Creating the PERFECT Connect 4 A.I. 

Poor Isaac just wanted to eat his apple :(

Should be called “bullying nerds by being a bigger better nerd”

"Alpha beta pruning is like normal minimax, but a bit fucky-wucky" Thanks Code Bullet, I needed that for my CS exam tomorrow.

I am truly impressed by how energetic cb has gotten, he used to be so calm and composed all the time XD

3:34 To be fair, placing down 8 pieces in one move is a pretty solid option for the cpu to make

Online board game: * exists * Code Bullet: "And I took that personally"

i like how his whole thing is "bullying nerds" now but he's making a fucking connect 4 a.i.

I ran a Connect 4 AI competition in college, not realizing it was a solved game. The winner just made http calls to an online minimax game to get their next move...

Something isn't right. He's posted within a month.

I'm convinced code bullet keeps making AI's because he finally wants to win games he used to lose at when he was a kid.

Evan: "C++ good, python bad" Me who is currently learning C++ in school: *signature look of superiority*

I love how the board he used as an example is an impossible state 2:56

I like how he says “time to plagiarize” but then he literally gives pascal all the credit.

He's posting more than once every 3 months you know this man really had nothing to do

In case if anyone doesn’t understand: A chair is a type of seat, typically designed for one person and consisting of one or more legs, a flat or slightly angled seat and a back-rest. They may be made of wood, metal, or synthetic materials, and may be padded or upholstered in various colors and fabrics. Chairs vary in design. An armchair has armrests fixed to the seat; a recliner is upholstered and features a mechanism that lowers the chair's back and raises into place a footrest; a rocking chair has legs fixed to two long curved slats; and a wheelchair has wheels fixed to an axis under the seat. Chairs can be made from wood, metal, or other strong materials, like stone or acrylic. In some cases, multiple materials are used to construct a chair; for example, the legs and frame may be made from metal and the seat and back may be made from plastic. Chairs may have hard surfaces of wood, metal, plastic, or other materials, or some or all of these hard surfaces may be covered with upholstery or padding. The design may be made of porous materials, or be drilled with holes for decoration; a low back or gaps can provide ventilation. The back may extend above the height of the occupant's head, which can optionally contain a headrest. Chairs can also be made from more creative materials, such as recycled materials like cutlery and wooden play bricks, pencils, plumbing tubes, rope, corrugated cardboard, and PVC pipe. In rare cases, chairs are made out of unusual materials, especially as a form of art or experimentation. Raimonds Cirulis, a Latvian interior designer, created a volcanic hanging chair that is handmade out of volcanic rock.Peter Brenner, a Dutch-born German designer, has created a chair made from lollipop sugar - 60 pounds (27 kg) of confectioners' sugar. Ergonomic design distributes the weight of the occupant to various parts of the body. This is done by having an easily adjustable seat height. A seat that is higher results in dangling feet and increased pressure on the underside of the knees ("popliteal fold"). It may also result in no weight on the feet which means more weight elsewhere. A lower seat may shift too much weight to the "seat bones" ("ischial tuberosities"). Gas springs are attached to the body of the chair in order to give height adjustment and more comfort to the user. Some chairs have foot rests. Around 15% of women and 2% of men need foot rests, even at the 16-inch (41 cm) chair height. A stool or other simple chair may have a simple straight or curved bar near the bottom for the sitter to place their feet on. Actual chair dimensions are determined by measurements of the human body or anthropometric measurements. The two most relevant anthropometric measurement for chair design is the popliteal height and buttock popliteal length. For someone seated, the popliteal height is the distance from the underside of the foot to the underside of the thigh at the knees. It is sometimes called the "stool height". The term "sitting height" is reserved for the height to the top of the head when seated. For American men, the median popliteal height is 16.3 inches (41 cm) and for American women it is 15.0 inches (38 cm).The popliteal height, after adjusting for heels, clothing and other issues, is used to determine the height of the chair seat. Mass-produced chairs are typically 17 inches (43 cm) high.Researchers such as Mary Blade and Galen Cranz found that sitting on the edge of a high stool with feet on the floor is less harmful for the lower back than sitting up straight on a conventional chair.

“…which is like normal minimaxing but a bit _fucky-wucky”_ is an absolutely gold line

Code bullet: *uploads within a month* Me: don't do that, don't give me hope...

Honestly, that was such a smart ‘cheat’. I’m impressed.

I feel like code bullet is going to be the guy solely responsible for the robot uprising

Codebullet as a youtuber is much like his AI. He evolves gradually and is becoming not just competent but very good and funny. Then all of a sudden does something weird like stop uploading for at least a year. But in the end his AI’s always work so he’ll be back.

“That’s where this week’s sponsor comes in” Me: more like this month’s sponsor

I remember back in elementary school during snack time a whole group of people were playing connect 4 super competitively lmao

I like how code bullet curses alot, steals programs, and is very non kid appropriate, and then got sponsored for a company that teaches kids to program

This channel is literally perfect I don’t know how you’ve done it, but the content just ticks every single box, boxes I didn’t even know existed

subbing to this guy is a constant cycle of: 1. forgetting he exists, 2. Immediately becoming grateful when he uploads, 3. Binge watch all his vids 4. repeat

This is essentially how chess AI is made. They build a table base for openings, then brute force via mini max after the table runs out. Then, since chess is so open to repetition in the endgame, i think a lot of AIs also have table base endings programmed in as well.

I’ll never not absolutely love bullets attitude and banter while making his videos. Absolutely amazing and it’s so much fun to watch. Love this channel

8:00 “I was this close to giving up” Hands are shoulder width apart

Damn he uploaded in less than 2 months. The Code Bullet AI is evolving

CB: “minimax” Me: “i’m listening” CB: “In Python” Me: “oh no”

I want to point out that Evan has changed his language of choice from Javascript to Python. That's character development.

The fact that he uses MS Paint for his board animation istead of the actual game he coded himself just shows his confidence in his code.

I love how as the channel grows, as CB gets more comfortable with his "persona" in his videos, the greater the memeage that seeps into the videos. And at the same time so does the refinement of the actual content (the actual coding/programing) in the video. They increase in equal parts shitpost and genuine content quality. Don't you ever change CB.

There was a Connect 4 game released in the 90s that was a PVP online game, in the game there was a feature "Next Best Possible Move", which would tell you the best place to put your next counter. Unless your opponent also knew of this feature (most didn't) then you were guaranteed to win, and it was pretty much instant when you called it. Unfortunately it's been so long since I play it, I don't remember it's name. However websites that do that same thing have existed just as long, and are just as fast.

I think the “seeing 12 moves into the future” thing is still really good.

Alpha-beta pruning: "Just like regular minimax but a bit fucky-wucky" Actually dying at how accurate it is, haha

that intro, judging by the comments, is SEVERELY underrated

This man could literally make a video about anything and I would watch it cause of how entertaining he makes these videos. Amazing Job with these videos

I genuinely believe Code Bullet would make a fantastic teacher one day.

"son, what did you do today" "well i watched an aggressive australian man hack an online children's game for his own amusement. and oh yeah he profusely swore the whole time"

Code bullet: uploads more than once a year Everyone: somethings wrong I can feel it

“So, mathematically speaking… I’m ғᴜᴄᴋᴇᴅ.“ - Code Bullet

Honestly the boost you added is completely valid. Many algorithms, especially chess ones have the first couple moves in a dictionary for the same reason of optimization and speed, and later games having less possible options

Ah, a sponsor. That explains all the swearing and disobeying mama Susan.

Impossible events: Pigs flying Raining cats and dogs Code Bullet uploading a video without curse words

Remember, in coding, copying from others isnt cheating it's learning, imagine if doctors just had to wing it during surgery

that was such a wholesome sponsor i low-key wish i had an excuse to use your code

Codebullet: next video will be more ambitious Everyone: see ya in 2021

Code bullet: swears in his videos Also him: gets sponsored by a company that makes products for little children

I love the post-video rambling that he refuses to cut. Really brings the whole thing home

I wish there were more videos like this. Funny, entertaining person doing something cool in a random, interesting field.

Can we get some love for the mastermind Pascal, who without, this video would not be possible. Thanks Pascal, you beautiful creature.

It’s 2:16 am. Code bullet is more important. I always love seeing all your videos. Keep up the amazing work!

I'm laying here sick in bed with the stomach flu and this feels like a fever dream.

I love videos like this because I enjoy watching the pure ingenuity of developers when they get stuck on something.

CodeBullet: “and that is where this weeks sponsor comes in.” Everyone: *more like this months sponsor if we’re lucky*

What if CB made the PERFECT A.I. to fix his upload schedule

Bro dropped the hardest connect 4 edit and thought we wouldn’t notice

Never having watched this channel, I actually thought this was about to be a very formal and technical explanation of AI and coding. I was very wrong. However, I laughed my absolute ass off, so well done 😂 I subscribed.

Every game ever: Code Bullet: So I made a AI that can destroy humans...

Within a month, he post new videos with good quality animations. Me: "Impossible."

He really did a great job on this one, nice one man. I really enjoyed it plz keep the good content coming.

The chaotic energy of Code Bullet is what gives me life.

3:46 "Guess who knows a lot about optimization" Probably not the guy working in Python. I could be wrong, though

CB: *Curses within the 30 second mark* Also CB: *Gets a sponsor* Me: How

OH THIS IS AWESOME THAT OPENING WAS AMAZING

this beautiful editing gives my life meaning

“Am I cheating? Maybe...” Wasn’t that the goal?😂

The bot's profile says 261 wins, 26 defeats for Connect 4. That's a 91% winrate. It also says 0 wins, 2 defeats for... Battleship?!

THE EDITING JUST KEEPS GETTING BETTER OH MY GOSH

The AI isn't perfect. It doesn't eject all of the discs if it's about to lose.

"Like normal minimax, but a bit fucky wucky." - Code Bullet

When his art skills are improving more than his coding skills....

C++ is perfect for this simply because of template metaprogramming, most of the calculation can be done at compile time, especially for something like this where there is a limited number of states for the board to be in.

Ok I REALLY love that this ai you made, sets up the EXACT trap I would use against my friend. It was always a fight to calculate moves 5 steps ahead with her, so we would both have to resort to creating a double trap where no matter what, it would force the player into placing a piece that would allow the other person to win, or a situation where if they tried to block one winning move, another winning move opens up frequently we would get into a cat and mouse situation where we're blocking each other's moves to the point we've almost filled the entire board. I think we've ended in draws before too I'd love to play against this AI in connect 4

Code Bullet is getting even more cynical and sarcastic. I think I like it. Edit: By the way, I like the ramble at the end. Do that more. 👌

"If you clicked option A or B then you don't know me very well." Evan, you literally went from JavaScript to Python for your Deep Q Learning car video...

I have no idea where this guy went, but I really hope he comes back when we need him most.

it's an honor to see u grow from destroying games to destroying games + hardcore memes

Wait, Code Bullet has a website, where his origin story tells how he hates Python and despises it’s simplicity. So, I guess you could say: You were supposed to stop the Python Programmers, not join them. Bring balance to programming.

Nerds have to be bullied, and since this year most were able to avoid school, I'm happy the australian code man came to deliver justice

The last 2 minutes of this video are the best!

This one was so perfect and fun i hope you keep it going,💜💜

“I’m not good at optimization, or programming, or Connect 4” Your name is Code Bullet.

"So mathematically speaking, I'm f*cked." Good lord have I been there

This is exactly how I programmed my chess computer, but used Crafty as a base and just added onto that. I was only 14 at the time so gimme a break. So cool to see you create the base!!

how am i only now learning that this channel exists? :O you rock dude.

Would you rather: Win the lottery or Code Bullet having a consistent upload schedule Just kidding, neither one will happen

3:33: "Alright, I'm gonna need you to consider every possible move you can-" _dumps all of his yellow pieces in_ "No, you don't get to _take_ every move, you-" _dumps more yellow pieces in_ "Why are you dropping extra in the first column?"

this was the most enjoyable vid ive seen on this channel

CodeBullet is the type of guy to make a whole game with quick adaptable enemies and call it it a small project

"If you picked C, that's a little insulting" Well, I mean... You DID ask, CB. Did you want us to lie to you?

"Plague left the game." CODE BULLET HAS SAVED US ALL.

Dude this is the most hilarious editing of all your videos. The TV remote attached to a gun was so funny.

9:23 CB: Non non non Me, a baguette speaker: OUI OUI OUI

Code bullet: It’s not really cheating Aalso code bullet 5 seconds later: so I’ve optimized this cheat so hard I have multiple divorce lawsuits and I aint married

Anyone: Makes one move. CB: And that's where you lost.

I can’t explain why I like these videos so much. I barely even understand coding lingo

I like how I don’t know what he is saying but I love he’s content

Codebullet: Knows he'll have to calculate millions of moves and needs heavy optimization as well as multithreading. Also Codebullet: Starts coding in Python
