24 alternatives to A TSP game I wanted for 10 years - built in 4 hours
For a decade, I’ve wanted to build a simple game that shows why the Traveling Salesman Problem is fun to work on. Something I could pull up at a party when someone asks “so what does your company actually do?” Something my kids could play and understand why dad stares at vehicle ro
A TSP game that lets players solve traveling salesman problems interactively. Built on the GraphHopper platform, it's designed for people interested in optimization puzzles and route-planning challenges.

This is the first iteration of a short game I’m making that tries to interactively explain some of my favorite math questions / ideas. My goal is mostly to get the player curious and not necessarily to explain absolutely everything. There were a lot of fun technical parts to building this: - For implementation reasons, it’s much easier if the lines all have integer intersection points with each other. To do this, when a new line is added I “cheat” by rounding intersections to integers and then splitting the old lines at the intersection into new linds (with potentially different slopes)…

Hey, maker here. After launching a daily word search game, I randomly thought of this math game while driving. Finally got around to making it and I think it turned out pretty cool. It’s a math search game that’s meant to help you practice your quick addition, subtraction, multiplication, and division skills. I’m hoping it’ll help people (even those like me who aren’t big on math) learn and increase their speeds. (There are also some settings you can enable to make the game harder) If you try it out, please let me know if you found it fun, if you have anything you’d like me to add, or if you…

Hi everyone! For several months now I've been stuck on the idea of a Minesweeper game that isn't just single player. This is what I came up with: • Live games allowing several people to play at the same time • Scoring system rewarding correct moves • Grid size, mines count, and players count set to make games as balanced as possible

Thought I would post in celebration of 1 year of my website being online. I've been working on it on and off and currently the website allows users to play Hex, Tumbleweed, Amazons, and Connect 6 against friends or against practice bots. I've been a long time player of some of these games and I felt for a long time that the world could use a few more popular abstract strategy games compared to Chess or Go. If you try it, let me know what you think. I'm always looking for new games or new features to add :)

I’ve been working on a puzzle game for a few years as a side project. The game is based on a small region of tiles in a grid that is mirrored, modified, and mirrored again. It’s based on a novel phenomenon I noticed where, once these mutations happen a few times, the original region can be hard to recognize. You have a feeling there are symmetries in the image, but they are just out of grasp. Going further, if only part of the region is visible, such as mirroring off the edge of the board, it adds to the feeling and it becomes a satisfying puzzle to solve. I originally published this on the…

Hi! I build an MCP server that allows clients to play Minesweeper. It turns out that Claude is not very good at it (makes obvious mistakes, hasn't won a single game on a 9x9 board after many attempts). I am curious how I can prompt Claude to do better?

OP here. Most Deep Learning approaches for TSP rely on pre-training with large-scale datasets. I wanted to see if a solver could learn "on the fly" for a specific instance without any priors from other problems. I built a solver using PPO that learns from scratch per instance. It achieved a 1.66% gap on TSPLIB d1291 in about 5.6 hours on a single A100. The Core Idea: My hypothesis was that while optimal solutions are mostly composed of 'minimum edges' (nearest neighbors), the actual difficulty comes from a small number of 'exception edges' outside of that local scope. Instead of…

Link: http://xoxo.cm The idea here was to build a multiplayer game with the lowest possible barrier to entry to get started. That is, no registration, no game setup, as few steps as possible to actually start playing. There's not much substance here right now and there's still a few bugs that need to be hammered out. I'm also thinking of expanding on the idea with some other simple games down the road. Any feedback or suggestions on the concept in general would be much appreciated.

Chess Twist▲29I continue my experiment of transposing classic games onto an irregular grid. I've previously released variants of minesweeper and checkers. And now I'd like to share my variant of Chess. Chess can be a pretty punishing game, but I thought this was nevertheless a way to make it even more challenging by making it trickier to anticipate your opponent, even though both players still have the same information. From the playtests I've done, that challenge is pretty compelling. It also seems to be more fun at 2 people, where both players keep surprising one another.

I haven't seen anything like this so I decided to build it in a weekend. How it works: You see a bunch of things pulled from Wikipedia displayed on cards. You ask yes or no questions to figure out which card is the secret article. The AI model has access to the image and wiki text and it's own knowledge to answer your question. Happy to have my credits burned for the day but I'll probably have to make this paid at some point so enjoy. I found it's not easy to get cheap+fast+good responses but the tech is getting there. Most of the prompts are running through Groq infra or hitting a cache…

Hello guys, I'm glad to present to you PlayAlgoShip, a web-based game where you solve fun algorithmic puzzles. The rules are simple, you need to find the correct algorithm that makes the ship collect all stars. If you succeed, you will unlock the next level! There are also live statistics like how many players are currently playing on your current level (you are not alone struggling!), the finish rate of the level, and how many players liked/disliked it. It's 100% free, I hope you will enjoy the experience!

Hello HN, last week, I stumbled over an old project of mine called Click The Number. I built it about six years ago to compare my clicking and reaction speed with that of my friends. The idea is simple – just click on the numbers in orders as fast as possible. I couldn't resist and rebuilt a lot of parts again, making them a bit nicer. I updated the design and added some features like a personal high score. It lets you keep track of your own best time (which makes it ever so _slightly_ more addictive). I'm curious what you think about it, and if you have any ideas where I could take it. Have…

This was a lot of fun to build! I have an autistic son who is extremely interested in power lines, electrical transmission towers, and how the grid works. I decided to build a little game for him. When I finally showed it to him with bated breath, he rolled his eyes and said, “Is it 3D? I’ll only like it if it’s 3D!” So, I decided to polish it up and release it to the world! You get a 9x9 map with one power plant, three houses, and terrain obstacles, and the goal is to connect the power plant to the houses with an optimal path. Beneath the coat of paint, it’s a graph theory optimization…
