R1 Weighted rules are in the range of R1 Moore rules.
You can represent them as MAP rulestrings

True, you're both correct.

Copy as MAP is only supported for 2-state RuleLoader rules.

I think it might be more interesting to have a conversion in the other direction. Sometimes, a MAP rulestring can be replaced by an equivalent rulestring that uses a range-1 weighted neighbourhood.

Converting from R1 weighted to MAP would lose weights (the specific weighted neighbourhood that was used). To convert in the other direction (when possible), one would need to choose (more or less arbitrarily) a specific weighted neighbourhood, and that choice would determine sets of survival/birth conditions listed in the rulestring. Some choices of a weighted neighbourhood may be "better" than other choices, in the sense that the resulting rulestring would become shorter / easier to read and understand.

At least in the case of the rule "particles", the alias should be deleted, and the rule table should be retained. The INT alias comes from this very short thread where it was never actually used as the rule name in any RLEs. By contrast, there are several RLEs using the rule table variant. "particles" is also in the rule table repository, so anyone using that would encounter problems posting their "particles" patterns to the forums.

There are three related items:
  • Pixel Ratio is the ratio of the resolution in physical pixels to the resolution in CSS pixels on the current device. See here for more information. It is typically 1 for normal screens and 2 for high DPI screens. However, if you scale the browser window this will change.
  • Scale is the scaling factor that LifeViewer applies to the PopUp Viewer window. It will be the same as Pixel Ratio unless that makes the Popup Viewer too big to fit in the browser window, it which case it will be reduced to compensate, but never less than 1.
  • Window Zoom is typically 1, but will be less than 1 if the Pixel Ratio is so high that a Scale of 1 is not enough to fit the Popup Viewer in the browser, in which case it will be less than 1.
I can reproduce the "hexagonal period map breaks when changing zoom" on desktop by doing these things (my monitor is 1920x1080 so you may want to change some values on your end if yours isn't):

- Enter the browser advanced settings page (this is about:config on Firefox and derivatives)
- Change the value of layout.css.devPixelsPerPx - in my case, setting it to 1.2 worked. You'll want "Scale" in Help > Info > Display to be a different value when the browser window is maximised versus minimised.
- Identify an oscillator in a 2-state hexagonal rule
- Minimse and maximise the window repeatedly

Something I've wanted to request for a while: could we have some way of customising rulestrings visually, for isotropic non-totalistic rules on the square grid and hexagonal grid? A lot of newer members in the community might not remember the full table, so some way to visually see what transitions are selected and what isn't would help a lot with that. In addition, I find being forced to open a text box and change characters in the rulestring just to toggle one transition quite frustrating, so a change like this would streamline manual rulegolfing considerably.

Life32 had a system like this:
image.png
image.png (25.51 KiB) Viewed 4279 times
Each transition icon can be toggled on or off to add the transition to the current rule, or take it away.

Along with the standard Moore and hexagonal neighbourhoods, this could end up being a useful asset if other isotropic non-totalistic rulespaces end up being implemented (such as the ones CAViewer and lifelib support), since those will obviously be very new to most people in comparison.

Is this something others here would like to see?

I don't think a visual UI would streamline rulegolfing. That is going to result in too many UI actions (mouse clicks, key presses, etc.)
It's much faster and easier to edit the rulestring (or the @RULE file) directly, than to go back and forth between the pattern and the visual CA definition editor dialog.

Especially when you're mentioning "other isotropic non-totalistic rulespaces". A visual UI is going to be unfeasible (and not merely inconvenient to use) for larger rulespaces.

What could help is having the rulestring edit box in the same window as the pattern. Instead of going to a separate dialog to edit the rulestring, you could then simply edit the rulestring.

Within LifeViewer, there may not be enough screen space to implement any of the above.
Within Golly user interface, an additional UI panel with a rulestring editor could be possible, without eating too much screen space.

To be clear, this would be an optional alternative to the current system; editing the rulestrings manually would remain as an option.

This could depend on how big the embed or popup actually is (like how settings is disabled for small windows) but I think this is entirely doable. A visual example will come hopefully soon.

My point remains.
Too many UI actions (switch to the editor, click, type, click, type, click, type, switch back to the pattern, play, undo, switch, click, type, switch, etc.)
Significant complexity to be added, with potential of causing various kinds of interesting bugs and user experience issues, and without clear benefit over what is already available.

No, simply writing three distances between parallel lines does not capture the "bounding shape".

The following two patterns on the hexagonal tiling have two different "bounding shapes" in the above sense (intersections of "half-planes"), but the distances are the same in both cases:

You can combine the six inequalities into three double inequalities, on x, y, and x - y respectively:

Code: Select all

x_min <= x <= x_max
y_min <= y <= y_max
xmy_min <= x-y <= xmy_max
This is analogous to describing the bounding rectangle of a pattern on the square tiling using two double inequalities (x_min <= x <= x_max, y_min <= y <= y_max).
