Re: ChaosTrains

I do notice that many (or maybe even most) of the trains which get started in ChaosTrains will continue in B3/S024568, and you can usually switch back and forth between those two rules without derailing the train. In many cases, you can also switch between ChaosTrain and the less explosive B3/S02456...

Re: MCell Weighted Life (Patterns and Rules)

Hector, I like that gun - it is quite similar to the simple guns found by Emmanuel Sapin. The other patterns are nice too - I hadn't appreciated Midges until your post. I thought that if you like Midges, you might be curious about Midges-DN, one of the MCell Weighted Life rules left out of the origi...

Re: ChaosTrains

So, ChaosTrains is B36/S2ei3aejky4aijkqtwyz5aijkqrvy6aeik7e MCell Weighted Life rules PuttPutt and Ben's-Rule-9 also explode along one axis. I was hoping maybe comparing their rules would be instructive. In Alan Hensel's notation ChaosTrains is B36/ S2ei3aejky4aijkqtwyz5aijkqrvy6aeik7e PuttPutt is B...

Re: Non-totalistic Rules - notations, projects, & discussion

I like your degree attribute, and your alternative table of the 51 isotropic configurations -- makes sense! But I didn't understand your last paragraph --which rulespace are you referring to? And how did you arrive at your list of promising B/S rules?

Re: ChaosTrains

Ha! You keep posting better and better rules that "explode along one axis" -- this one is great! Each time you post one of these rules, I think to myself that I really ought to organize my patterns in the B3/S2456 family of rules. I may never get them organized, so I'll just mention this: If you did...

Re: Non-totalistic Rules - notations, projects, & discussion

Emmanuel Sapin's research is amazing. It should be of great interest to anyone who reads this forum. I've known of Emmanuel's work for quite some time, but I foolishly neglected his work because I didn't understand his rule notation. You guessed it - he uses Alan Hensel's non-totalistic notation!

Re: MCell Weighted Life (Patterns and Rules)

One of my favorite rules in the collection is Simple Inverse Fire, by Ben Schaeffer. As with HexInverseFire, the best introduction to the rule is to fill in a large block and watch what happens. In Alan Hensel's notation, it is B2eicv4568/s156ak78 In Weighted Life notation, it is more cumbersome: NW...

Re: MCell Weighted Life (Patterns and Rules)

Hi Hektor, Here's how Weighted Life works: For each cell, let alive = 1 and let dead = 0. Let there be eight weights surrounding the central cell. (Northwest_weight, North_weight, Northeast_weight, East_weight, etc). Now calculate a temporary number (call it "n") like this: n = Northwest_weight * (t...

Hi Paul! Yes, I find that SimpleInverseFire output very interesting, particularly the diagonal ship! What is even more interesting to me is that you seem to found ships I didn't, but I seem to have found ships that you didn't as well.

Non-totalistic Rules - notations, projects, & discussion

This thread is for the general discussion of non-totalistic rules. Life is called a "totalistic" rule or an "outer totalistic" rule because the cells surrounding the center cells are totaled, and these totals determine what happens next. There are also completely totalistic rules in which the center...

Re: Non-totalistic Rules and Weighted Life (Scripts)

This script converts Weighted Life rules into Alan Hensel's non-totalistic notation.

It also may eventually be helpful when using Paul Too...
