问题 Mr. Dum: Hello, I'm very stupid but I still want to solve a 3x3x3 Rubik's cube. Mr. Smart: Well, you're in luck. Here is guidance to do just that! Mr. Dum: No that won't work for me because I'm Dum. I'm only capable of following an algorithm like this. pick up cube look up a list of moves from some smart person while(cube is not solved) perform the next move from list and turn the cube as instructed. If there are no more turns in the list, I'll start from the beginning again. hey look, it's

Easiest to code algorithm for Rubik's cube?

问题 What would be a relatively easy algorithm to code in Java for solving a Rubik's cube. Efficiency is also important but a secondary consideration. 回答1: The simplest non-trivial algorithm I've found is this one: http://www.chessandpoker.com/rubiks-cube-solution.html It doesn't look too hard to code up. The link mentioned in Yannick M.'s answer looks good too, but the solution of 'the cross' step looks like it might be a little more complex to me. There are a number of open source solver

Using Dictionaries in Python in place of Case/Switch statement

问题 I want to randomize a rubik's cube that is initialized as complete (all colors on the correct sides). I have move functions that rotate the cube. I want to randomly pick 50 functions in a row to properly randomize it. I am doing this project to learn a little bit more about Python, since I mostly do C++ and I see there is no case/switch for Python, so I am trying a dictionary. When I make the dictionary, the code seems to execute for some reason: def random_cube(self): scramble = { 0 : self

How to add listeners to Swing components in Scala?

问题 I'm trying to implement the MVC design pattern in a Rubik's cube Scala application. In Java, I would do this by adding an ActionListener to the buttons with the listeners in the controller class. In Scala, I've found this extremely difficult. Can anyone give me some examples of how to do this? 回答1: You can of course do it in the exact same way as you did in Java. Using Scala however, you can also use the Scala swing library to do this, which provides a set of wrappers around the Java Swing

问题 I am writing my own 'Rubik's cube' application. The main class Cube has 18 rotation methods: RotateAxisXClockWise, RotateAxisXAntiClockWise RotateAxisYClockWise, RotateAxisYAntiClockWise RotateAxisZClockWise, RotateAxisZAntiClockWise RotateUpperFaceClockWise, RotateUpperFaceAntiClockWise RotateFrontFaceClockWise, RotateFrontFaceAntiClockWise RotateRightFaceClockWise, RotateRightFaceAntiClockWise RotateBackFaceClockWise, RotateBackFAceAntiClockWise RotateLeftFaceClockWise,

Python 3.2.1: exec('x = y()') sets a value in a toy example, but not in the full code

问题 I'm using an exec() statement to set a value, like so: foo = 3 def return_4(): return 4 instruction = 'foo = return_4()' exec(instruction) # <---- WHERE THE MAGIC HAPPENS print(foo) This comes out as 4, as I expect. My program has operations for manipulating a Rubik's cube. In this stripped down version, I'll do four things: I'll instantiate a cube, filling in one face (with abbreviations for 'front top left' and 'front bottom right' and the like). I'll have a function that rotates that front

Rotating faces Rubik's Cube C#

问题 I've been looking around the internet for a few days now, and I can't really find an answer that i can understand well enough to rotate my Rubik's Cube. I have made my own 3D Model using Blender of a Rubik's Cube and imported it in to Unity which is what I'm going to use to rotate the faces. But I just don't seem to understand the mathematics involved in rotating a Rubik's Cube, should i use Matrices? If so how do i couple it all together for it to work? I can rotate a single side around by
