Dominoes, an ancient toy. Today we are going to look at the problem of Domino coverage:We have a 2xN strip board and then use the 1x2 dominoes to cover the entire board. How many different coverage methods are there for this chessboard?For example, for a board with a length of 1 to 3, we have the fo

In a checkerboard composed of 2 ^ K * 2 ^ K squares, if there is a square different from other squares, it is called a special square and changed to a special checkerboard. Obviously, there are 4 ^ K positions in the special square on the board. Therefore, for any k> = 0, there are 4 ^ k different special chessboard. The special checkerboard shown is one of the 16 special che

When it comes to the history of home consoles, it should go back more than 40 of years. At the time, the world's oldest video game maker, Atari, launched a home console version of Home-pong (1975) based on its arcade (not at home, but on a commercial game console installed in the arcade). This is a two-player tennis game, the content is actually very simple, is in a pure black background with a white rectangle to represent the racket and the ball.However, for the people at that time, to be able

The first one, technological change. Second, meaning change. They give examples of ga

On the internet to see a recursive solution to the courseware, the feeling inside the problem is classic and interesting, layers of progressive, so here to record.1. There is a circle and N lines on a plane, each of these lines intersects with other lines within the circle, assuming that no three lines intersect at a point, how many areas the lines divide into.2, there are n lines on the plane, ask these polylines can divide the plane into how many blocks?

This article will introduce the amazing Aztec diamond model. I think this is a question that can be entered into the "Mathematical book". Its Expression is simple and elementary, but it is closely related to many of the most profound and wonderful questions in the counting combination, of course, it also has an amazing solution. I can't help but write it out and share it with you.
So what is the Aztec diamond model? Very simple: Stack $2, 4, \ cdots, 2n $ squares in sequence, and then perform an

Description Xiao Ming and Xiao Hong often play a game. Given an n × n board, a stone is placed in the upper left corner of the Board. They move stones in turn. In each round, a contestant can only move the stone up, down, left, and right to a grid, and cannot be accessed before moving it to the grid. No one can move the stone. If James first moved the stone and both contes
This time we will introduce a classic problem in the counting combo: dimer lattice model. The question is: How many different dominoes are there for a 64-square chess board? Here, the covering refers to covering the entire board without repetition or omission.
It is a possible method of overwriting (the picture is from Wikipedia ):
The answer to this question is 12988816. A very large number is definitely not counted one by one. In 1961, German
"Problem description"In a chessboard of 2^k * 2^k squares, if a square is different from other squares, it is called a special square, which is called a special chessboard. It is obvious that special squares appear on the board in the 4^k case. Thus for any k>=0, there are 4^k different special chessboard. The special chessboard shown is one of the 16 special chessboard in k=2.Figure AIn the board coverage problem, the different forms of the L-type dominoes
