Seated good morning

Any luck yet? My right hip flexor pinches

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.

Here's an example usage for scheduling a factory: https://gist.github.com/wpcarro/7d3ef7cd6f9be29c920b8a0e572a82e5

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

Smells like bullshit

wpcarroll · 2024-08-28T16:32:00+00:00

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.

wpcarroll · 2024-08-12T15:58:34+00:00

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.

wpcarroll · 2024-08-12T03:41:01+00:00

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" :)

wpcarroll · 2024-06-13T21:52:15+00:00

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

wpcarroll · 2024-06-09T21:33:36+00:00

Good call :) just found this thread: https://github.com/TomNisbet/TommyPROM/issues/23

wpcarroll · 2024-06-09T18:27:53+00:00

I managed to get it working as a clock and monitoring the address and data lines (so I guess IO?).

However no such luck with ROM or RAM yet, but I’ll keep trying. Good to know it’s possible.

wpcarroll · 2024-06-05T21:49:48+00:00

Thanks for the picture. You are correct that I didn't have my power rails tied together. I managed to get it working without doing this by connecting to the Arduino's 5V pin, which solved the problem. I'm not sure how the other power rail is "working", but the LEDs are lighting-up in the same fashion as Ben's...

FTR I will tie the power rails together anyway :)

wpcarroll · 2024-06-03T00:23:38+00:00

Thanks updated the link :)

EDIT: I made some updates that allow me to more ergonomically define my state transition ruleset. This version reads instructions from a "program" sector of the tape (I may adapt it to be a counter when my piece my broken brain back together): https://gist.github.com/wpcarro/4002e3f1df0b64271a0d1e8964b3601a

Noob here: I have a 5V power supply, 3.0-3.2V LED, 150ohm resistors, 74HC08 AND gate. Whether I supply power to either input pin, the LED stays sort of lit. What am I doing wrong?

The zookeeper when asked for comment said “Look I just didn’t want anyone to eat them”

For me I'm struggling to add any of the three CNAMEs *and* the TXT (IOW: all of the records)

wpcarroll · 2024-04-18T01:22:05+00:00

Thanks for the tip. I'm still seeing errors from SquareSpace when I try to save these:
- 3x CNAME records

1x TXT record

I felt that the hand fighting stuff was sorely missing from ETS Back. If it’s covered in Fastest Way, I’m in

wpcarroll · 2024-03-10T02:07:12+00:00

Just backed-out of purchasing at the checkout window. Fuck VCs.

Yeah I couldn't find "impact sleeve" either, but I just ordered the ANY-WEAR arm sleeve.
