@MinglangDu – Hack Club Scrapbook

5:28am

created some extremely unoptimal code (exponential time complexity) for stockship. Takes around 10 minutes to run lol. definitely optimizing, or setting as a forbidden setting option buried deep in a menu if I can't optimize it

I have been doing this over the course of 2 days, but only now have I decided to post. I'm making a program that uses monte carlo simulations to find the best move in Battleship. UI attached below

didn't want to do much today but I realized that I hadn't released my minesweeper yet so i did that github.com/minglangdu/minesweeper/releases/tag/v1.0.0 btw i realized i accidentally leaked some audio in my videos. that's fixed now, and literally (0) no people saw it so ye

Practiced usaco today! It was mostly reading, but I was able to apply my knowledge to solve this problem

Today's usaco practice. This was definitely harder than I thought it would be, so it consumed most of my time. Learned quite a lot from the ~5 failed submissions and draft algorithms though.

I could only do one problem for USACO silver. I'll practice more for next time, as the problems were very difficult.

Made a buggy release in my AI project to begin implementing epochs. Github: github.com/minglangdu/AI-test No video this time since its too buggy to deserve one. BTW this is not committed, you shouldn't see it on Github.

Github: github.com/guywithnousername/wfctest I realized my algorithm wasn't updating the procedural generation after some time, so I spent some time documenting the code to understand it more. Hopefully this will help me find the problem. Here is the debugging (red means not filled in, and the all different possibilities for each square are in the brackets):
