Polynomial gun and cumulative sum generator

Posted: February 22nd, 2017, 2:26 am
by gameoflifeboy
I have constructed a device that takes in a stream of gliders, emitted (or at least passing by a given point) at generations x0, x1, x2, x3... and returns a stream of gliders at positions n, n + x0, n + x0 + x1, n + x0 + x1 + x2...

The values x0, x1... must be multiples of 960. Part of this is due to the fact that the glider duplicator is P30, but even if it is replaced with a stable mechanism, the values still need to be multiples of 64.

Here is the device inputted with 960*2, 960*3, 960*5, 960*6.

Code: Select all

Starting with a gun as input, patterns can be constructed that emit gliders at time t = 960*p(n), where n is a non-negative integer and p is any polynomial such that
  • the values p(n) (but not necessarily the coefficients) are integers for integer values of n;
  • values of q0(n) = p(n+1) - p(n), q1(n) = q0(n+1) - q0(n), q2(n) = q1(n+1) - q1(n), etc. are all positive, unless q(n) = 0 for all values of n. (If p(n) is increasing, this must be true for p(n + a), for a sufficiently large value of a.)
Here is an example pattern, the cube gun. It emits a glider in the lower right corner at t = 960*n^3 + 493, for non-negative integer values of n.

No, but it does seem similar. Before I made it, I was looking for a way for a gun to shoot a particular polynomial sequence, but constructing it from the polynomial term by term seemed too hard. So I used my years of experience constructing sequences from their differences to make a pattern that did the same thing.

I just updated my script to clear the canvas before placing the pattern.
