You need to provide some arguments/thoughts/proof sketches, otherwise it is just a collection of, at best, observations, and at worst, random statements.

I did some simulations of how random perturbations spread through dense random fields. I filled a board with random state of density 0.5, waited for convergence, and then repeatedly perturbed a 100x100 square in the center, filling it again randomly with density 0.5. After each perturbation I waited ...

dvgrn,
I see now that the original premise that an isolated, local attack will stay local is wrong. Any isolated attack has the potential to turn into a blob of unpredictable things that may grow quadratically through empty space, and should be treated as such.

In this case I also see now that the ...

the highest-probability chain reaction is very likely going to be something that you don't know about -- i.e., in practice it can only be discovered by experiment
The idea was that a chain reaction involving many layers is impossible, given that all layers are random and assuming there is no ...

Thank you for the reply.

In your other post you wrote that an active repair mechanism is more vulnerable to attack than a passive barrier. Let's consider a defense against gliders. The active defense can be broken only if another attack comes while the damage from the previous attack is not yet ...

I am new to this forum, apologies if this has been already discussed.
I am interested in patterns that are resistant to damage from the outside, or from one side - for example, if a spaceship collides with it, it restores itself after some time. If I understood the state of the art correctly, it is ...
