2011-07-07T07:15:12 yeah, well its a bug, you should nat have seen it, but i was slow to stop the recording :D 2011-07-07T07:15:27 and why does it sometimes walk along the outline when it should have turned to the food 2011-07-07T07:16:09 yeah, it doesnt find the shortest path, the exit condition from the outline is not very sophisticated 2011-07-07T07:16:30 strange :P 2011-07-07T07:16:51 i wanted to do this: find the paths that you just seen, and then do the same the other way around, that is, from food to ant, and merge the 2 paths 2011-07-07T07:17:17 id get a more optimal paths, but i stopped working on it, and started a* instead 2011-07-07T07:17:44 i just wanted to document the results, but i wont be pursuing this idea 2011-07-07T07:18:36 a* has the strong advantage of being optimal and not depending on precalculated data 2011-07-07T07:18:56 well, i dont use optimal a* :) 2011-07-07T07:19:06 i use quite a strong heiristic though 2011-07-07T07:19:25 and it is simple enough to let it run over a few hundred squares 2011-07-07T07:19:35 the advantage of a full graph searching is that you always get a PATH, that is, always find your targetr 2011-07-07T07:19:54 and a* doesn't? 2011-07-07T07:20:06 no no, i mean exactly a* 2011-07-07T07:20:22 a* graph searching ok 2011-07-07T07:20:28 its robust, you can hardly destroy this ability of its 2011-07-07T07:20:48 (this sounds very un-english) 2011-07-07T07:20:57 the ability if her/his 2011-07-07T07:21:04 the ability of her=his 2011-07-07T07:21:07 but, its? 2011-07-07T07:21:31 antimatroid: how does this sound? 2011-07-07T07:21:38 mcstar: one of my problems is that if i don't want to track collisions other than this turn, then it's faster the "backtrack" the first move needed if i search from the targets to the sources 2011-07-07T07:22:02 because then i only need to find an adjacent square to the found source with g 1 less 2011-07-07T07:22:56 ah, you dont need the full backtrack 2011-07-07T07:22:59 clever 2011-07-07T07:23:23 problem with that is my a* heuristic if i have 100's if not 1000's of ants 2011-07-07T07:23:24 but i found that speed-wise it doesnt make a difference 2011-07-07T07:23:39 its not hard to look up a few locations 2011-07-07T07:24:06 i need to find the manhatten distance for every "target" loc for every location i add to my search queue 2011-07-07T07:24:35 antimatroid: your talking about now the association problem? 2011-07-07T07:25:02 cause in my latest bot i added this functionality 2011-07-07T07:25:08 it uses the Hungarian method 2011-07-07T07:25:17 i couldnt miss this one 2011-07-07T07:25:42 http://en.wikipedia.org/wiki/Hungarian_method 2011-07-07T07:26:35 i was thinking about pathfinding on this bi-parted graph, the association matrix 2011-07-07T07:26:46 with the manhattan distances on the edges 2011-07-07T07:26:57 but it seemed very difficult to come up with something 2011-07-07T07:27:27 but would have the advantage that it wouldnt have to evaluate all N*M distances 2011-07-07T07:27:56 but the alg. would have been much complicated, so i just went with this method instead, but now i calculate all the food/ant distances 2011-07-07T07:28:42 atm im evaluating spreading tactics 2011-07-07T07:29:03 its slow, but a potential based method is very promising 2011-07-07T07:29:26 wait what 2011-07-07T07:29:30 how do you use that? 2011-07-07T07:29:43 which part are you referring? 2011-07-07T07:29:52 hungarian method 2011-07-07T07:30:23 i use it to associate ants with food squares, the cost is the probable distance the ant would need to travel 2011-07-07T07:30:35 i.e. manhattan 2011-07-07T07:30:50 hmm, why not just iteratively search from all sources? 2011-07-07T07:31:25 well, i dont want to do superfluous pathfinding 2011-07-07T07:31:44 i would have thought it was actually just as fast if not faster to do it from all sources 2011-07-07T07:31:46 at least with a bfs 2011-07-07T07:32:01 because you find the closest food item first, then keep going with the rest 2011-07-07T07:32:03 i could be wrong 2011-07-07T07:32:12 are you using parallel pathfinding? from all sources to all target? 2011-07-07T07:32:27 or from one source to all targets? 2011-07-07T07:32:37 all sources to all targets 2011-07-07T07:32:49 whoa, i didnt realize that 2011-07-07T07:32:50 i just add all "ants" locations to the search queue, then search out till i find a target 2011-07-07T07:33:38 once i "collect" food with an ant, i'll also add that ants future location and the "to spawn" ant at the food into the "sources" for collecting the rest of the food, with their g value as when they'll be available, rather than 0 2011-07-07T07:34:23 how are you doing time wise? 2011-07-07T07:34:51 no idea 2011-07-07T07:35:03 that's my actual bot, and i just cap it for how long it's allowed to spend on it 2011-07-07T07:35:04 are you well withoin the second? 2011-07-07T07:35:08 aham 2011-07-07T07:35:19 it usually collects food within 200ms in the worst cases i think 2011-07-07T07:35:30 but i don't think you really need to leave it running that long 2011-07-07T07:35:39 it's going to collect the closest food first anyway 2011-07-07T07:37:32 who is TRavary?
