(Last updated: November 15, 2024)
Ever since y-cruncher was unlocked in 2010 to allow anybody to set a record, it's become somewhat of a competition to stay atop the board. And because of this, some rules need to be set to keep things fair and to ensure an acceptable level of confidence that the computations are correct.
If you wish to set a record, you must:
For y-cruncher v0.7.8, turning on disk I/O checksums is not necessary to establish a record. But it is recommended anyway to increase the chances of detecting errors before the end of the computation.
*The validation files are protected with a checksum to prevent tampering/cheating. People have tried to cheat before - which is why we can't have nice things.
Exceptions for Pi:
Pi is special since it is the constant and everybody pushes to the extreme limit to compute it. Therefore there is a special method to verify Pi that doesn't require a second computation.
Note that for anyone attempting to set a Pi world record: Should the attempt succeed, I kindly ask that you make yourself sufficiently available for external requests to access or download the digits in its entirety (at least until it is broken again by someone else). Pi is popular enough that people do actually want to see the digits.
To compute and verify Pi using only one computation, you must:
#1 and #2 are needed because only the built-in swap mode implementations have the final verification step to ensure that errors are propagated to the last digits.
#3 is needed because you need the hexadecimal digits to compare with the BBP computation.
The rest are self-explanatory.
The BBP formula computation (#6) is very fast compared to the main computation. If you're attempting a Pi world record and you've been in contact with me the whole time, I will probably be doing this step for you on my own hardware as you near the end of your computation. So I will probably have the hexadecimal digits waiting for you at the end of the main computation.
This BBP formula method can theoretically be extended to other constants as well. But none of them have the additional verification steps to make this valid.
Custom Formulas:
The rule is that in order to claim a world record, you must do the computation using two computationally independent methods. This (unwritten) rule has existed for many decades and has long preceeded y-cruncher. Exceptions can be made only if there is an alternate method of verification.
"Computationally independent" means that any errors (hardware or software) that occur in either computation will (with extreme probability) cause the computations to either fail, or have mismatching digits.
For example, the following two methods to compute sqrt(Pi) are dependent:
If there is a bug in the implementation of the square root function, both computations will yield the same (incorrect) results. It doesn't matter if Pi itself is done using different algorithms*.
Up until y-cruncher v0.7.6, all the algorithms that it has provided for the same constant are indeed independent. This was intentional so that anybody can pick any two algorithms and run a compute+verify pair - no questions asked. But this changes in y-cruncher v0.7.7 due to the custom formula feature. Now you can enter your own formulas. And thus there is no longer any protection against using two formulas that are computationally dependent.
The line between whether a pair of formulas is sufficiently independent is not well-defined. So I will be making a judgement call on these. And I will reject world records done using a pair of formulas if I deem them to be too similar or not computationally independent.
The file "Custom Formulas/#README.txt" will tell you all the dependent sets of formulas that cannot be used as a compute+verify pair.
*The same argument can be made about y-cruncher's radix conversion since all computations and all formulas will go through the same radix conversion code. The "Output Verify" option enables a series of verification steps for both the radix conversion and the output of digits to disk. This ensures that there is no single point of failure (hardware or software) that can lead to incorrect digits being undetected.
What Constants are Tracked:
Since there's an unlimited number of things that can be computed, I will only track a small subset of them.
The official list is (in approximate order of popularity and mathematical importance):

As of this writing, all of these records are currently held by y-cruncher. But of course this can and will eventually change in the future.
*Gamma(1/5) is a new constant. Currently (as of v0.8.5) there is only one fast formula that y-cruncher can run with nothing else to verify. Verification of Gerd Lamprecht's computation of 3 billion digits was done with a beta/prototype implementation of a different algorithm that will hopefully land in v0.8.6.
Blue: Current World Record
Green: Former World Record
Red: Unverified computation.*
*To protect against computation errors from software bugs and/or hardware instability, a computation must be verified before it counts as a world record.
This is usually done by repeating the computation using a different and independent formula.

*This first world record for Pi was run entirely by Shigeru Kondo, but with a lot of support from me (Alexander Yee) to get it done. There was also a lot of back-and-forth testing between the two of us to stabilize the y-cruncher software before he could actually run the main computation.
After this first record, we had more or less learned what was needed. So from there on, all the later records were mostly on his own.
This is a list of other notably large computations. They are notable either because they are long running and either came close to a record, or are for less popular constants that nobody tracks.
In order to keep this table from getting out of hand, starting October 19, 2018, I will only officially be tracking world records for:
Everything else will be on a case-by-case basis. And I won't be accepting anything new unless it is a very expensive computation which I'll hand-wavingly define as:
Blue: Current World Record
Green: Former world record or not a world record.
Red: Unverified computation or not a world record.
