New favorite insult: "You're about as good as randomly pressing the left key"

Tommy looks five moves into the future.. he sees his failures coming and has no choice but to helplessly walk towards them

Hearing you switch between calling the ai tommy and tomas when you’re frustrated is like a parent being upset at their child

When I was a kid I didn't even know there was a strategy and thought it was a clicker game where you just swipe as fast as you can randomly.

"it keeps lower scoring tiles away from the highest score tiles" So the AI enforces aristocracy.

Code bullet is so brutal that he doesn't creates algorithm for game, He creates game for algorithm

Being named Thomas, I felt quite called out through this

“Every one has the right to an opinion but not everyone’s opinion is right” Best quote of the decade

Plot twist: It was his friend actually named Thomas playing all along

I like how even when "Thomas" finally succeeds, it's still less efficient than any even slightly smart human player, making Tommy sort of pointless, but he always was a problem child and it's the journey that matters, not the destination

"Thomas kinda sucks" I hear enough of this normally, I don't need it to happen here too

Wow. I was just impressed with you recreating the game..

Tomas: "I've looked 5 Moves in the future" Code Bullet: "In what one do we get to 2048?" Tomas: "One"

"I CAN GO TO BED" has to be the funniest/saddest thing I have ever heard

As somebody who is named Thomas, this ai is basically a perfect recreation of anybody named Thomas. They fail at everything for a while, then somehow get it out of sheer luck.

Ai learns to code Ai

"failure is important for learning" so that's why my dad says I'm important

I love how much "failure" you actually include in your videos. It's interesting to watch how many types of things can actually go wrong while programming, and hearing what your thought process is to overcome them.

Plot twist: hell release the second enigma machine video in the year 2048..he's leaving us clues

Sorry I wasn’t performing well

AI learns to take over the world -Code Bullet Video 2019

Your second approach reminds me of the Othello algorithm I wrote for my introductory coding course a few semesters ago and I just wanted to say, I 100% understand watching said algorithm come *so close*

I some how keep arriving at your videos late at night when I am searching for vids to watch and I always get so fascinated by you content.

I felt so sad for him when he said “The next improvement was at generation 227” that’s gotta be so depressing

That moment at 9:08 where Tommy could have just gone up left left and reached 2048

coding is just "if" statements - a wise man 2021

I finally beat this game after so many years, I can die happy now

Code Bullet: “Alright, I think I’ll go to bed.” Thomas: “You’ll go to bed when we’ve reached 2048.”

3:40. Well, that’s literally the strategy I’ve gone with for the past 2 years...

Seeing you use processing is so nostalgic. Processing is fantastic

Hey! I actually made a 2048 ai in college. Takes me back. Mine performed okay, but the algorithm was definitely trash compared to the top tier algorithms. Was satisfying to see it all work though.

"what's up guys, today's video is in 2048" -code bullet accidentally reveals his origins

When I went down the rabbit hole with this game, my strategy revolved around one simple restiction: choose a direction (in my case, up) and never move in that direction. A consequence of this is that the largest tiles end up on one face, similar to your "top left for highest value block" strategy. I wonder how the AI would do with this restriction in direction. Edit: 2048 became an easy target, if I recall correctly, 8192 was the max I reached before throwing the game in my "NEVER TOUCH AGAIN" category.

I love how many voice cracks he has, it makes him seem so much more human and relatable then these other youtubers with over 1 mil subs

Bullet here explains the definition of camping “TOMMY KEEP TOP LEFT”

You should've told it that in addition to having the highest possible number in the top left corner is good, it should also prefer having as much free slots as possible and get rid of small tiles as much as possible

My highest tile is 8192. Take that thomas.

You’re teaching me better than my professors did

Seems like using NEAT to evolve an evaluation metric for the lookahead approach would be a useful fusion of the two methods.

"Yes, I can go to bed!" the typical software engineer saying after a project XD

The first generation is already better than me.

4 years later and i am still waiting for that enigma video.... you cant leave me hanging like this :(

Perhaps a better scoring algorithm would reward keeping tiles of the same value adjacent, and also somewhat reward keeping tiles of almost-the-same values adjacent. Also reward empty space, because that's your distance from the loss condition.

CB: Since the difference between random movements and intelligent movements is very small... Me: Yes! I'm almost intelligent! edit: 1.5k likes :O

"Everyone has a right to an opinion, but not every opinion is right" I love it, I'm stealing it for future arguments!

i guess, it can take maximum after some "little" time period) (maximum is when all board is filled by the "snake" from 131072 to 4, i`ve did it by myself, and much people too) looking forward to see video with maximum)

Crazy how much calmer and happier he sounded in his old videos

For those curious like me of the BGM in 8:18, its; "25-03: There Is Nothing Left to Say or Do (Short Version)"

that moment when the segway was so good you didn't even realize it was an ad

Every single AI video: It’s evolving, just backwards

If there was no visuals this would be the title: Man screams at someone (presumably his son) for 11 minutes and 10 seconds

oh god.. 8:22 feels like when you’re on the last mission of a game and a slowed down instrumental version of the main theme plays…

ive never watched your channel on my pc and yet I've been recommended you, I don't mind

I have no clue what youre saying half the time but your channel is amazing

*Make an AI learn to play Windows XP Pinball??* *I WOULD LOVE IT if it makes fancy combos continuously or see what he prefers to do lol*

You are my favorite UKposts channel man. Love this shit

I think the issue with using a MinMax strategy, that is the game states algorithm CB was waltzing around, is that it cannot accurately account for the randomness of the new tiles that spawn in. These new tiles have a random location with a probabilistic value. When 'aiming' for a future state, it is possible that state is unachievable because the tiles needed to get there didn't spawn in the same locations with the same values.

CB: keep the highest tile in the top left Tommy: how about... no?

1:36 “let’s see what happens when we press the up arrow - aaaand they’re gone” 😂😂😂

The video I been looking for for a WHILE

I still want that second enigma video... Or, to be fair, any video.. Just keep making videos please.

It's April 21 2019 still no part 2 of enigma machine

**Instant click**

It sounds like you implied you were using the minmax algorithm to evaluate the future game states. When evaluating the game state, you could take into consideration the possible locations for the new tile & its value (called substates) and apply a modified minmax algorithm to those substates. I can tell that this is not being done because of the move at 8:25, where 256,128,128 is moved right. The minimum state for that move would have been a 2 being added at the top left corner, permanently (for the forseeable 5 future moves, actually) displacing 512 from being in the top left corner. A left direction in this instance would be the better move. I'm halfway motivated to make a better algorithm for this game myself now

While keeping the biggest number in the corner and the next biggest right next to it is an important part of the winning strategy, it's also worth noting that the undo function is quite useful for any unlucky spawns. For example, if you are forced to move the biggest number out of the corner and a 2 spawns in the corner, you can undo the move3 and do it again in the hopes of a better spawn. Or another one could be a 2 spawning when a 4 would be better (or vice versa). Or times when the spawn happens on the wrong line and it would mess up all your plans. While a lot of these examples usually won't prevent you from getting to 2048, getting into higher numbers requires knowing when to use the undo function (also worth noting that you can only undo 1 move at a time).

He will single handedly create an AI that will destroy the world.

AI learns to play threes. Threes is a much more interesting game that was released before 2048. It takes a lot more strategy and just looks better

In evaluating states, it is not just highest number to the corner that should matter, but a more general "orderliness". Fewer tiles is better than more tiles and tile's nearest neighbors being numerically closet i.e. 2's in line with 2's or 4's is fine, 8's less so, etc. I would love to see you try this strategy, but I see this video is 5 years old!

The second example used for game states (5:22) is a very thoughtful game state to be in since there are only 2 moves to get out of the situation

Thomas: Is an AI and within 5 tries reaches 2048 Me: can’t even get to 512

7:50 - 7:52 That made me laugh harder than it should

I think it would be a good idea to add an additional option like if the box with the highest score is on the left corner and that row is not full of 4 boxes then never go right. Also, if that works I think this thinking should apply also for the second row with an exception when it will make an addition from second to first row.

I remember figuring this out and maxing out the game because you couldn't fit any more unique tiles on the screen to add together

I clicked the subscribe button twice. I was already subscribed tho

1:19 "They do a quick fusion dance..." Instantly subbed

This just popped up, I’m expecting a video in the next two weeks. UKposts always does this to me for some reason: a video I’ve already watched is re-recommended to me, and less than a week later a new video comes out. Hope I’m right

Me: *goes to yt to find some info and help on sth* YT: i’m gonna put a super interesting video from CB om your frontpage to distract you for a solid 11 minutes and 10 seconds

Enigma!!! Gimme me Enigma!

"my man thomas looks 5 moves into the future" This is King Crimsons ability

i think the issue may have been in not letting the highest tile move also using tile stacks to favourably rearrange the board also moving large tiles to make spaces causing a tile to spawn that couldnt be merged...

Antennas are perfectly recreating facial expression, it's awesome

I found your channel from the enigma video, would be great to see some more!

_Ai learns how to take control of humanity_

Okay, that subtle fusion dance make me so happy inside

I like to put the biggest tiles in bottom right and work from bottom left to right but this works too

me: *hears over-dramatic royalty-free music* also me: yeah dis the one

This was even more hilarious to me because my real name is Thomas but I rarely go by that anymore.

Congratulations on 6.9 mill views mate! Nice

YOU PROMISED US!

fusion is just a cheap trick to make weak tiles stronger. *im kinda upset no one has made this*

I just realized Doing a circle with the arrow keys is op

when he said try not to subscribe too hard when making some squares on a screen I actually subbed.

At 9:07 your A.I. was within 5 moves of victory and it made the wrong move. Luckily he got there still anyway a few seconds later

Watching this i thought "I thought the Ai was supposed to play the smartest move" Thomas proved me wrong.

I have a feeling the NN could work better if it was rewarded for the amount of turns the highest tile was in a corner as well as minimizing the amount of tiles on the board as opposed to a blanket, get the highest tile you can approach. Then again I am an economist not a programmer. Great work man

I think it should be rewarded more for merging tiles. I could see a few times where it preferred to leave identical tiles next to each other rather than merging them and that made the tiles fill up and lose the game
