Since April 1st.

This rotor is known, but your stabilisation is better than the one in the collection.

More oscillators, none of them stabilised. p14 (I am not sure that it doesn't belong to some extensible family): x = 13, y = 26, rule = B2/S234 obo6bo2bo$ob4ob2obo$obo2b2o3bobo$obobo2b3obo$obo2bobo3bo$ob4ob4o$obo7b obo$obob7obo$ob2o6b3o$o3b2ob3o$ob3obo2b2obo$o3bo6b2o$o3b7o$o2bo4bobobo $o3bobobobobo$...

Here is a small example in B2/S234:

I guess the viewer should not try to open this.

I don't know what diagonal takes are, but c/12 diagonal rakes can be found here:

why would you exclude p10 amd p15 as "uninteresting? Wouldn't you rather exclude oscillators instead? All small ship with period > 4 are interesting! The C program (as well as my version 0.4) distinguishes oscillators and spaceships. The criteria I presented in my previous post should only be used ...

Thank you all!

I have done a small one.

To simeks & everybody: I performed the following searches using C version of CopperSearch: o1 0123 4567 89ab cdef ghij klmn opqr stuv .... stuv opqr klmn ghij cdef 89ab 4567 0123 o2 0123 4567 89ab cdef ghij klmn opqr stuv stuv opqr klmn ghij cdef 89ab 4567 0123 o3 0123 4567 89ab cdef ghij klmn opqr ...

Cool, that's a pretty rare pattern:

This gives different results in your & my programs:
I think that this is probably a feature, not a bug, but I want to make sure.

Firstly, thank you all.

Secondly, given the abundance of octagon 2 + some p2 combinations, you are not required to report them any more.

The bug is fixed in version 0.4. Happy searching!

Version 0.4

This version fixes a nasty bug which was present in v0.3. Please upgrade.

There seems to be an error with v0.3. Please wait until I sort it out.

An awful lot of spam here.

For those who don't read the main CopperSearch thread: please upgrade to v0.3.

Version 0.3. This version has a bug, so please do not use it.
Advantages over v0.2:

• Approximately an order of magnitude faster.
• Much more user-friendly.
• Distinguishes oscillators and spaceships.

How fast is it?

You can minimize it but not close.

Thank you for your replies. I have just run a small side-by-side comparison of static and dynamic arrays. Static arrays are almost exactly 1.5 times faster, so the next version of CopperSearch will use those. Delphi sorted lists are an easy hack, but they are classes and therefore they are almost de...

Thanks for doing this. Out of curiosity, what is the rationale for throwing away period 8 and period 15? Also, how much would it speed up the search to skip step 1, and do you think it might be worth it? The search with diagonal symmetry finds a figure eight approximately once every two seconds. An...
