Dear participants!
We start a new joint search with [email protected] project: calculation of spectrum of characteristics of diagonal Latin squares. As mathematical objects, DLS have various numerical characteristics. The spectrum of a characteristic is the range of values it can take. You can read about the scientific background of this new search in presentations of Eduard Vatutin: About Spectra of DLS of small orders and about Spectra of DLS of high orders and volunteer computing grid.

To help increase interest in the project, I am creating a new badge based on fields counts, and tuned especially towards subfield 7. If this works well, I will also create separate badges for the other subfields.
I already put the hooks in to keep tract of the field counts for sf7. Now it's just a matter of creating the badge images, etc. Hopefully that should be done in the next several days.
Happy crunching!

I'm pleased to announce that we have reached a new milestone: more than 90,000 mined programs for OEIS integer sequences. Thank you all for your contributions to the LODA project!
Since our last major milestone in late of May, we have made various improvements to our mining tool, our infrastructure and project websites. This includes among others:
Our next target milestone is to reach 100,000 programs. We plan to improve the quality of the mined programs by including additional data sources and extend the configuration of the miners to improve the mining rates. Reducing errors stays one of our top priorities. We rely on your support for reaching our next milestone and highly appreciate your contributions!
Cheers,
The LODA Team

There will be an update for all 64bit llr apps shortly. Its based on the apps which PG is using and will benefit from the Gerbicz check. The speed is a little bit slower. Its based on llr3.8.23 with gwnum 30.4

has 575760702 orthogonal mates which puts it on the 13th place of the rating between square with 357535322 orthogonal mates and square with 780235212 mates. And it is interesting!

We are scheduling project outages from June 10, 2022 to June 12, 2022.
These will be temporary access issues.
Sometimes these interruptions may last a few hours at most.
The downtime is related to upgrades (frequent problems with hard drives and storage on the iThena.Measurements platform).

I'll be losing my "computer room" in my basement this week while water seepage mitigation is done. After that, the house goes on the market as I'll be relocating to a state with nicer climate with fewer corrupt politicians and lower taxes. The result is that the Collatz project will be down for some time. Please set your machines to get no new work because you likely won't be able to return the work before it times out. The work starts Wednesday so I have to have everything cleared out prior to that so it may be Monday or Tuesday when it gets shut down. Once I move, I don't know how reliable the broadband will be, but I'm hoping that since it will be fiber and not cable TV based, it will be decent. It should be faster and less expensive, but I can't predict when the Collatz project will be back online at this time.

Google has changed something where the mail system doesnt work anymore. I have tried another new mail address from another provider but was also not working.
Iam using now the mail address where the project has started in 2014. The testing was successful. If you have any problems let me know.

Dear all,
with your help, we have processed 15 targets already! It is a huge computational work, the results of which are being processed by our team and colleagues. We are working on two papers which will be available to the public as early as possible. We also continue computations for next targets. During March, April and May, project's performance was fluctuating around 250 Teraflops. We took this advantage to prioritize SARS-CoV-2 targets on top of the other research. At the end of spring 2022, we are 6426 active participants with 4493 computers.
With best wishes,
Natalia and the team of [email protected]

We have reached our first milestone: 80,000 programs! Thanks a lot for your contributions. This is amazing and helps us a lot to move the project forward.
Thank you also for your great feedback in the forum and on Slack. We try to fix all issues that you encounter. We also plan to work on two feature requests: milestone badges and checkpoints. For the milestone badges, if you have any suggestions for images that we can use, please post them in this thread: https://boinc.loda-lang.org/loda/forum_thread.php?id=25
Looking ahead, our long-term goal is to find programs for all of the 350k integer sequences at OEIS. So please keep on mining -- we highly appreciate your contributions. Thank you!!!
The LODA team
