4x4x4 parity algorithms

From Speedsolving.com Wiki
Revision as of 22:31, 5 January 2018 by Cmowla (talk | contribs) (Did some spacing fixes between two sections and updated the introduction. For the algorithm bars, I removed the video cam icons and also have added in many links to forum posts to give the historical date and context in which an algorithm was created.)

Parity (also known as Orientation Parity and Permutation Parity) on the 4x4x4 is situation (occurring in 3/4 of all solves) commonly identified when only two or four edge pieces need to be cycled in order to complete solving the 4x4x4 or at least successfully bring the 4x4x4 into a pseudo 3x3x3 state. However, as is shown on this page, parity cases can take many other forms.


This page attempts to list all efficient algorithms for every common form of parity as well as those only common in specific solving methods. Solutions listed which are not as efficient as others in their categories are at least relatively efficient for their specific effect on the cube or for the move set they are confined to.

Introduction

The shortest 4x4x4 cube odd parity fix which preserves the colors of the centers (PLL Parity algorithms are even parity fixes for wing edges) is:

(Thanks to the work of Tom Rokicki and Ed Trice in 2014.)


The shortest (and well-known) nxnxn cube odd parity fix which preserves the colors of the centers is simply:

Speedsolving Logo tiny.gif (13,9) (2R U2)4 2R

For those who are familiar with commutators and conjugates, this quick nxnxn cube parity fix can be represented as [2R: [U2, 2R] [2R2 U2: 2R] ]. In fact, we can do the same 4-cycle of wing edges with just one conjugate [2R2 2D' 2R2 u2 s': 2R'].


One of the simplest center color and dedge preserving odd parity (OLL parity) algorithms to remember also contains a repeated sequence:

The phrase "there is more than one way to solve any given problem" holds true with tackling 4x4x4 parity situations. In fact, there are different categories of parity algorithms, and algorithms can consist of different move patterns (the move set of one algorithm might be entirely different than the algorithm above and/or below it). This page not only contains commonly practiced speedsolving algorithms, but it also contains algorithms which illustrate the veracity of the 4x4x4 cube parity algorithm domain.


NOTES

  • All algorithms are in SiGN Notation
  • Some algorithms have been named, and their names are in the first column.
Names such as "Alg(v1)", "Alg(v2)" are not actual names: they are just a notification that consecutive ordered version algorithms are different versions of the same algorithm.
  • The algorithms below each case image solve the permutation in the case image.
  • All algorithms' lengths are written next to them (slice quarter turn, slice half turn).
Algorithms with fewer slice half turns (STM) are listed first in each category.
Algorithms which have fewer slice quarter turn moves (SQTM) are listed before other algorithms which have the same number of STM as them.
  • Most of these algorithms affect centers on the 4x4x4 supercube: not all algorithms affect the supercube centers in the same manner.
  • All algorithms can be applied to the 6x6x6 if instead of turning the outer 2 layers, turn the outer 3 layers; instead of turning 1 inner layer slice, turn 2 inner layer slices.
  • There are links to either forum posts or video urls in the right-most column for some algorithms. These links are intended to either show one of the (if not the) first place the algorithm (or a simple conjugation, transformation, and/or a directly related version of it) was first published, and/or they show one of the (if not the) earliest date of publish.

Pure Flips/OLL Parity Algorithms which Don't Preserve the Last Layer

  • If all inner slice turns of the algorithms in this section are converted to wide turns, the algorithms will simply affect more pieces in the last layer.
  • The maximum number of wide turns are used in each algorithm to do pure flips to allow the easiest execution possible (with the exception of the 15 STM solutions), but no extra outer face turns are included as to make any algorithm longer (in STM or SQTM) than what it is without any inserted face turns at all.
  • Of course, all wide turns may be converted into inner slice turns to achieve the same pure flip result.


OLL Parity (Only)

One Dedge Flip.png and Non-Pure Single Dedge Flip.png


15 STM Solutions

  • All possible 288 algorithms which flip the upper front dedge are listed and rigorously categorized below.
    • For the sake of conciseness, note that, for example, Alg.1(v1) is a transformation of Alg.1(v2), Alg.1(v3), Alg.1(v4), and Alg.1(v5).
    • In general, any given algorithm in any subgroup is a transformation of any given algorithm in another subgroup which is in the same group.
    • This was proved directly (in WCA notation) by Christopher Mowla in 2012.

23 Single Slice Quarter Turn Solutions

  • The 53 23 single slice quarter turn solutions listed below contain at least some quarter face turns as opposed to the (25,15) solutions above.
  • Additional unique 23 single slice quarter turn pure one dedge flip solutions can be created from all these by doing one of the following, but note that no additional inner slice turns may be used in the resulting algorithms more than what is already used in these solutions.
    • If the algorithm contains face quarter turns with inner l and r slices in between them, invert all face quarter turns in the algorithm.
    • If the algorithm contains face quarter turns with u, d, f, or b slices in between them,
      • Invert all face quarter turns in the algorithm
      • Convert u inner slice turns to d inner slice turns (and vice versa) OR convert f inner slice turns to b inner slice turns (and vice versa). Do not invert these turns, just substitute.
  • Like the (25,15) solutions, these solutions have been grouped next to their transformations. To save space, we label each group's algorithm as Alg(v1),Alg(v2),Alg(v3), and so forth.
  • These are most likely not all of the possible 23 single slice quarter turn solutions. Perhaps in the future, we will have efficient optimal solvers in the single slice quarter turn metric for which we can use to extract all possible solutions.
    • Since there is currently one 23 single slice quarter turn algorithm listed in the previous category, and since we can create an additional pure dedge flip algorithm from each of the following 53 solutions, we effectively show 107 unique 23 single slice quarter turn solutions on this page.
  • Lastly, it's worthy to note that using the classic setup through depth 18 of single slice half turns, the following 21 slice quarter turn algorithm was the only 21 slice quarter turn 3x3x3 algorithm which was closest to being a single dedge flip algorithm. Perhaps if the classic setup is used up to depth 21, some 21 slice quarter turn solutions may be found, but, as of yet, 23 is the current upperbound.

Algorithms of this category which are not optimal (in either single slice metric)

  • The following list of algorithms are all unique solutions generated with the classic setup which use only 2 different face turns which are at most 27 single slice quarter turns and 18 single slice half turns.
    • There is only one algorithm which just uses the face turn, U2.
  • Like the (25,15) solutions, all solutions ending in B2 may be conjugated with B2 to create a handful more "unique" algorithms.
    • All other algorithms can be modified by inverses, mirrors, cube rotations, or a combination of any of these to create every possible algorithm which uses 2 faces which are generated from the classic setup.
  • Since this is a large set of algorithms,
    • None of these algorithms have any wide turns in them (despite that some algorithms can have some).
    • Even though it is very likely that algorithms related by transformations are listed next to each other, no official sorting by transformations was done.
  • Since these algorithms use either U and F faces or U and B faces, all algorithms which affect one or the other have been grouped together for convenience of personal preference.

OLL Parity algorithms Which Don't Preserve the Last Layer

ImpurededgeFlip.PNG

OLL Parity (Only)

  • Note that, unlike the previous section, none of these are pure flips if wide turns are converted to inner slice turns.

1 Flip

  • With the exception of Kåre Krig's 2 gen algorithms, all algorithms listed in this section were derived from algorithms in the previous section by using 4x4x4 wide turn equivalencies such as r = (l x), l2 = (r2 x2), etc.
    • Specifically, these algorithms were derived from the classic setup's solutions which are at most 18 single slice half turns. They only involve 2 face turns and thus they are additional transformations which are "legal" in wide turns, but "illegal" transformations to keep these algorithms pure dedge flips.
      • Therefore we have more 15 STM solutions which preserve F3L in wide turns than we have for pure dedge flips, for example.
      • Most of these algorithms need to be adjusted to work on 5x5x5.
  • Lastly, it's interesting to note that the following algorithm cannot even be used to solve OLL parity if all of its wide turns are converted into single slice turns.

  • You can make a 3 flip from a one flip, for example, by conjugating a 1 flip with B' R'. For example,

  • For other algorithms for OLL + OLL Parity (that is, using outer layer turn setup moves to algorithms like those in this section (and algorithms in the previous with wide turns), see Michael Fung's old page and this thread.


OLL Parity Algorithms Which Don't Preserve F3L

  • One advantage to having access to algorithms which don't preserve the first three layers of the 4x4x4 is that the shortest algorithms that this category of algorithms has to offer have fewer moves than algorithms which preserve the first three layers, which might be of interest to certain cubers.
  • Unlike algorithms which preserve the first three layers, which are at minimum 14 block half turns (double parity) and 18 block quarter turns (one dedge flip), some algorithms in this section are just 13 block half turns and some are just 15 block quarter turns.

  • It's interesting to note that the long (u,U,2R,2L,m) algorithms have the same structure as Bruce's (15,15) OLL parity (only) solution.


  • To see more detailed information on how most of the short algorithms were found, see Bruce Norskog's post.
  • To see Stefan Pochmann's explanation of his Petrus Parity Algorithm, see his old post on Yahoo Groups.
  • To see a large list of (U,r,R) solutions (several of the algorithms in this list are listed in this section already) that have been found by Kåre Krig, see this thread.


Non Dedge-Preserving Last Layer 2-Cycle Cases

  • This section contains all of the 2-cycle cases that can occur in the last layer besides the one dedge flip.
  • These are additional cases which arise in the K4 Method and other direct-solving methods.
  • Algorithms marked as "Safe" are supercube safe.

Summary of Last Layer 2-cycles and 4-cycles (in two dedges) Movecounts

  • Since there is disagreement among cubers about whether lowest slice quarter turn moves (SQTM) or lowest slice half turn moves (STM) defines the "optimal algorithm", the table below categorizes all 2-cycle and 4-cycle cases (in two dedges) on the 4x4x4 by the average of the two.
  • Algorithms optimal in STM need not be the algorithm with the lowest average of SQTM and STM, and algorithms optimal in SQTM turns need not be the algorithm with the lowest average of SQTM and STM. Therefore the average for a given case might be from an algorithm optimal in SQTM moves, optimal in STM moves or optimal in both.
  • Of course this ranking is based off of required moves. It is not based off of the amount of time it takes to solve a case.
  • These results will change in the future if shorter algorithms are found for any of these cases.
  • Lastly, note that term "optimal average" below does not necessarily mean the average of the minimum SQTM and STM (if an algorithm has both the fewest SQTM and STM, then yes). It's an average of the SQTM and STM of one algorithm. Should one algorithm have the least SQTM but not the least STM, we do not average the shortest numbers from two different algorithms.
  • The table shows that the "worst case" is Adjacent Double Parity, and that the "easiest case" is the Checkerboard Pattern (in two opposite edges).



Algorithms Which Don't Preserve the Centers

  • These algorithms are for fixing the wing edges, but they do not preserve the centers. Many of these algorithms can be used in solving methods such as the Cage Method.

Parity Algorithms Which Don't Preserve F3L or the Colors of the Centers

  • These algorithms are least practical when it comes to use of parity algorithms, and therefore they are mentioned here for theoretical purposes only. They have fewer moves than any other OLL Parity algorithm forms.

2-Cycles

  • Although the following list of algorithms is not "OLL Parity", where dedge preservation is important, they are the briefest 2-cycle algorithms yet to be found. They do not preserve F3L or the centers.
  • These algorithms are nothing more than 2-cycle algorithms which don't preserve centers with beginning and ending outer layer turns omitted.
