Another thing that you could use to perform 3d rotations is quaternions. They are 4d numbers designed specifically with the idea of performing rotations in 3d space and are relatively easy to pick up. 3B1B had an awesome video about them and I think it would be very interesting to see quaternions in action

[@ffggddss]

Yes. SO(3), the rotation group in 3-space, has 3 dimensions; quaternions have 4. So the quaternions used for this are those that are unit length; i.e., the sum of squares of the components = 1. That constraint takes away 1 degree of freedom, leaving 3, to match SO(3). And the correspondence is 2-to-1, where any given quaternion and its negative both give the same 3-space rotation. Fred

[@djsyntic]

Near the end of the video, you set up Sequence with a random set of 10 moves in a loop with Sequence += blah. Then you set up a second loop that takes Sequence and reverses it into NextMove. But this seems silly to me to have two loops. You could do this all in the first loop with these lines: if (random) // rotate clockwise Sequence += blah NextMove = blah.UCase + NextMove else // rotate counterclockwise Sequence += blah.UCase Nextmove = blah + NextMove

Here's a suggestion. There are actually infinitely many possible quads for any given normal, but we want those that "look right" for the problem at hand. We can think in terms of a spherical coordinate system to help us here. function DrawCubieFace( PVector n) { // Let's compute a few vectors using the cross product function for PVectors. // assuming that PVector n stores the normal vector. PVector axis = new PVector( 0, 0, 1); // unit vector along z-axis, also the spherical coordinates polar axis PVector lat = n.cross(axis).normalize(); // we compute a unit vector that is tangent to a "fixed latitude" circle, and perpendicular to n PVector lon = n.cross(lat).normalize(); // ...and a unit vector that is tangent to a "fixed longitude" circle. // The corners of our quad can be found by using the lat and lon PVectors // TODO: translate the result let s = 1; // length of the sides fill(255); // TODO: pick the right color here beginShape(); // Start from the center. PVector v = new PVector(0, 0, 0); // First corner v.add(PVector.mult( lat, s*0.5)).add(PVector.mult( lon, s*0.5)); vertex( v.x, v.y, v.z); // Second corner v.add(PVector.mult( lat, -s)); vertex( v.x, v.y, v.z); // Third corner v.add(PVector.mult( lon -s)); vertex( v.x, v.y, v.z); // Last corner v.add(lat); vertex( v.x, v.y, v.z); endShape(); } Disclaimer: I wasn't able to test this one. Debugging might be required.

I don't think you got all the CW and CCW turning correct. If you to 39:00, you are turning opposite faces in the same direction which means that one is CW and the other is CCW. And it looks like you carried this minor bug through to the refactored switch code. Shouldn't be too hard to fix though. Just need to flip the direction on half the turns.

[@harjitsingh7308]

Technically does the same thing. I don't see that much of a problem in doing so (then again i don't know too much about time/space complexity maybe there is a downfall there between both methods)

[@rhysperry111]

Harjit Singh the main reason a switch statement is better is because it is easier to read. I’m not sure about this but it is probably also better optimised.

[@Bunny99s]

@@rhysperry111 Actually I don't agree on the readability statement. Switch statements are usually not really that easier to read. They are quite nice for two reasons: You can actually have a complex calculation inside the switch() which will be calculated once and then compared. Of course this can also be achieved with a local variable so not really a strong argument. The second reason which is the most important one is that depending on the language and implementation you usually get a performance gain if you have many switch cases. I'm not really using Java (or processing) but I know exactly how C# implements switch cases. If the actual case values can be arranged in a certain order and don't have too large gaps, the compiler simply makes a jump table and uses the switch argument as index. If there's just one huge gap it might split it into two jump tables. If all values are a fix amount apart it might use some preprocessing math (like dividing the value by 4). If nothing helps and the number of cases is rather small, it just creates an if else chain. If the case count is high enough it actually uses a hashtable lookup to convert the values into an integer and use that in the jump table. C# doesn't allow fall through except a case is empty. So it's essentially just two case values merged into one. As far as i know Java does allow fall through just like C / C++. However this doesn't really help the readability and might enforce some strange ordering of the cases. Also it's a mess regarding scope since the whole switch body is one scope so you easily get issues with local variables. Adding curly braces to each case does not only make it even longer, but also terrible to format in a nice way. For "relatively" small if else chains they are usually shorter and easier to read. For example having only one statement in each if body allows you to write one elseif in one line. The different conditions nicely align and the actual executed statements align nicely. For example have a look at the input processing for my Rubik's Cube in the Update method. This btw is a complete Rubik's cube done in 300 lines in Unity3d: www.dropbox.com/s/gyif5k3y0w4n68d/RubikCube.cs?dl=0 I've done this somewhere in march 2018 for fun^^. Usually I love to create things procedurally but in this case i just used 27 of Unity's default cubes. Just make sure you use a shader that uses vertex colors.

[@josgielen8524]

Solving a Rubik's cube with a standard genetic algorithm seems pretty hopeless. I tried several variations but it just cant solve any scramble that needs more than 6 rotations. A few observations: It was proven some years ago that every scramble of a 3X3X3 cube can be solved with maximum 26 quarter turn rotations. A 'DNA' with a fixed number of rotations (e.g. 26) does not work. For example: if the DNA length is 15 then the cube could be solved after 10 rotations and the next 5 just scramble it again. I calculated the fitness of each individual after each rotation and used the part of the DNA that resulted in the highest fitness. But Crossover of this best DNA or of the entire DNA does not seem to work very well here. A complete random DNA in each generation actually got better results in my tests. Anyone got any ideas what could work better here?

[@ErikWouters]

To make the problem simpler I would not allow the algorithm to do any move (at least not before you have working proof of concept), but rather make it pick from four options: - Rotate 3 corners - Rotate 3 edges - Flip 2 corners - Flip 2 edges There are easy algorithms to do these basic moves. You also need to pick the side you do this algorithm on (1 of 6) and the side of the cube you keep as the top when you do this algorithm (1 of 4). This is quite similar to how most blindfolded cubers solve their cubes. As a fitness function I would take whether the cubie is oriented correctly and how many spots it is from where it needs to be. I'm not very familiar with genetic algorithms, but the 'DNA' would need to store the ability to do multiple moves before a re-evaluation of the fitness of the cube (unless you use setup moves) because some configurations require to move a cubie to the other side of the cube. All four suggested moves are completely independent, so the 'DNA' can does not need to do everything right before learning something.

[@TheCodingTrain]

Thanks for this thread! I haven't tried yet but this is super useful info.

[@georgechristoforou991]

DNA of cube matches + cube moves would improve a GA . So you have a string of partial matches of the cube and a string of rotations. mutate the rotations list only. Also do it as a set of goals such as bottom then middle then top of cube.

[@ffggddss]

​@@TheCodingTrain If you're going this deep, you may want to check out David Singmaster's booklet, _Notes on Rubik's Magic Cube,_ 1981. Singmaster was a lecturer in mathematical sciences & computing at the Polytechnic of the South Bank in London (now the London South Bank University). During the time Singmaster was accumulating these Notes, his office-mate, Morwen B. Thistlethwaite (no kidding!), was using his computer to search for "processes" (sequences of cube moves) that would efficiently solve the cube; and ones that would solve certain configurations of the cube. None of MBT's computer algorithms were detailed, or even described in the Notes, but it's possible that a net search might turn up something useful. Some of the processes he discovered this way, are given in the Notes. One of the most interesting features of the MBTC (MBT's Computer) solution processes was that, contrary to the vast majority of (human) cubers' solution methods, his would not appear to be making any progress until the last few moves, when everything would suddenly fall into place. It seems likely that the "ideal" solution would work this way. Main point is, this is a longtime, well-trodden problem, and there are bound to be lots of interesting ideas out there for how to do this (which, BTW, I'm not at all plugged into). OTOH, if your purpose is to work out your own method, independent of prior work in this area, I completely understand and support that. It'll be good to see what you might come up with. Fred

[@ffggddss]

@@ErikWouters Those four processes are, of course, essential to solving the "top layer," once the other two layers are done (which is relatively easier). I trust that by "rotate," you mean cyclically permute, without changing the "orientation" (the facelet within the top layer) of the pieces. Also note that, while edges are said to "flip" (between 2 possible states), corners "twist" (having 3 possible states). When a pair of corners twist, they must do so in opposite directions. A fifth possible top layer process is a tri-twist, where 3 corner pieces all twist in the same direction. These two moves have been nicknamed, "meson" and "baryon" moves, respectively; with a single corner twist (impossible in isolation) being analogous to a "quark." Fred
