What is RakeSearch?

The enormous size of the diagonal Latin squares space makes it unfeasible to enumerate all its objects straightforwardly in reasonable time. So, in order to discover the structure of this space, sophisticated search methods are needed. In RakeSearch project, we implement an application that picks up separate pairs of mutually orthogonal DLSs, which allows to reconstruct full graphs of their orthogonality. You can contribute to our research by running a free program on your computer.

For account creation please use a Crunch_4Science invitation code.

Results of the first half of the January 2020!
Dear participants!

Very unusual half of winter with the air temperature between -5..+3 has passed. (But maybe a normal one if we review not last scores but last thousands of years!) The last weeks are not a time of snow, but a time of ice that formed at night from snow melted during the day. And crystals of ice from a nice photography became the basis of badge of this month! 131 participants received it and we congratulate them:

Happy New Year!
Dear participants!

On September 24, we made a report about RakeSearch project in the conference Russian Supercomputing Days'2019. Our paper about it was included in an issue of Communications in Computer and Information Science, volume 1129. Due to copyright limitations, we cannot put the full text into public access, but we place a link into the personal account page of any participant who passed the 5000 Cobblestones milestone of the total credit.

Thank you for participation!

Results of the first half of the December 2019!
Dear folks!

The first half of December of over and we can sum it up! 40139 workunits were completed and computers of 118 participants found pairs with a high degree of orthogonality. Each of them receives the "Autumn larch" badge (which was made from the nice photograph of 4h4photography). A tall tree with strong roots, hardwood and unusual for the coniferous annual dropping of needles - a good symbol of farewell to autumn and a meeting with winter!

Statistics of findings of the first half of the month:
Degree 81: 1786297
Degree 82: 424150

November 2019 totals
Dear folks!

New project productivity high record of R10 search set in November! 84297 workunits were processed and got the canonical result. In the second half of the month computers of 104 participants (that listed below) found pairs of diagonal Latin squares with a degree of orthogonality >= 86 and 39 of them, that did it for the first time in this November - got a badge!

Results of the first half of the November 2019!
Dear participants!

This November is unusually warm. Autumn does not want to give its last weeks to winter, filling them by fog and rains. And maybe the best symbol of the month like this - a moss! We are used to it and often pass by, not paying attention to moss. But it's very unusual plants! Mosses (and generally - bryophytes) is a separate and parallel branch of land plants with different from other plants' internal structure and organization of the lifecycle and maybe it is one of the first forms of life, that began to inhabit the surface of the continents, emerging from the Earth oceans. About four hundreds of millions of years ago, during Silurian and Devonian periods, lines of ancestors of the modern divisions of plants - are dispersed and the bryophyte line strategy was not the most successful - branches of vascular plants spread above the ground and bryophytes left to live in their shadow. But how much benefit they have brought to human civilization during many and many hundreds of years! We have are many reasons to say thanks to them.
In conclusion, we congratulate the next 120 participants whose computers find pairs with a degree of orthogonality >= 86 and brought to their owners the Moss badge:
