16:20 < AlexWien> Hallo all!
16:21 < AlexWien> Is Cp15 online? I have a more or less urgent question about routing
16:22 <@cp15> Yes
16:22 < AlexWien> Hi
16:22 < AlexWien> In routing Navit uses the fibonacc heap variant of the dijkstras algorithm
16:23 <@cp15> Correct
16:23 < AlexWien> Further that flooding implemts the "All Shortest Path" Variant.
16:23 < AlexWien> Therefor the complete network is flooded.
16:24 <@cp15> Correct
16:24 < AlexWien> I like to introduce optionally the single shortest Path Variant of that alo
16:24 < AlexWien> of that algo
16:24 < AlexWien> Usually the singel shortets Path variant is only one line more in the algo
16:24 < AlexWien> a termination condition, that breaks, when the destination ha sbenn reached
16:24 <@cp15> I doubt you will gain much, but you can try
16:25 < AlexWien> Yes, you may be correct
16:25 < AlexWien> As I remeber All Shoretst Path, neen nearly the same Computing power like singel shortets path
16:25 < AlexWien> need nearly the same ...
16:27 < AlexWien> I asume that you adapted the algo from a existing implementation.
16:27 < BrainDamage> kinda silly question: does navit has any plans for public transportation navigation? or would that be totally out of it's scope?
16:27 < AlexWien> Spox Library ?
16:28 <@cp15> AlexWien, no, the algorithm is written from scratch
16:28 < AlexWien> using the paper by Fredman, tarjan who invented teh algo?
16:29 <@cp15> BrainDamage, there is an experimental branch regarding public transport, but the developer doesn't work on it anymore
16:29 <@cp15> AlexWien, more using wikipedia...
16:30 < AlexWien> ok, http://en.wikipedia.org/wiki/Dijkstra's_algorithm  that page under chapter Pseudocode?
16:31 < AlexWien> The reason why I ask, is we have to decide whether use the reduction variant or the map matching Variant for the foreign green route
16:31 < AlexWien> the reduction variant, seems to need 8s for each additional via point
16:32 <@cp15> That is quite much
16:32 < AlexWien> Start to VIA1 and VIa1 to dest, each 4seconds
16:33 < AlexWien> yes each route needs 3,8 s
16:33 <@cp15> On a normal PC?
16:33 < AlexWien> yes
16:33 < AlexWien> 2,4 GHz Dual core
16:33 < AlexWien> It is inner city routing in Vienna
16:34 < AlexWien> How long does it use in Munich between two Points?
16:34 < AlexWien> Its a laptop
16:35 <@cp15> I will try
16:35 < AlexWien> Or you can use vienna too,
16:36 < AlexWien> Further Can you please look at the page in thelink above, if that is the pseudo code?
16:37 < AlexWien> Because they state, that in "line13" of that pseudo code, the singel shortest Path variant can be introduced by simple adding a break condition
16:38 < AlexWien> It would save me much time, if you tell me where in route.c (route_graph_flood) in which line(s) this break condition should be added.
16:40 -!- antenna1 [~ion@dslb-188-099-081-110.pools.arcor-ip.net] has joined #navit
16:47 <@cp15> For me routing across vienna 1.07 seconds
16:47 <@cp15> (takes)
16:51 < AlexWien> Which cpu?
16:51 < AlexWien> My home pc (quad core 2,8) is possibly 4 times faster, too
16:52 <@cp15> xeon 2.13 GHz
16:53 <@cp15> In route_graph_flood after p_min=fh_extractmin(heap) you can add a break condition if p_min is higher than the values at the destination street
16:59 < Number6> The number of cores does not equate to faster computation. Even more so since navit is single threaded :-)
17:09 -!- mase_76 [~mase76@pD9FF74B8.dip.t-dialin.net] has joined #navit
17:09 < AlexWien> Its not the cores, its the faster L1,L2 cache
17:09 < AlexWien> and the fatser memory

17:10 < CIA-69> geoghegan * r4685 /trunk/navit/po/Makefile.am: Fix:Translations: Corrects the indentation of the makefile, allowing other software to parse it correctly
17:12 < AlexWien> @cp,  dst->street->value  unfortnatley does not work, how to get the values from the destination street? (dst is not a segment)

17:17 < ICE-B> hi
17:22 < Number6> Hi ICE-B
17:27 < AlexWien> test
17:28 < AlexWien> Question: How big is the initial route-graph?
17:28 < ICE-B> Number6: you need a Nick completion "i'm not a number,i'm a free man!" :P
17:28 < AlexWien> 20km 80km
17:29 < AlexWien> number6, was a nice series, i liked much
17:29 < AlexWien> maybe only  known for "old-scool" people
17:29 < AlexWien> school
17:30 < ICE-B> like us? age 39 is mine
17:30 < AlexWien> 40
17:30 < AlexWien> yes like us
17:30 < ICE-B> *gg
17:30 < AlexWien> and cp15?
17:31 < kenguest> ancient the lot of you :)
17:31 < ICE-B> year we are dusty :D
17:32 <@cp15> 39...40...41...
17:32 < AlexWien> working with navit keeps the brain young ;-)
17:32 < AlexWien> so 41?
17:32 <@cp15> AlexWien, you have to get the route segment with route_graph_get_segment
17:33 < ICE-B> so kenguest get in the line! :P
17:33 <@cp15> And of course it isn't dst, it is pos, since navit works from dst to pos
17:33 <@cp15> But nearly 40 :-)
17:34 < AlexWien> ah yes, my dijskstra implement wokrs from dest to pos, too
17:34 < ICE-B> AlexWien: but makes your hair gray
17:34 < AlexWien> i forgot, thanks for the hint
17:35 < kenguest> :D
17:35 < AlexWien> yes, autools und windows maked some of my hairs  gray,
17:35 < ICE-B> uc?
17:35 < AlexWien> autotools under windows
17:35 < AlexWien> which does not work
17:35 < ICE-B> how many germans here
17:35 < AlexWien> thanks cmake i have only a few gray hairs .....

17:37 <@cp15> AlexWien, you should have come to the camp, there was a great palatschinken-machine there
17:37 < ICE-B> WTF is palatschinken?
17:38 <@cp15> http://en.wikipedia.org/wiki/Palatschinke
17:38 < ICE-B> ah ok kaiserschmarrn
17:39 < Number6> Crepes, you heathens
17:39 < AlexWien> in vienna, some years ago, once Museumsquartier (MQ) opened, there was a shitting machine
17:40 < AlexWien> 10 meters, with about 8 steps
17:40 < ICE-B> LOL
17:40 <@cp15> No, no schmarrn :-)
17:40 <@cp15> Here is a picture of it: http://7.asset.soup.io/asset/2291/8631_23b1_960.jpeg
17:42 < AlexWien> First time that i cannot terminate a crashed eclipse process under windows?
17:42 < AlexWien> any ideas? Taskmanager cannot terminate it
17:43 < ICE-B> yeah back it @ 600 °C
17:43 < ICE-B> sorry bake
17:44 < AlexWien> http://gizmodo.com/5345499/turn-your-food-into-poop-with-a-cloaca-machine
17:44 < AlexWien> the shitting machine
17:45 < ICE-B> crazy,isn't it?
17:46 < Number6> wtf!
18:09 < Number6> How can I disable things in CMake, like maptool?
18:13 < AlexWien> Another question to cp: Do the segments of navit map have an (unique) segment id? I did not found an id
18:20 < AlexWien> is my irc broke? or is nobody commiuncating now?

20:02 <@cp15> Looks like you have a problem with speech output
20:03 <@cp15> And it would be helpful if you could use the newest svn version
20:03 <@cp15> korrosa, probably a problem with the provider... I assume you can reach maps3.navit-project.org and maps9.navit-project.org?
20:04 < danieltm> the new svn doesnt work the tab
20:04 < korrosa> cp15: Yeah, I've literally got the entire internet, except for Germany. Looks like we've finally been cut off...
20:05 <@cp15> danieltm, have you installed rsvg-convert as advised?
20:05 <@cp15> maps9 is also in germany, but traceroute looks better
20:06 < danieltm> wasnt compilable.
20:06 <@cp15> And maps1 also
20:06 <@cp15> What error do you get?
20:06 < korrosa> cp15: Ah well, looks like something's gone wrong for the moment then - I'll try again later!
20:07 < danieltm> there are dependencies i couldnt get working
20:07 < danieltm> error with glib when glib is installed
20:07 <@cp15> Have you installed the appropriate devel-package also?
20:07 < danieltm> glib also up-to-date
20:08 < danieltm> sure
20:08 <@cp15> Then a complete build log would be helpful. And please use pastebin.com and don't paste it here
20:09 < danieltm> ok...ill try now to work around speach and than ill try to compile the s vn....thx for the help
