There are 2 new sub-projects at Yoyo@Home ...

Quote
Nontrivial Collatz Cycle wants to prove that there are no Collatz Cycles with length < 17*10^9 other than 1 - 4 - 2.
Therefore it searches for Path Records with start numbers up to 10^20.

Quote
Perfect Cuboid aims to find Perfect Cuboid or prove that if it exists, his space diagonal must be greater than 2^63.
During the moving up we also will find almost perfect cuboids: Edge and Face cuboids (completely) and some kinds of cuboids in complex numbers (Perfect Complex, Imaginary and Twilight).

Some news from Yoyo@home ...

Quote
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.
