| 00:00.43 | dtidrow | haven't had a problem with that here, and the lib we load sucks in a lot of .so's |
| 00:02.20 | dtidrow | you're not trying to pass in the full name of the lib, are you? |
| 00:03.20 | dtidrow | iiuc, System.loadLibrary() expands the name given to it, eg. 'vis' expands to libvis.so |
| 00:03.55 | dtidrow | at least on Linux - all bets are off on OSX ;-) |
| 00:03.58 | brlcad | I'll dig to make sure, but I'm pretty sure it's just the short name |
| 00:04.25 | dtidrow | OSX has some weird packaging schemes |
| 00:04.31 | brlcad | like I said, it works just fine if the .so is resolved, it's only when it's not |
| 00:05.02 | dtidrow | resolved meaning it can find it in the LD_LIBRARY_PATH? |
| 00:05.32 | brlcad | no, meaning that it doesn't have to -- all symbols in the .so are resolved (none undefined if you do an nm) |
| 00:05.40 | dtidrow | ah |
| 00:05.47 | dtidrow | odd |
| 00:07.00 | brlcad | yeah, it's just: System.loadLibrary ("rtserver"); |
| 00:07.09 | brlcad | we have a librtserver in brl-cad |
| 00:07.14 | brlcad | pretty straightforward |
| 00:07.35 | dtidrow | librtserver.so? |
| 00:07.49 | brlcad | on non-mac, yes :) |
| 00:08.15 | dtidrow | it works on non-macs? |
| 00:08.23 | dtidrow | or n ot at all? |
| 00:08.29 | brlcad | iirc, no -- not at all |
| 00:09.36 | dtidrow | gotta be an libpath issue, then - any chance that LD_LIBRARY_PATH was getting reset/changed before java ran? |
| 00:09.53 | dtidrow | like in a script, perhaps? |
| 00:10.02 | dtidrow | jsut brainstorming here... |
| 00:10.36 | brlcad | the ld path is set, it's set to a mass of paths that are otherwise required for other javanessy things it needs (and one of the paths includes the dir that has the .so's in question) |
| 00:11.07 | brlcad | otherwise even System.loadLibrary ("rtserver"); wouldn't work on the fully resolved library |
| 00:11.13 | dtidrow | very odd, then - it _ought_ to work |
| 00:11.44 | dtidrow | and 'ldd' finds all the deps? |
| 00:12.14 | brlcad | yeah, it does |
| 00:12.50 | dtidrow | makes no sense at all then |
| 00:15.11 | dtidrow | anyway, gotta head home - 'nite all... |

| 21:53.02 | poolio | brlcad: I remember in the past you told me not to modify the rt_i, (when it was clamping the bounding box) but if I need to shoot the same grid for each shape, won't I have to modify the variables inside of the application? |
| 21:53.16 | *** join/#brlcad Twingy (n=justin@74.92.144.217) | |
| 21:53.48 | poolio | it looks like I missed that and that could have been why it wasn't working well. the fitness seems pretty arbitrary |
| 21:55.18 | poolio | well actually it was fine before, but that was because they were normalized to the z-depth, so scale was invariant along the z-axis, but I changed it assuming z-depth would be constant and that's where I ran into some problems. So I'm wondering if there's a way to clamp that value basically? |
| 21:57.09 | poolio | although it does eliminate a dimension at the cost of having a distorted object |
| 22:16.59 | brlcad | poolio: there is a_ray_length that will specify at what length the ray should terminate |
| 22:17.04 | brlcad | in the rti |
| 22:17.05 | poolio | brlcad: alright thanks |
| 22:17.08 | poolio | I actually went back to scaling |
| 22:17.11 | poolio | results seem slightly better |
| 22:17.17 | poolio | I now have the fixed-depth crossover working |
| 22:17.17 | brlcad | similar to a_onehit |
| 22:17.26 | poolio | yeah alright, thanks |
| 22:17.31 | poolio | the issue those is if it's offset, I'm screwed |
| 22:17.42 | poolio | Oh wait nevermind..I control where the ray is shot from |
| 22:17.44 | poolio | thanks :) |
| 22:18.54 | brlcad | how do you figure "results seem slightly better" ... |
| 22:19.23 | brlcad | it simply introduces more variability, so it won't necessarily get stuck on a bad answer .. that doesn't mean it's better though |
| 22:19.51 | poolio | slightly better with the crossover that makes sense (for now) |
| 22:20.03 | poolio | and something is up with fitness, give me a minute and Ill have some data to show you |
| 22:20.14 | brlcad | it shouldn't have anything to do with crossover |
| 22:20.23 | poolio | the results shouldn't? |
| 22:21.13 | brlcad | using a scaled size in your fitness function shouldn't have anything to do with crossover |
| 22:21.25 | brlcad | so yeah, the results shouldn't |
| 22:21.36 | poolio | Correct, yes. |
| 22:21.40 | brlcad | if they do, I'd think something else is suspect |
| 22:21.51 | poolio | The issue was that I had undid the scaling, taken the final difference, and divided that by the # of rays |
| 22:22.02 | poolio | the issue was that the rays fired at different lengths so I was getting odd answers |
| 22:22.31 | brlcad | yes, that's a problem confined to the fitness function :) |
| 22:22.56 | brlcad | scaling might make the math work out easier, but I don't think it's right |
| 22:23.18 | poolio | well, I was moving the scaling out, because I was scaling each bit |
| 22:23.20 | poolio | so I had like |
| 22:23.35 | poolio | <PROTECTED> |
| 22:23.51 | poolio | so i was moving it so I stored the non-scaled rays, and then when I had calculated the comparison, then dividing that |
| 22:23.53 | brlcad | take the union of both bounding boxes, that's your absolute length, then compare % matching |
| 22:24.11 | poolio | I could do that too |
| 22:27.01 | poolio | alright I'm doing a larger run and then I'll show you the results. Hopefully it will be better :P |
| 22:30.26 | poolio | brlcad: yeah something is wrong here. fitness is ... decreasing |
| 22:35.45 | brlcad | hehe |
| 22:37.07 | poolio | what a fugly graph |
| 22:38.31 | poolio | brlcad: http://poolio.org/index.php?q=node/8 |
| 22:40.19 | poolio | brlcad: although wait, something has to be wrong with the fitness function. Look at the best individuals...they're different ... |
| 22:40.47 | poolio | Oh that was the other thing, can I raytrace those objects using 'rt' with a specified bounding box instead of an auto-generated one? |
| 22:44.16 | brlcad | what are the three lines in the graph? |
| 22:44.33 | poolio | wrost/average/best individuals for each generation |
| 22:44.38 | poolio | read the description :P |
| 22:45.29 | brlcad | yeah ... that's not at all what it should look like :) |
| 22:45.35 | poolio | yeah I know |
| 22:45.40 | poolio | I'm guessing my fitness function is broken |
| 22:45.47 | poolio | juding from the output of the visual and the output of the graph |
| 22:46.18 | poolio | It was the first thing I did and I trusted it was right but maybe not |
| 22:47.04 | poolio | the questionable code resides in compare_hit() in fitness.c |
| 22:47.12 | brlcad | you can almost ignore the visual for the time being .. average and best won't likely get that close that fast |
| 22:47.50 | brlcad | also, did you implement the "bring best N forward" yet? |
| 22:47.56 | poolio | no |
| 22:47.59 | brlcad | if so, that 70% shouldn't have disappeartd |
| 22:48.00 | poolio | I can whip that up in a minute though |
| 22:48.01 | brlcad | ahh, k |
| 22:48.30 | brlcad | i think you're right, though -- fitness function seems wrong |
| 22:48.51 | brlcad | or some twisted crossover bug is killing off your population |
| 22:49.01 | poolio | I have a family dinner to get to but I'll be back around 9. I'm guessing the isuse has to do with the compare_hit routine I've been trusting |
| 22:49.16 | poolio | I might take that out and run some test cases to make sure it's working right |
| 22:50.00 | brlcad | have a good dinner ;) |
| 22:50.17 | poolio | thanks for the help, hopefully I'll have something good to show you soon |
| 22:52.06 | poolio | :\ |

| 22:52.31 | brlcad | once it starts working, I think it'll be a lot more encouraging ;) |
| 22:52.42 | brlcad | yeah, timeline is the only crunch |
| 22:52.51 | poolio | I _need_ something working |
| 22:53.05 | poolio | Not just for you to show, but also to know I didn't waste away my summer on a broken hunk of code |
| 22:53.16 | brlcad | likewise |
| 22:53.48 | poolio | wow. pretty embarassing how little code there is too |
| 22:53.49 | brlcad | being able to demo your program to dozens of people you've never met ... |
| 22:53.50 | poolio | <2k |
| 22:53.54 | brlcad | that control lots of money :) |
| 22:54.10 | poolio | even if it only works on simple test cases? |
| 22:54.15 | brlcad | yes |
| 22:54.27 | brlcad | the technical aspects are pretty deep |
| 22:54.48 | poolio | but the code and implementation isn't that difficult |
| 22:54.49 | brlcad | probably a little more deep that you know yet, which is part why it's been a lil tricky to implement aside from the coding issues |
| 22:54.56 | poolio | If you had 5 days to spare you could have done it by now |
| 22:55.08 | brlcad | i don't have 5 days to spare :) |
| 22:55.14 | brlcad | contrary to the time I spend on IRC |
| 22:55.32 | poolio | just don't sleep. you'll do fine. |
| 22:55.56 | poolio | your time is also much more valuable |
| 22:56.10 | poolio | but seriously, if you took the time you've spent helping me out / trying to get me the job, it could've been done by now |
| 22:56.22 | poolio | (i'm just slightly pessimistic :)) |
| 22:58.01 | brlcad | getting good people is often way more important than getting the work done |
| 22:58.19 | brlcad | if the work was the #1 priority in your case, you wouldn't be working on this pariticular project |
| 22:58.35 | brlcad | it would have been one of the other tasks .. or worse ;) |
