Distributed.net Finds Optimal 25-Mark Golomb Ruler 265
kpearson writes "Distributed.net's 8-year-old OGR-25 distributed computing project has just proven conclusively that the predicted shortest 25-mark Golomb ruler is optimal. 'The total length of the ruler is 480, with marks at positions: 0 12 29 39 72 91 146 157 160 161 166 191 207 214 258 290 316 354 372 394 396 431 459 467 480. (This ruler may alternatively be expressed in terms of the distance between those positions, which is how dnetc displays them: 12-17-10-33-19-...).' 124,387 people participated in the project and two people found the shortest ruler, one on October 10, 2007 and the other on March 24, 2008."
What will be their next project? (Score:4, Interesting)
distributed.net used to have a very vibrant community, with several projects on-going at one time. But lately, things haven't been going so well for them. The prize funds for their RC5-72 challenge were recently yanked. And the only other project they had on-going was this OGR-25 project.
Does anyone know if they'll offer further projects in the near future? Many people I know have moved on to BOINC-based [berkeley.edu] distributed computing projects, instead of sticking with distributed.net.
can someone please tell me which #s aren't incl? (Score:2, Interesting)
So does anyone have a list of numbers that can't be measured as distances between these? I'd rather not calculate it myself.
