Dear participants!

A new search started in the project on September 27 - "Joint search of ODLS9 with Gerasim project". Earlier we performed a full search over the space of row-permutational diagonal Latin squares of order 9, but in this search (that we perform with Gerasim@Home project) we try to find all orthogonal diagonal Latin squares of order 9! At the first glance, the goal is unreachable, but the new search uses an heuristics that allowed to reduce the amount of computations.

In this thread we will post news about the new search.

News # G9.1: Badges!

Of course we plan to make badges. The first of them is related to Kursk - the city of South-West State University, Russia, where works the scientist of the Gerasim@Home project Eduard Vatutin.
Many people know Kursk by the biggest tank battle in history, but the symbol of Kurk is... a nightingale! And it's a symbol of search started in October (and last days of September) in our project!
(Badge was made from pretty photograph by wal_172619 from Pixabay).

Try to find records of the song of Kursk's nightingale!

Hello Jürgen!
When will there be a Linux-application ?

Jürgen

This is currently unknown. It is possible that it will only exist under Windows.

Are you planning monthly badges (similar to the previous badging plan) for this "sub-project"?

Hello Jürgen!

Jürgen

This is currently unknown. It is possible that it will only exist under Windows.

I have checked your app and found that it was written in Delphi. I tried to google for Linux Delphi compilers, and found this: https://stackoverflow.com/questions/10109234/delphi-cross-compiler-for-linux. One of them is Lazarus, it looks promising. I also found that it can be built with LLVM support. LLVM is used as a backend by clang compiler, so compiled code should be well optimized. Please take a look on this, I am also waiting for Linux app.

Sorry for long answer. As is the first search in space for squares of the 9th order, the badges given for finding orthogonal squares!

Hi,

now I got the gerasim project runnung under linux. I've installed it via wine (a windows-api-emulator).

ca. 850 WUs are now completed successful.

Hi folks!
The first badge of joint search of ODLS9 with Gerasim project - are granted and it was received by 323 participants!
Our warm congratulations to:
......

Can I still earn the badge ?
Will it be awarded immediately after finding something ?

Where can I see found pairs?

The link on my account page "Results with ODLS pairs" shows, that the list is from
"The last result of entire list as a whole received at: 2019.06.16 22:14:51"
(I've joined the project in Jun 2020)

ca. 850 WUs are now completed successful.

Thank you for participation! :)

Usually, badges awarded near half of month and in first days of next month, when we summarize results.

Where can I see found pairs?

Files of results of this search much less visual than first search in our project. We think about methods of results publishing.

The link on my account page "Results with ODLS pairs" shows, that the list is from
"The last result of entire list as a whole received at: 2019.06.16 22:14:51"
(I've joined the project in Jun 2020)

Yes, it's normal. For example on my page:

2019 June
R9_022694121 R9_022975153 R9_023033826 R9_023209351 R9_023209350
Total results: 207
Your last result received at: 2019.06.10 13:20:51 | The last result of entire list as a whole received at: 2019.06.16 22:14:51

Phrase about "entire list" related to whole set of results. Search ended in 2019 and this row report about it. :)

Thanks for the info.

To have a check about foundings, I'm thinking about to write a cron job that pareses the boinc-slots to check, if a process have found a pair.

My question: where is a possible founding logged (which files) ?
What is written to the file (example), so I can scan for it?

The most realistic way - take a bunch of tasks, disable network interaction, wait while tasks completed and copy results files from project directory. But in results stored information about squares, that have ODLS, but not pairs.
