followed backprop tutorials online. Then learned about momentum and reinforcement learning I suggest starting with evolution strategies, it's super simple like genetic algorithm, yet can be more powerful than backpropagation

@@revimfadli4666 thanks 😊

yeah exactly!

Damn, you're right! I didn't think about it that way.

On the internet mostly.

I believe its call "Yoda notation" it is useful to avoid some kind of unintended compilations which can result to bugs insanely hard to find if I remember correctly

exactly!

Yeah, I'm weird.

You can use the Minimax algorithm to achieve it. It's very easy to do.

@@Kofybrek Your videos are great. I like those very much. Most of the content creators are commercial instead of being aesthetic. Hope you do greater in the future.

It's a joke, and "rand()" is less accurate than the random library.

@@themightycxzeriallord Ohh... i mean you a right and i would love to keep my ribs pls.. xD

I would've preferred C, but not everyone is ready for that. However, Python would be the worst choice.

@@anon_y_mousse python is actually the best choice when it comes to data sience and ai
