  • 03-06-2018: RakeSearch, Next 9 of graph types

    Dear folks!

    The next set of graph types was published on preliminary results page! It consist of 9 samples:

    [R9_000046266/01] - consist of 56 verticles and 360 edges. Verticles of this graph broken on core and two branches. Inside core we can see group of 16 verticles, located in "central circle", outer ring of another 16 verticles, and 4 verticles which a base for two branches. Each of verticle from "circle" linked with all 16 verticles from outer ring and 4 verticles from branch base but no any links exist between them! In consequence, each of 16 verticles of outer ring linked with all verticles in "central circle". Verticles in branches base - also.


    [R9_000046266/02] - 78 verticles and 448 edges forms "arm" and "body" which are build from belts of verticles. Verticles in each belt linked with verticles in near belts.


    [R9_000046269/02] - 32 verticles and 256 edges. Each verticle from rim connected to all vericles in center and each verticle in center connected with all "rim verticles". And no any links exist between verticles inside center.


    [R9_000046269/04] - 16 verticles and 28 edges. "Ray-like" figure from two central verticles and three "rays" outgoing from them.


    [R9_000046269/05] - 18 verticles and 40 edges. "Arm", "body", "horns". :) Unusual figure!


    [R9_000047793/01] - 104 verticles and 644 edges. Interesting combination of two "belts" into "core", "rays" and "horns"! What is it? :)


    [R9_000047793/02] - 80 verticles and 688 edges. Big insect?


    [R9_000047796/02] - 28 verticles and 96 edges. Another challenge for naming!


    [R9_000047796/04] - 16 verticles and 64 edges. Verticles in "central belt" linked with all verticles in left and right "belts".



  • 02-06-2018: SRBase, base R579 proven

    On 24th of May, JD2K, a member of the team Gridcoin found the last prime for base R579.
    The prime 104*579^222402-1 has 614428 digits and entered the TOP5000 in Chris Caldwell's The Largest Known Primes Database.

    Good job!



  • 02-06-2018: RakeSearch, Saturday graphs!

    Dear crunchers!

    On preliminary results page we publish a next 5 types of graphs discovered in RakeSearch project:

    [R9_000043841/01] - 8 verticles and 9 edges. Simple and symmetrical graph!


    [R9_000044083/02] - 212 verticles and 1104 edges. Fourth by number of squares on today. We see a many "petals" - they corresponds a set of squares, each of them is orthogonal to 2 other squares, "located" in center of "flower".


    [R9_000044085/03] - 56 verticles and 400 edges. Flower in a pot?


    [R9_000044623/01] - 38 verticles and 106 edges. Can any to invent a name for this figure?


    [R9_000045135/01] - 37 verticles and 97 edges. Crab? Fish? Flower? Alive? Not?


    Thank you for attention to project and donation of CPU time!

  • 27-05-2018: RakeSearch, Sunday graphs!

    Dear participants!

    On preliminary results page a new 5 types of graphs, discovered in RakeSearch project, were published.
    [R9_000042319/01] - consist from 28 verticles and 79 edges and near to figure with radial symmetry.


    [R9_000042871/02] - drafted by 68 verticles and 146 edges. A fish from seabed?


    [R9_000043553/02] - crayfish from 28 verticles and 80 edges?


    [R9_000043575/02] - looks like chrysanthemums on stems and this graph is significantly larger than previouses in group - 132 verticles and 320 edges forms it!


    [R9_000043575/03] - a relatively simple graph, only 14 verticles and 27 edges. Stops and routes of urban transport? :)


    Of course, no any sense in this figures exists and "fishes, flowers and satellites" - just for fun (it's a weekend pictures!). And using another method of graphs layouting, we can get absolutely other visible form for it. But human mind, targeted on recognition of known objects in lines and spots - will see still some figure.

    And we congratulate a Daniel from BOINC@Poland (or [B@P] Daniel) with the first place by total credit!

  • 19-05-2018: RakeSearch, Weekend news, 5 new types of graphs discovered!

    Dear folks!

    We present the next 5 types of graphs, discovered in RakeSearch project.

    The first one [R9_000040159/01] looks like a flower. Many squares of this set are orthogonal to the 2 squares, placed in the center of the graph, and during the drawing graph edges formed a "petal figure". 32 verticles and 62 edges are necessary for the growth of this flower. :)


    The second one [R9_000040275/01] - is big, second by size in entire set of graphs, that found in project today. 61824 verticles and 374064 edges construct a net with several "centers of gravity" linked by bunches of edges. Also we can see animation (8.3 Mb) with filling of this graph.


    The third one [R9_000040835/01] - comprises from 154 verticles and 1263 edges (5th by size on today!) emerging to ... a jungle flower?


    The forth one [R9_000040839/02] brings us to mind the animals of ancient life of Earth. Only 16 verticles and 34 edges form it.


    The fifth one [R9_000041622/02] looks like significantly more modern object! Satellite? :) 24 squares fastened by 84 relationships of orthogonality are needed for build this "space telescope".


    And in the end, we congratulate all participants of the 9th BOINC Pentathlon with finishing this challenge! Winners, who crunched millions of tasks and teams that completed at least one workunit! Distributed computing is remarkable and extraordinary feature of our time. And we hope that now we see only the first leaves of it.
