I'm so excited for this to continue. It's the most clear and applicable explanation of this topic that I've seen so far!

Man, I love watching this guy teach. He makes things pretty easy to understand. Heck, even listening to this guy talk is entertaining.

I once made a project with a certain population of entities in a closed space, and they all had a random value for "beauty", on a scale of one to ten. As they wandered around and bumped into each other, they would decide if they wanted to mate. But each entity only said "Yes!" if the potential partner was their own beauty level or better. The child they had was given a value for beauty based on one of the parents for heredity.

Eventually, the entities grew old and died off. I also kept a running tally of the average beauty of the population over all.

After running the simulation for a while, the average beauty slowly went up until everybody was absolutely gorgeous. 10 / 10. And there wasn't even a single 9 left anywhere. It made me wonder why this hasn't happened in real life human populations. And then it occurred to me, "Oh yeah. Alcohol."

Great to see someone teaching coding with such passion, love your work!

This man deserves way more subscribers or needs to be the next elon musk or something

ishaan

He deserves more subscribers to be honest.

I learned so many things from his book and YouTube channel.

Finally, finally, finally, got the video to understand Genetic Algorithm in simple words✌️

deeppanchal

Amazing content, surely the clearest tutorial for genetic algorithms!

thibautevrard

Hard problems explained in a simple way. You are a pure genius. Your energy is contagious. Keep going...

Okay. On the first video I thought that this guy was crazy or something... But hey, if you sticked to the video, you saw that this guy has a very special way to communicate and teach.
Talking about Genetic Algortihm, his way of teaching it's very easy to comprehend and it's well explained. Congrats. Don't stop making videos and teaching with that awesome energy and thanks for the lessons !

Hope to see more videos like this in youtube.
Got here by Jabrils.

You are the 2nd best teacher ever. Your explanations are so clear and precise. I love learning from you, but not as much as from Hank and John Green.

"I love CS. This is just not a CS channel.
It's something else. I don't know what it is."
Lol I love him :3

Really this was so informative, and fluently and easily explained. The best part is getting examples and generating them on the go. This provides a really clear picture of the topic.

Amazing!! I'm am a mechanical engineer looking to use GA for optimization of heat exchangers and these videos helped me understand the basics of GA. Moreover listening to your lecture is fun. His non stereotypical way of teaching is fun!!

harshith

Amazing work, you made this algorithm sound so easy and understandable. Subbed. Keep up the good work! :)

i could not find a better explanation regarding this topic, THANK YOU <3

michealclarke

I'm in Bioinformatics, I just implemented an GA for metabolic data

BaderAlharbi

...this was the first video I watched while taking notes.

죄송합니다사칭하지않

Please do more of the theory part before coding, no hesitations. I play your theory videos and loop them, sleep. I always wake up as a genius.

chumaxonics

Such amazing content delivery makes me wanna cry. All the very best with your future endeavors sir.
