05:39<Samu>I picked a savegame of NoCAB, loaded it in 2051
05:40<Samu>he uses only aircraft, mostly traveling on diagonal directions (horizontal, vertical lines on the image)
05:40<Samu>from 2051 to 2052, the difference was that I applied the speed penalty patch
05:40<Samu>the difference is very noticeable

09:33<Samu>something's not quite right on my testings
09:35<Samu>gonna wait 5 years to refresh the timetables and cargo values
09:35<Samu>will look again at the profit on the 6th year
09:36<Wolf01><Samu> something's not quite right on my testings <- the execution state
09:36<Samu>ah, interesting
09:37<Wolf01>You focus too much on a single value without even thinking if that breaks other 100 things
09:37<Samu>i am trying to figure out what it is
09:38<Samu>i think 5 years is enough for every vehicle to restart their routes from order 1
09:38<Samu>loading unpatched savegames might be a bad idea
09:38<Samu>it is using old data
09:40<Samu>if by then train profit is still barely changed, then I don't really know what went wrong
09:40<supermop>yo
09:42<Samu>feels like trains have a different profit formula than the other vehicle types
09:44<Samu>hi supermop
09:44<supermop>i don;t think i every notice individual vehicle profit
09:45<supermop>once i can afford more than one line, the cash flow is such it rarely makes sense to examine
09:49<Samu>okay, i can't really test this like I'm doing
09:49<Samu>industries close on one of the samples, but not on the other

11:00<Samu>does the cargo lose value if they wait too much at stations without being loaded?
11:00<FLHerne>Samu: No
11:00<Flygon__>Your ratings tank tho
11:00<FLHerne>If you leave it for a long while, it evaporates
11:00-!-Flygon__ is now known as Flygon
11:00<Flygon>That too
11:01<Samu>well, then... i have no idea what's wrong
11:02<Samu>when delivering cargo, payment isn't always the same
11:02<FLHerne>"Every 2.5 days station ratings are computed; ratings can't change by more than 2 points per cycle, except after crashes."
11:03<FLHerne>Crashes lose 63 %points
11:04<FLHerne>So, if you had a station with a rating <35%, you could improve the rating by crashing a vehicle next to it
11:04<FLHerne>Gah, not explaining right
11:05<FLHerne>If you increase the service suddenly, you can cause the rating to improve faster than it normally would in the short term
11:05<FLHerne>No, that was a totally useless idea
11:07<Samu>ships profit behave as i expected, road vehicles too, aircraft too, but trains... their profits are barelly changed with the speed penalty
11:08<Samu>I don't understand
11:08<@Alberth>from 100 to 120 is not a big change in time
11:08<@Alberth>from 10 to 30 is much bigger
11:09<@Alberth>ie at slow speeds, the relative impact of a faster vehicle counts much more than at high speeds
11:10<Samu>i saw trains with penalties ranging from 2% to 5%, of course the testing conditions are quite varied, but
11:10<Samu>aircraft got a penalty from 37% to 41%
11:10<@Alberth>10km/h -> 20km/h is a speedup of 100%
11:11<@Alberth>100km/h -> 110km/h is just 10%
11:11<Samu>ship penalty got a penalty of about 14%
11:11<@Alberth>so if your relative fast train is faster or not doesn't make a large difference
11:11<Samu>road vehicles - no change, as I intended
11:13<Samu>i know it depends a lot on how many diagonals are there on the routes, but still.... 2%-5% is quite low
11:14<Samu>but i see
11:14<Samu>trains are already fast
11:14<Samu>aircrafts are also faster
11:14<Samu>but got a much bigger impact on their profit
11:15<Samu>brb let me check my code
11:16<@Alberth>same cargo?
11:16<@Alberth>cargo can also modify the impact on being late
11:16<Samu>er, not really, just loaded an old save and let it run for a few years
11:16<Samu>then compared with 1.6.1
11:16<Samu>the same savegame
11:17<Samu>but i understand that it needs at least a full complete schedulle for every vehicle to refresh cargos values to the new speeds
11:18<@Alberth>that would make sense, cargo departure and arrival times are stored and used in these calculations
11:19<Samu>return (this->type == VEH_TRAIN) ? (this->direction & 1) ? speed * 3 / 4 : speed / 2 : speed * 3 / 4;
11:19<Samu>this is for trains and road vehicles
11:19<Samu>return (this->direction & 1) ? speed : speed / 2;
11:19<Samu>this is for ships and aircraft
11:21<Samu>seems that the problem is there at "speed / 2" - trains on diagonals
11:22<Samu>this alone makes the trains have equivalent travel times, but then, the profit formula... seems to be negating my effort

11:24<@Alberth>there is also a distance involved in payment, afaik
11:25<@Alberth>the route of the train has nothing to do with that
11:25<@Alberth>the route only affects how fast the train arrives at the destination

14:39<V453000>http://us2.factorio.com/assets/img/blog/fff-155-pipes-and-pump.gif in the last months I learned that making a tileset for pipes like this is utter hell ... but compared to making tracks for openttd it's still awesome :D
14:40<supermop_>V453000: i read that as 'slap some photo like of you'
14:40<supermop_>i think thats what i should do - my face as environment dome
14:40<V453000>that's optional supermop_ :P
14:41<supermop_>embarassing - i forgot how to set a folder to show file extensions
14:44<Samu>sum of all the sublocations of each track that a vehicle steps into, to get the total distance travelled
14:45<V453000>supermop_: I just use total commander for that
14:45<V453000>but I guess you could google it :P
14:46<supermop_>i had to google it
14:46<Samu>or just the sum of diagonal directions~
14:46<supermop_>something i've done 1000 timess tho
14:47<V453000>XD
14:47<Samu>adjusting profit formula may an alternative
14:47<Samu>an alternative to the speed penalty
14:48<Samu>Altered Manhattan perhaps
14:49<Samu>but road vehicles will suffer
14:52<Samu>will openttd ever have diagonal roads?

15:00<Wolf01>*both
15:00<andythenorth>:P
15:00<andythenorth>both are bots?
15:05<Wolf01>Any improvement with NRT?
15:05<andythenorth>nothing so far
15:06<andythenorth>I will poke at nml…but life
15:06<Samu>so i was thinking of this formula I'm inventing
15:07<Samu>it's based on DistanceManhatan
15:07<Samu> const uint dx = Delta(TileX(t0), TileX(t1)); const uint dy = Delta(TileY(t0), TileY(t1)); return dx + dy;
15:07<Samu>instead of return dx + dy
15:07<Samu>it would be return dx + dy + Delta(dx, dy);
15:09<Samu>or maybe - Delta(dx, dy)
15:10*andythenorth ponders
15:10<Samu>have to think this better
15:10<andythenorth>could we reduce the inertia to forks and patches?
15:11<andythenorth>assumes git, sadly https://github.com/koppen/redmine_github_hook
15:12*andythenorth can’t find a hghub
15:13<Samu>is this a known formula, or did i make it up?
15:14<Samu>trying to google and can't get anything similar
15:14<Wolf01>Are you just adding numbers or it has some sense?
15:15<andythenorth>looks like first order differentiation
15:16<andythenorth>as far as I can remember from 20 years ago
15:16<andythenorth>Eddi|zuHause will know
15:16<Wolf01>isn't it just 2*dx+dy?
15:17<Wolf01>Oh, no, it has different vars
15:17<Samu>return dx + dy - Delta(dx, dy);
15:17<Samu>I am "shortening" the distance because vehicles go faster on diagonals
15:18<Samu>when calculating payment, the distance it gets is smaller
15:18<Samu>but i am also wondering if this makes any sense
15:18<Wolf01>So, you are changing the distance when the problem is the speed?
15:18<Samu>yes
15:20<_dp_>Wolf01, who said speed is the problem? ;)
15:21<_dp_>It all depends on what metrics you consider to be right :p

15:33<oftcrash>Anyone familiar with graphviz?
15:34<oftcrash>I'm getting the following error when compiling FIRS locally when its trying to generate the SVG:

15:43<oftcrash>python 2.7.5
15:44<oftcrash>I used brew to install graphvis
15:44<oftcrash>it looks like its creating the docs/cargoflow.dotall file
15:44<andythenorth>I’m on 10.10.5 with graphviz from macports
15:44<andythenorth>hmm
15:45<oftcrash>I might have ports installed too. I'll try uninstalling and reinstalling
15:47<oftcrash>or not. I seem to have uninstalled it
15:47<oftcrash>the homebrew copy seemed up to date though
15:47<oftcrash>maybe its something in 10.9
15:47<andythenorth>my experience, don’t have macports and brew both trying to manage ports :)
15:48<andythenorth>causes trouble
15:48<oftcrash>yeah, I think that's why I got rid of macports - it was a few years ago
15:49<andythenorth>oftcrash: does it work with vanilla FIRS?
15:49<andythenorth>just wondering if it’s the file, or graphviz
15:49<oftcrash>good question, Let me check

19:28<_dp_>Samu, what's so good about 29?
19:28<Samu>travel time parity
