Re: Algorithm for reversing the GoL rules

I've been working on implementing an approach to predecessor searching that AFAIK hasn't been tried before, and also I've trying to use this with deep learning to try and choose 'good' predecessors. My experiments were ultimately not as successful as I would've liked, resulting in modest, but not ...

Re: Thread for your miscellaneous posts and discussions


Why there aren't any Indian users? This might because:
Low education for most people
Low development for most area
3. the nazi goverment (the real reason cause 1&2)


I want to say that there are Indian people on this forum, for example me. (though I haven't been very active because I was ...

Re: Multi Period Photon Searcher

I have finally put up the latest version on github here: MPPS
There are quite a lot of changes in how you have to use it, hopefully making it much more convenient. More details should be in the readme file


It's somewhat annoying to have to compile a separate program, run it with the desired rule ...

Re: Spaceships in Life-like cellular automata


Excellent work! I was actually intending to suggest such a bulk search today, but you got to it before I could make the suggestion. I do believe there will be more to find with this method. It can also be used to identify nearby rules that have potential for such spaceships.

I've now searched ...

Re: Multi Period Photon Searcher

Here is version 0.2 of the program. There have been a lot of improvements over the previous version. The biggest ones are:

You can enable parallel evolution by using the optimal5 library and genrulecode.cpp to generate code. This greatly improves speed, but can't be used in bulk searches. You ...

Re: Spaceships in Life-like cellular automata

I have found some p2 and 4 photons that work in rules without any previously known ships

x = 30, y = 35, rule = B2456/S124678

Very cool!

Thanks!


By the way, I tried compiling with g++, but got the error

This seems to be caused by using the non-constant variable birth_survival in a constexpr function. It compiled after I removed ...

Multi Period Photon Searcher

Multi-period photon searcher is a search program which can be used to find photons with large (or small, but its less suited for them) periods. It can be set up to search for a specific period or it can be set up to search all periods less than a maximum period. Interestingly, the time taken to ...

Re: Spaceships in Life-like cellular automata



I found an interesting family of high period photons in B24/S27

Very cool! How did you find them? What program did you use? There aren't many programs that can handle high-period photons.


I found them using a c++ search program that I wrote. It is very similar to photonsrc by LaundryPizza03 ...

droid-logica: A 32-bit computer in Star Wars

Hello!
I have made a 32-bit computer processor in star wars. It uses a von Neumann architecture (which seems to be kinda rare among such computers from what I've seen) and is NOT an OISC. It uses self-modifying code for achieving jumps and loops. It also supports a practically infinite amount of RAM ...

Re: B2-ae3aceky4jkr5ijny6e/S1c2aci3-ir4cekrtwz5-aijr

This is a partial of a stable universal regulator which just needs a mechanism to delete signals which come 283-311 generations after an "enabled" signal

Thanks!
Although the regulator seems to break in some cases, it can be used as long as the enable spaceship is of the same phase as the clock ...
