Back in 2015, I made a rule set I called "Attract and Repel" and posted it in this thread: https://conwaylife.com/forums/viewtopic.php?f=11&t=1751 . The concept was to create a set of rules that would appear as if cells were pushing or pulling each other along. It ended up being much more interestin...

Here is a cellular automaton that creates wave-like patterns using relatively simple rules, the Java code can be found here: https://gist.github.com/SeanBP/1c1baadcf064467629d9 . The idea is that each cell contains eight vectors (each pointing to a different neighbor) with a given value. That value ...

I think these kind of rules don't fit well with golly. When I make the rule with only 16 states, golly chokes pretty much with it. Hm, I'm developing a bad habit of making rules that don't fit in with Golly. I think this rule will be easier to explore in SquareCell, where I can make it have an arbi...

a new explosive rule This rule is definitely tot explosive because the total of all the cell values cannot increase: The clump would spread out until all cells are ones and stop expanding. I suppose "explosive" is the wrong word choice. I mean that the cell count will increase rapidly initially, bu...

There is a similar rule (Bak-Tang-Wiesenfeld sandpile model) on the Rule Table Repository: https://github.com/gollygang/ruletablerepository/wiki/TheRules This is similar, the main difference being that Sandpile spreads out in small increments at a time, while mine tries to get rid of all values at ...

I've come up with a new rule that is meant to take on some wave-like behaviors. The basic idea is that each cell with a positive integer will get split evenly into its adjacent neighbors in the next tick. If the value can not be divided evenly, the quotient would instead move into the neighbors, and...

I'm still curious to see the path one cell takes during a run, if anyone is still up for the task. Also, I'd like to see what would happen if we included attracting cells into the rule, although it will be more difficult to code how cells merge. The way I wrote it, all the repel cells that merged su...

"greyship"? x = 43, y = 44, rule = RepelTrig_D0 13$28.QD$26.QM$24.QM$22.QM4.QD$20.QM4.QM$18.QM4.QM$16.QM4.QM4.QD$14.Q M4.QM4.QM$13.P4.QM4.QM$13.F2.ID4.QM4.QK.B$16.H2.QCM3.QCGM2.F$14.B.GEG M4.IE$14.F6.H.GM2.QC.IBK$26.HM3.F$16.H2.D4.QM$21.H.M5.QJBC$25.H2.GNM.

A couple breeders with quadratic growth x = 165, y = 224, rule = RepelTrig_D0 7$57.2A$56.A3.A.A$56.A2.A$59.A$57.A$60.2A3$61.A4$75.2A$19.2A53.A3.A$ 18.A3.A51.A$18.A$75.2A$19.A$75.A$75.A$78.A4$87.2A$86.A3.A$86.A29.A2$ 56.A30.2A16.A5.A7.A$107.A2.2A2.A$87.A11.A2.A4.A$55.2A30.A10.A4.A.3A2. 2A2.A7.A$90.A3...

5. Can someone tell me what this is? x = 54, y = 60, rule = RepelTrig_D0 22.C2.C$21.G2.G2$20.B2.B$26.Q2.I$20.I2.B2.QK2.D8.HJ$20.GEGFEGNE.P6.HD 3.K$29.F11.F$18.B$18.B.Q6BJ.QJ9.B$17.O2FN6FMFNME.D2.HD2.F$3.I$.C2.E$G 15.Q16BJ$2.H12.GN16FMEJ$36.E2$4.QBQ27BC.PC$2.I.M.N27FE2.M$2.N$35.J$6.

Interesting, it seems like someone thought of a similar idea. The idea of fixed cells seems helpful, especially for constructing machines. Although, I'm unclear how the rule deals with cells getting pushed not directly onto one of the eight squares without splitting.

Can someone post the Repel rules with the bug fix? I'm afraid I'm too much of a novice to know how to add in the changes. Actually, could someone post a list of all versions of Repel, with a comment of what makes each of them unique? I will edit my first post to include them. So many different versi...

Very interesting, the common spaceships in the previous versions are impossible, and are replaced by similar ones moving diagonally. Also, I found a couple space-fillers. x = 88, y = 130, rule = RepelTrig_D0 2$3.2A$2.A3.2A$2.A2.A3.A$5.A$3.2A2.2A2.2A.A.A2.2A2.2A2.2A2.2A10.2A2. 2A2.2A2.2A2.2A10.2A2.2A...

@Blinker
That looks interesting, could you include it with the D0 rule? Applying the D0 rule to any of the Repel rules allows for very complex machines aside from puffers.

Thanks, this rule is getting more confusing than what I can keep up with. Thinking it over, my "simplifier" algorithm is probably more complicated than looking at this from a purely mathematical standpoint. I'll start working on a rule where the direction is determined by trigonometry. We can call t...

Oh, I didn't notice that! Thanks for pointing that out, I'll change it as soon as possible, which might be a while, because of college.

OK, very sorry for the mass confusion I've caused. I found that squarecell and golly handled that pattern differently, so I tried doing it by hand, and I messed up. It looks like you all have it figured out now, so good job. I'm getting confused by my own rule...

It would be interesting to see the path one cell takes in this automaton. I'm sure it would make some very interesting patterns, especially when it splits. College is starting for me in a few days, so I can't try to code it myself. If anyone else wants to try to do it, I would be interested to see t...

Hello! Went on a vacation for a couple of weeks, I'm catching up. This newer repel rule is interesting, but it would probably be more interesting if we added the D0 rule to it as well. Otherwise, I don't think any complex patterns are possible. Also, bprentice found a discrepancy with how it should ...

I did find a breeder, but not one for the replicator. This is a MMM breeder that was made naturally. x = 140, y = 112, rule = Repel_D0 16.A2$12.2A3.A2.A$4.A7.A3.A14.2A$2.A7.A4.A14.A2.A$.A5.A.A2.A2.A$.A3.A 3.A3.A.A3.A5.A3.2A3.A$2.A.A5.A.A5.A4.A2.A.A2.A.A2.A$A3.A3.A3.A3.A4.A$ 5.A.A5.A.A6.A3.2A.A2.A$3....

I found a very large gun based off of those natural high-period oscillators. x = 64, y = 64, rule = Repel_D0 6$36.A4.A$34.A2.A.A$32.A4.A2.A$30.A2.A.A2.A.A$28.A4.A2.A.A4.A$26.A2.A .A2.A.A2.A.A$24.A4.A2.A.A2.A.A2.A$22.A2.A.A2.A.A2.A.A2.A.A$20.A4.A2.A .A2.A.A2.A.A4.A$18.A2.A.A2.A.A2.A.A2.A.A2.A.A$16.A4...

Just found five different rakes. x = 80, y = 50, rule = Repel_D0 39.2A2.2A$38.A2.2A2.A2$37.A.A4.A.A$40.A2.2A2.A$41.2A9$7.A.2A$6.A59.A$ 12.2A.2A$3.2A4.A2.A56.A$3.A2.A2.2A7.A50.A.A$.A4.A8.A2.2A47.A4.A$A2.A 2.A5.A2.2A53.A.A.A$A3.A.A2.A2.2A7.A47.A.A3.A$.A.A5.2A7.A2.A43.A3.A5.A .A$3.A11.A2.A45.A4.2A3.A3....

Thanks to bprentice, this rule has become a lot more accessible and user-friendly. Already, he has created several different guns and replicators. Here are the files to run the program: http://bprentice.webenet.net/Java%20Square%20Cell/ Just download the AttractRepel.zip file, extract it, and run th...

I found out a little more about the behavior of this automaton. A lot of the time, especially in smaller grids, it will decay fairly quickly. However, if the program creates a rake, it will last significantly longer. Because these rakes can rebuild themselves if they run into anything, they can run ...

That method looks daunting, to say the least. The trickiest part to put in Golly would be the "simplification" rules. For instance: . . O -----> . . . . R . -----> . R O Pushing the middle cell to the left. . . O -----> . . . Unless you assign a state to all 256 (I think) different combinations of n...
