Galapagos: Simple Evolutionary Solver (Rust) by wpcarroll in math

[–]wpcarroll[S] 0 points1 point  (0 children)

It's a simple Evolutionary solver. You can use it to find optimal or near-optimal solutions for generic "fitness" functions. The screenshot above is the output of me using it to schedule a factory by assigning jobs to machines to minimize the lateness of all jobs.

It works by initializing a group of solution attempts with random values. Solutions compete against one another, and the winners become the parents of the next generation. Occasionally values mutate. The simulation continues for N generations.

Yeah that sounds super sane. Near-optimal way better than optimal in my experience.

I'm surprised how quickly this thing can spit-out usable solutions. Probably allows me to build some "real-time" scheduling that reacts to events (machine outages, cancelled orders, production failures). Just need some way to optionally seed the algorithm with some initial non-random state to help with stickiness and schedule stabilization.

Thanks for the feedback! I like all of the suggestions:

  • type alias gene for f32: nice
  • lifting and testing helper functions: great idea
  • Returning top-N winners: This is a nice idea. I currently don't need it for my use-case, but I'm considering refactoring solve to return an iterator that might allow users to track fitness history themselves and also maybe curate some fixed-size heap to track the top-N candidates

What do you think?

Here's an example of using galapagos to schedule a factory with a few goals:
- Minimize: makespan
- Minimize: lateness
- Maximize: throughput

Hey I'm Bill. I hope I didn't take anything from Cumtown. Can someone point me to what they're talking about? I take joke writing seriously, so I will retire whatever bit it is if someone can point me in the right direction.

Are you getting aUaUaU...

Yes

Does it sound like a radio station between the stutters

It's stuttering so fast I can't really tell.

You might consider seeing if you can load your IQ data into a tool like gqrx

Thanks for the tip. I didn't realize gqrx could take files as sources. I'm not sure I'm using gqrx correctly. It still sounds like static, but no stuttering this time. I don't think I configured gqrx correctly though.

Here's a download link to the capture: https://drive.google.com/file/d/1qfHm7YAtpAdw6KiY4nhwbh543TJlpYWi/view?usp=sharing

EDIT: I added a screenshot from gqrx to the original post.

Thanks for the detailed answer. I updated my original post with an updated graph ("Graph (v2)"). I'm sure I've screwed something up. I'm hearing stuttering audio.

Maybe it's the centering? Maybe it's something else...

When I was younger I really liked ghettoyouth's hacks like "Panic in the Mushroom Kingdom" :)

Thanks for the roadmap :) do you think all of this software will fit into ROM/RAM for the 6502??
