How real was the anxiety over a domino effect rolling in from the rebellious satellites?
If vi > 2 and hi > 2, then we can place either a vertical or a horizontal domino on the step, so we do both.
Now, we have to ensure that each safe partial tiling appears exactly once in the tree, so two distinct tilings mustn't give the same result by adding dominoes.
The problem is with vertical dominoes only.
Initially, the states of dominos are unknown.
If there were a beginningless series of falling dominoes, would not the number of dominoes fallen prior to today be actually infinite ?
The tiles are dominoes composed of two unit squares; there are just two tile types.
Games like dominoes and draughts can help both perception and memory.
