The method development competition of 2023 has officially ended! Here are the methods:

Team 5.708 @JDAW6 with JJ Method
Method description pure copy and paste:

First you Solve a 2x2x2 in the back left (if u like R U Gen ) Or in the back right (if u prefer L U gen).

Next Do EO but preserve the block in the back.

Thirdly, solve the FL pair.

Here you have to do corner permutation which is summed up nicely by Devagio

Just like EO of edges in R and U layers allows them to be solved without the intervention of F and B faces, CP of corners in R and U layers allows them to be solved without the intervention of F, B, L and D faces. What is a solved CP exactly? We do not really have to care to answer that question beyond noting that it is a permutation of the 6 corners in the R and U layers such that it is solvable using R and U; I have already done the work and you just gotta learn some rules.

1) After you solve the two corners in the bottom left, you can solve the CP by "swapping" a pair of the remaining corners. Determining which corners to swap exactly is the hard part, we'll get to that later. We'll first see how to swap them.

2) The "swapping" can be done by using one of the following 3 triggers:
a. F' U' F swaps corners in spots UFL and UFR
b. F' U F or F R’ F’ swap corners in spots UFR and UBR (edited)
c. F R F' swaps corners in spots UBL and UBR
Any or all of these moves may even be wide moves, as per the convenience of solving the DL edge of the CP-line. Also, if the corners you want to swap aren't in these locations, simply get them there using R and U moves (or their wide versions).



Now we get into the numbering system, which will be used to determine which corners to swap. For now, assume that the two corners in bottom left are already solved, and for now say we have yellow on bottom. The following bit is quite complicated, but with practice, it'll become second nature in less than an hour.

I have numbered the white-green-orange corner as 1, the white-orange-blue as 2, white-blue-red as 3 and the white-red-green as 4. The corner that is supposed to be solved in DFR is called 5, and the corner that is to be solved in DBR is called 6.

Now, imagine a thread in the cube going from locations UFL-UBL-UBR-UFR-DFR-DBR. The locations UFL, UBR and DFR are called odd places, and the locations UBL, UFR and DBR are called even places. Also, there are three couples: UFL-UBL, UBR-UFR and DFR-DBR. Trace these on a cube and you will see the obvious patterns.

Now that the naming is out of the way, we can have a look at how to identify which corners to swap to solve CP.

1) Look for corner 5. If it is in an odd location, we will "read" the thread from UFL to DBR. If corner 5 is in an even location, we will read from DBR to UFL (The meaning of reading is obvious later).

2) Now look for corner 6. It can be in 3 possible locations.
a. If corner 6 is in the couple of location of 5, do nothing.
b. If corner 6 is in another couple and the parity of its location is different from the parity of location of 5, then visualise the corners in the third couple swapped, and corner 6 swapped with the corner in the couple of corner 5.
c. If corner 6 is in another couple and the parity of its location is the same as the parity of location of 5, then visualise the third corner in the same parity location swapped with the other corner in the couple of corner 6, and corner 6 swapped with the corner in the couple of corner 5.

3) Now read the thread in the direction as dictated by rule 1, with the considerations of rule 2, ignoring 5 and 6. You will obtain some permutation of the numbers 1, 2, 3 and 4. Starting from 4, cyclically read the numbers (For eg: 3421 changes to 213).



You will have one of 6 possible sequences:

123: CP is solved

132: swap either 2-3 or 1-6 or 4-5
213: swap either 1-2 or 3-5 or 4-6 (edited)

231: swap either 1-4 or 2-5 or 3-6
312: swap either 3-4 or 1-5 or 2-6

321: swap either 3-1 or 2-4 or 5-6

You can choose any one of these swaps based on convenience of simultaneously putting the DL edge.

This is basically all you need to get started with this method given you understand the concept of EO.

Till then, here is an example.


Scramble: L2 F2 D2 B' R2 B' D2 B' U2 L2 R' B D' F2 L' D R2 F L B2

x' y' (putting solved corners in bottom left)
a. 5 is in UFR, an even position, thus we read starting from DRB
b. 6 is in DRB, also an even position. Thus we visualise UBL swapped with DFR and UBR swapped with DRB.
c. Now, skipping the couple that will now have 5 and 6 as we have visualised, we read - DRB-DRF-UBL-UFL, which after the swaps has converted to UBR-UBL-DFR-UFL, which is 2143
d. Removing 4 we have 321, i.e. we have to swap either 1-3 or 2-4 or 5-6.
e. A good way to solve CP while solving DL is to swap 5-6 as follows:
U R2 f' u' F (the final u' is a wide move to facilitate the next step, which will be U R' u' R' u2)
Here, the U R2 was to set up 5 and 6 to swappable positions, and the trigger used was a variation of F' U' F.

Then finish off the cube 2 GEN RU or LU depending on what u chose.

Vote for your winners here:

You cannot vote for a winner of FMC as that is not exactly controversial as you just pick the one with the lowest movecount which is Triceratops method from @DoAnKhang . Congrats for triceratops Method for winning fmc!

Are you seriously accepting the zapper method as a valid submission? There is literally no difference between it and Petrus. And this is not just the common criticism of a method being Petrus but worse, the method is literally just the exact steps of the Petrus method.
 
Voted.

It was a difficult decision for 2H between two of them. There was an interesting idea in each. I also see some improvements that could be made to the methods that may have changed the vote if implemented.

For OH, none really seem that great for OH. Either difficult mid-solve recognition or large alg sets that would need to be optimized for OH.
 
The votes have been locked in and these are our results (22 total votes):

Winner of OH:
PBCS

Winner of 2H:
PBCS

Winner of Most Original:
2NAKe

Winner of FMC:
Triceratops

I added all of the Method Development Competition methods to the Method Library. This includes all four Method Development Competitions.

Hey Athefre I think there are a few mistakes in your description of my method on the Method Library.
Here is your description of the Triceratops method on the Method Library:

Here is how it suppose to be:
  • Step 1: Solve the dL 1x2x3.
  • Step 2: Solve the three dR edges.
  • Step 3: Orient all remaining edges while solving the DF and DB edges
  • Step 4: Orient the remaining corners while solving the DBR corner or both DR corners
  • Step 5: Finish with TTLL or PLL

Thank you. I just corrected it. Must have been a copy and paste remnant. Also corrected Step 3's "M layer edges" to "M layer centers".
 
There is a mistake in mine too, it says solve the dFL pair it also has to say while preserving EO And then in the last step in ends with RU gen as EO and CP is done
Honestly I didn't completely understand the method description. I read over it a bunch of times and thought I had it. Would you mind writing the method out in steps? Step 1, Step 2, etc.
