What are the characteristics of an Abelian Sandpiles for a grid 3 x 3?

QUESTION

Iterating in a python numpy matrix - adding and subtracting to cell elements gone wrong

Asked 2021-Dec-14 at 08:57

Input is a numpy matrix and the procedure is to find all entries above 3 in the matrix. When the program has found an entry with a value of 4 or higher, the program must subtract 4 from that matrix position and distribute that 4 - one to the cell above, one to the cell below, one to the cell to the left and one to the cell to the right.

Input is [ [3,3,3], [3,4,3], [3,3,3] ], and I expect an output of [ [3,4,3], [4,0,4], [3,4,3] ].

Instead I get [ [3,4,4], [4,2,1], [4,1,1] ]

The 4 in the middle of the input matrix needs to be taken out and redistributed to the adjacent cell elements of the matrix; one above, one below, one to the left and one to the right. This does not happen. I cannot make sense of it. Anyone, please.

I added some constraints - so that if an entry in the matrix does have an entry of 4 or larger close to the boundary of the matrix - this will make sure that you add one only to existing entries in the matrix.

Here is an implementation using np.where and assuming periodic boundaries. If you want the additions to 'leak' out of the matrix you have to filter out the right, left, top, bottom conditions accordingly.

QUESTION

Python - numpy arrays - Abelian sandpile

Asked 2021-May-22 at 12:01

I'm trying to do the Abelian sandpile model using a simple numpy array.
When a 'pile' is 4 >=, then it collapse among its neighbors.
I understand how the "gravity" thing works, but I can't think of a way of making it.
Here's the code to make my array :

Use np.divmod to identify where the cells tumble and how much tumbles. Then use array slicing to shift the amounts tumbled and add back into the sandpile.

QUESTION

What are the characteristics of an Abelian Sandpiles for a grid 3 x 3?

Asked 2020-Aug-15 at 13:46

I have a C project which involves Abelian Sandpiles. The issue is, after a few days of research, I am still struggling to understand the characteristics of a Sandpile.

Our project instructions are:

Write a function that computes the sum of two sandpiles

A sandpile is considered stable when none of its cells contains more than 3 grains
When your function is done, grid1 must be stable

The function returns void and takes two int parameters int grid1[3][3], int grid2[3][3].

An example of the expected output is:

Just by looking at your grids, I think it works like this:

If a cell is stable (... <= 3), it does not lose any grains. If it is unstable (... > 3), then it will lose a grain to every stable neighbour cell. The corner cells will, if unstable, always lose 2 grains (they "fall off the board"). Similarly, the cells on the edge will, if unstable, always lose 1 grain (it "falls off the board").

This algorithm is performed for each cell of the original "input" grid; therefore, the order should not matter.
