Very nice! And so simple - I was evidently looking at this problem in a convoluted way.
The fastest I can make the (2,1) slope ship go is (4,2)c/52:
(2,1)c/(4n+2), p(8n+4), n>5:
x = 14, y = 20, rule = B2ce3cen4eknt5kn6-ce7c8/S01c2-ck4ciknr5aknq6k7e8

Indeed, all rational slopes are possible. It would be nice to know what the minimum period for any particular slope is, and to write a script to generate the ship of any given slope. It may be worthwhile finding the slide-reflect reaction with the lowest possible repeat time first.

As for non-integer slopes you would need a totally different kind of construction. I can't remember where the discussion about this topic was (fairly recently too) but any pattern which meets the traditional definition of a ship in a regular Moore neighbourhood CA has a rational speed, almost by definition of what is a ship. I liked the idea for creating a pattern which moved with non-rational speed, but it can't be periodic and therefore must grow in size over time. I suppose it might be possible to use these dot movers to do the kind of computation which was discussed, and the construction may not need to be a UC, but it's certainly going to be a lot more complicated than a small rectangle.

This is the fastest group of ships I could find in all known rules with slide mechanics:
x = 87, y = 38, rule = B2aei3-aijq4einrtyz5-ace6cei7e8/S01e2in3-ein4cejrz5eky78

The fastest direction of the ships seems to limit at 2c/11, which is much faster than the limit in the other rules.

The fastest direction of the ships seems to limit at 2c/11, which is much faster than the limit in the other rules.

Adding B3q allows some of these to go a bit quicker:
c/6 diagonal (p24), and (3,1)c/16 (p64)
x = 33, y = 35, rule = B2aei3-aij4einrtyz5-ace6cei7e8/S01e2in3-ein4cejrz5eky78

o2bo$19b2o$19bo6bo$b2o24bo$o2bo23bo4bo$26bo17$3bo6bo$11bo$11b2o$10bo!

The (2,1) slope ship can already go faster at (2,1)c/11 (p44) without B3q.

Personally, I prefer the ships made from bouncers with a smaller displacement - this won't result in the fastest ships but it does give the most flexibility in allowable displacements for the knightships, and I think will allow the lowest possible period for any given slope. I think these particular ships are also limited by the sparkiness of the reaction - it might be possible to tailor the search to reduce the extent of the spark somewhat.

Edit: Here's a bouncer which allows for lower period ships:
(n,1)c/(9n+1), p(18n+2), n>0
x = 73, y = 40, rule = B2ae3acnqy4aint5aj6c7e8/S01e2ce3cjnqr4acejknr5-jkqr6ik7e

Nice, that's got to be close to the limit.

Why are lower periods important, is it aesthetic or is there some use for it? Though I guess the same thing could be asked about speed.

Here's a reliable method to make (4n,4)c/(20n+4) ships for all n > 1:
x = 173, y = 100, rule = B2aei3-aij4einrtyz5-ace6cei7e8/S01e2in3-ein4cejrz5eky78

Take the base ship as the knightship on the far right, and to increase the slope by 1, simply evolve the bottom part 12 steps and move it down 12 cells, and you should get the next oblique ship in the sequence. It works for all integer slopes (seemingly). This is probably doable with a script.

The method works with diagonal (2,2) pushes as well:

Danny,

Your puffer and oscillator seem to be misplaced, they are not related to small adjustable spaceships.

Well, I guess it is, but the rule has adjustable spaceships and was posted earlier. I didn't want to point this out again in a different thread, so I chose here.

Wow! This is seriously impressive -- has anyone looked at the isotropic rulemin and rulemax to see whether there's a non-explosive rule supporting this family of ships?

Unfortunately, there doesn't seem to be a non-explosive rule in there. However, literally any rule with the same push reaction has this property, so if someone can find a rule with the push reaction that is non-explosive, we have adjustable-slope ships in a non-explosive rule.

This rule has the same reaction, but diagonal, and is non-explosive.

What do you mean by cover? Smaller adjustable-slope ships in area are available and more generalized speeds:
x = 45, y = 49, rule = B2ce3-knq4eqrwy5-ckq78/S012ck3cjnqy4cintz5acekq6in7c

This rule has a 2c/164, 4c/164 and 6c/164, which isn't something possible in previous rules as far as I am aware.

Are there any values of nc/x for where n isn't achievable at all?


Also, is this the minimum possible rule for these spaceships? Sadly it seems explosive.

All even displacements should be possible. The minimal rule is this:
B2ce3-knq4erwy5-ckq7c8/S012ck3jny4cintz5akq6in7c

Unfortunately it is still explosive. If you search with LLS for rules with the same bouncing reactions, you may be able to find a non-explosive rule.

This rule does not have the other bouncing reaction (where the ships bump each other up) if you were responding to the above by muzik. Regardless, that is the first orthogonal non-explosive rule that has the first bouncing reaction that I have seen, nice job.

This is a adjustable rule that allows for various speeds, as the 'reflector' can act colour preserving and changing:
x = 59, y = 134, rule = B2-ak3a4-cqrwz5iny6ck7e8/S01c2an3aeij4eiqz5jr6ak

A class that is similar to what we know anyway, but with some delaying options:

Re: Rules with small adjustable spaceships

Postby toroidalet » February 9th, 2019, 3:14 pm

A while ago I had an idea which would result in all rational speeds below a certain value (including unreduced speeds). Here is a proof of concept (except that there is only a push reaction; in such a ship the other side would pull the dot instead of push it):
x = 8, y = 35, rule = B2cek3-jkqr4kqrtwy5-cy6-kn/S02-kn3ir4ijknwyz5cin
o6$bo$obo22$7bo4$bo$obo!

Actually, it's a lot like a moving glider loop. To ensure that all speeds can be reached, the phase changes need to be a specific way (so that the ships with 1 signal inside have a period of 4n).

Perhaps a different ship without B2c should be used because then there only needs to be 1 column of space between the lanes.
[off-topic]
Coincidentally, the above rule has a second reflection reaction with this ship and a dot:
x = 5, y = 7, rule = B2cek3-jkqr4kqrtwy5-cy6-kn/S02-kn3ir4ijknwyz5cin
o5$3bo$2bobo!

It allows for really satisfying things like this:
x = 43, y = 35, rule = B2cek3-jkqr4kqrtwy5-cy6-kn/S02-kn3ir4ijknwyz5cin
20bo9$10bo3$13bo$12bobo$28bo2$o$15bo7$7bo4$21bo20bo6$33bo!

[/off-topic]
x = 4, y = 2, rule = B3/S23

I've been trying to find a reaction that can pull and flip in the same rule as a push and flip reaction, but no luck yet. I had actually tried to find a ship with this idea before, but I could not find anything.
Things to work on:
- Find a (7,1)c/8 ship in a Non-totalistic rule (someone please search the rules)
- Find a C/10 in JustFriends
- Find a C/10 in Day and Night

Here's another Generations ship which can be slowed by increasing the number of states:
x = 7, y = 5, rule = 235678/3456/7
2.3A$.5A$AF.CDCA$.5A$2.3A!


x = 7, y = 5, rule = 235678/3456/8
2.3A$.5A$AG.CDCA$.5A$2.3A!


x = 7, y = 5, rule = 235678/3456/9
2.3A$.5A$AH.CDCA$.5A$2.3A!


x = 7, y = 5, rule = 235678/3456/10
2.3A$.5A$AI.CDCA$.5A$2.3A!


...

x = 7, y = 5, rule = 235678/3456/100
2.3A$.5A$AsC.CDCA$.5A$2.3A!


With six states, the ship still sort of works, but behaves somewhat differently:
[code]x = 7, y = 5, rule = 235678/3456/6
2.3A$.5A$AE.CDCA$.5A$2.3A!
