Random walks on the STOMACH graph.


Suppose we start at a tiling, say, the one on the right.

At each step, we flip a coin and with equal probability choose an adjacent tiling one move away.

How many steps does it take to reach a "random" tiling?

We have computed the eigenvalues of the Laplacian of the STOMACH graph which can help solve this problem.

The spectral gap is 0.02573644110. This implies that in roughly 39 (~ 1/0.02578...) moves to reach a "random" tiling.

More to come.
