12 July 2019 M Queens for arm64
We released now also a M Queens app for arm64.
9 July 2019 M Queens M=27 started
The 27x27 board is the highest-order board that has been completely
enumerated. In 2016, after more than a year of computation on FPGA,
29,363,495,934,315,694 solutions were enumerated at University of Dresden.
We want ot verify this number and have to run 2.2 million workunits, which
we compute twice. On the progress bar you see 25% of it.
We'll see if we need also a year for this.
5 July 2019 M Queens for M=27
With our last run for M=24 we verified the Windows app and the validation against Linux. With our test runs we were able to confirm the amount of solutions for M=21 and M=24. So now we are ready for M=27. Some workunits are already created.
3 July 2019 Windows App for M Queens
The Windows version of the M Queens app is now available together with some workunits for M=21 to test the windows version and the validation against the Linux version.
30 June 2019 New Project M Queens
We started M Queens as new project in yoyo@home.
The M queens puzzle
is the problem of placing M chess queens on an M x M chessboard
so that no two queens threaten each other; thus, a solution requires that no two
queens share the same row, column, or diagonal.
Curently it is a test application only available for Linux64 and we are running some test workunits
for M=24. We did already M=20 and verified the results. As next step we will verfy the number of solutions
for M=27. If everything runs well we might go to find solutions for M=28, which is currently unknown.
