Dear folks!

Two days ago the project reached a milestone of 95% of completion. As part of the current search, it remains to process about 1100 000 workunits. In the next few days, we plan to generate one or several bunches of workunits for new search - in space of diagonal Latin squares of rank 10. Initially, tasks only under Linux x86-64 platform will be available, if their processing is successful, the application for Windows will be released.
A few words about the new search. We expect that an typical task will process more squares for the same time (on average). In the application for a new search, we implement some optimizations and it will be significantly faster than default application for search in space of rank 9. Another interesting thing - the search space, itself. We increase a square rank by only one stage - from 9 to 10. Currently, for workunit names we use a format R9_<8 digits> (R9_022248939 for example) and first digit from tuple - always 0. But for the naming of workunits for a new search, if we try to count all of them, we must use a format like _0000000000000001! (We don't know the number of workunits for full search in space of rank 10 precisely, but rough estimate - about 160 millions of millions of workunits). The current search comprises 23 000 000 workunits, but the full search in rank 10 space targets about 7 000 000 searches of rank 9! Of course, we cannot perform a search like this. Even with new Ryzens. :)
Also, today we do not know whether or not "permutational" orthogonal diagonal Latin squares of rank 10 exist.
For the reasons listed below, we plan to perform a search over a tiny part of entire search space - may be 1 million of workunits, may be larger, but we don't want to run an endless search without any results, because many other interesting and useful projects exist.

Thank you for attention and participation!

1.1 million or 11 million workunits left?

Hello Jaari!

1.1 million or 11 million workunits left?

1.1 million workunits.

After testing under under Linux x86-64, is there any possibility of the app being recompiled for 64-bit ARM linux as well as Windows?

Do we need to remove Daniel's optimized app in order for these to run properly?

Yes, otherwise BOINC will not download new app. You will have to remove app_info.xml and restart BOINC. When you will do this, BOINC will also download current official app, if you will have some WUs for it.

Before you do this, make sure you finish all downloaded and started WUs, or abort them. Optimized app uses a bit different checkpoint file format, which is not compatible with official app. It will not work properly if it will load such file.
You can keep WUs which are not started.

We will try to make a new application, but not its version, so that participants do not have to give up the optimized one (for current search). We work about it.

So RakeSearch's work in the Latin Square space does have a distinct goal from what ODLK and ODLK1 and Gerasim are undertaking.

We have had heated debates in Gridcoin chat about whether to attempt to whitelist this project, and bring our team into help out, but some of our important members are convinced your project is not doing significantly different research other than working on 9x9 instead of 10x10.

Can you point me to a paper describing the difference in the mathematics between here and those other projects?

Would you all like to be on the Gridcoin whitelist?

Will it be a separate sub-project, for example like PrimeGrid's, so each one has their own credit level, badges etc ?

Over 300 v10 tasks completed w/o error. There is no more work atm for the new app.

Edit:
Evidently the refreshes of a post submission worked but I could never see them. :(

Hi everyone! For rank 9, we are able to check the full space (that is almost finished, 96%). For rank 10, the full check is impossible, so we will start from special subsets. It is an open question whether permutational pairs exist for rank 10. So if we find some, it will be already a novel result.

In Gerasim@home, they do not aim for ODLS graphs, although receive them as a lateral result. We will use their statistics (rate of pairs discovery) to understand if RakeSearch algorithm is useful to complement research of the space of rank 10. We are in contact with the scientific leader of Gerasim@home, and he will help to direct the research. In ODLK*, they obtain canonical forms, which is a different research.

You can see (not paper, but slides) about mathematic principles of search by this link.

We don't know how long the next search will be. It is possible that this issue may be postponed by some time.

We add an application for Windows x86-64 and next 1000 workunits. (For rank 10).

Thank you for the feedback!

Is there a way to just get the new 10 work units. I have deleted the app_config file but I am still getting the old files as well as the new ones and the old ones take two or three times the time to complete.

Does the new application have a new app_name ?

In RakeSearch preferences you can choose which apps you want to run. By default all apps are enabled.

I have completed about 700 of the new rank 10 WUs without issue on my various Threadripper and Intel systems under Windows 10. Have any ODLS pairs been found yet in the rank 10 search?

---

I have now completed ~5600 of the rank 10 tasks, with another ~800 pending validation. Any indication yet if this new search will produce any favorable results?

Thank you for reports! Now completed ~11000 of workunits and no pairs with ODLS found. For rank 9 on average, ratio is ~1/270.
