Re: Harmonious Trees Meldefrist und Laufzeit?

[P3D]Emploi, thanks for your feedback. Yes, some workunit may have very long runtime. That is what we can see. Signal 11 means error in memory access in general. I am not sure yet why this error appears. I used to ran the same code on my laptop for 3 months, usually 5 days with no stop (the whole wo...

Re: Harmonious Trees Meldefrist und Laufzeit?

First, I don't speak German. I can only hope that Google didn't fail me. The application of Harmonious Tree can be proved to have no infinite loop. You can also see that it progresses by checking out checkpoint file. However, runtime may vary a lot between workunits, and this is due to the nature of...

Re: [sub-project] Perfect cuboid

Another thought: you can try to ask the academia to see if it is previously unknown. Ask guys in math dept. in the nearest university, or email to experts. Do not act like a crackpot, crackpots are usually ignored. You may find interesting and useful references. If I remember well, the book "Unsolve...

Re: [sub-project] Perfect cuboid

Hi x3mEn, I've followed all your proofs and they seem to be correct to me. I have to admit that if this works out, it will be a good subproject. Personally I have always been also interested in perfect cuboid and had done some simple (really really simple) research on it. I am not a real mathematici...

Re: Proposition of new sub-project: Graceful Tree Verificati

Hi fwjmath, over the next months I'm trying to convert your gtvb.cpp into a proper BOINC executable. Could you please send me some sample input and output files, your compiler commands (for linking and building) and your functions to validate the results? This is no official acceptance as a subproj...

Re: Proposition of new sub-project: Graceful Tree Verificati

I would be willing to crunch this as a Yoyo subproject subject to two conditions: Checkpointing in accordance with the interval set for the BOINC client, and Credit award on a rational scale consistent with other subprojects. For checkpointing, the application has a built-in checkpoint according to...

Re: Proposition of new sub-project: Graceful Tree Verificati

fwjmath, This seems to be very similar to a "Golomb Ruler" (a.k.a dnet's OGR ) but in a 2 dimensional arrangement and using sequential numbering instead of unique numbering. would that be reasonably accurate description? also are you able to guess an estimate to the expected runtime for the entire ...

Re: Proposition of new sub-project: Graceful Tree Verificati

I have put my code on the project site:

It may be difficult to read, as I was lazy to put comments when writing it......

Re: Proposition of new sub-project: Graceful Tree Verificati

Hi, for 'making it BOINC', a text-based client with an input- and an output-file would be the best thing to start with. From your description I assume the program has a GUI at the moment. What programming language is it written in? In order to be able to use your software with BOINC, you also need ...

Proposition of new sub-project: Graceful Tree Verification

Hi all, I would like to propose something as a sub-project to yoyo@home. It is called Graceful Tree Verification, a manual volunteer computing project that aims to verify a notorious open problem (graceful tree conjecture) in graph theory. This is its homepage: http://www.eleves.ens.fr/home/wfang/gt...
