Triomino induction
WebThen our 2 n × 2 n checkerboard with one square remove is exactly one right triomino. Induction: Suppose that the claim is true for some integer k. That is a 2 k × 2 k checkerboard with any one square removed can be tiled using right triominoes. Suppose we have a 2 k +1 × 2 k +1 checkerboard C with any one square removed.

WebJan 22, 2024 · It is trivial to rotate the figure by 90 degrees, 180 degrees or 270 degrees, and to flip left-to-right or up-and-down, thereby covering all component squares in the full grid. If that isn't "trivial," it is hard to know what would be. – David G. Stork Feb 1, 2024 at 2:10 Add a comment You must log in to answer this question. WebA triomino is a shape of the following form: In the lecture, we proved by induction that every board of 2^n times 2n squares with one corner removed admits a tiling by triominos. For every natural number n, let T(n) be the number of trionimos used for the tiling of the board of 2^n times 2^n squares with one corner removed.

WebHe proves by induction that any such square grid with one square 'blocked in' can be tiled using triominos. The python code in this repository acts as a 'computational proof' of the claim. The code follows the inductive proof (specifically the top-down approach) introduced by Professor Erickson.
WebReview: Proof by Induction. Let n be a natural number. Show that P(n) is true: for every checkerboard with one square removed can be tiled using right "triominoes" Basis Step is true, as a 2 × 2 checkerboard can be covered by a triomino. Induction Step A triomino is a flat L shape made from three square tiles. A board is divided into squares the same size as the tiles. The board is 2n 2 n by 2n 2 n squares. One square, anywhere on the board, is coloured blue. We can put triominoes on the board, but they must not overlap and must not cover the blue square. See more When n=1n=1, we have a 22 by 22board, and one of the squares is blue. Then the remaining squares form a triomino, so of course can be covered by a triomino. See more When n=2n=2, we are considering a 44 by 44board. We can think of the 44 by 44 board as being made up of four 22 by 22boards. The blue square must lie in one of those 22 by 22 … See more We can continue in the same way. For example, to show that we can cover a 6464 by 6464 board, we’d use the fact that we can cover a 3232 … See more We have an 88 by 88 board, which we can think of as being made up of four 44 by 44 boards. The blue square must be in one of those boards, and as above we know that we can then cover the rest of that board with triominoes. That … See more

WebA triomino is an L-shaped domino tile as pictured: Figure 1: A triomino. A grid of squares can be tiled with triominos if one can place a collection of triominos onto the grid so that each square is covered by exactly one triomino.
