Re: [OSRM-talk] Does osrm-routing deal only with ordered points

2018-03-14 Thread Xavier Prudent 
Thank you Nico and Daniel,

I guess that is so far all I need, I will now dig through the exemples.

BTW, the level of development & documentation of osrm is quite impressive.

Regards,
Xavier

 Dear all,

 Given 4 points A,B,C,D
 osrm makes a nice job searching for a route that goes through
 A->B->C->D.

 Is that also able to estimate the optimal ordering, not necessarily the
 given one?

 Regards,

 Xavier

Re: [OSRM-talk] Does osrm-routing deal only with ordered points

2018-03-14 Thread Daniel Hofmann 
Also check out

https://github.com/mapbox/node-or-tools#node-or-tools

which you can use on top of the routing engine's distance matrix output.

The repository contains an example how to do this with further optimization
constraints.

Hope that helps,

Re: [OSRM-talk] Does osrm-routing deal only with ordered points

Yes, you are right.
I'm sorry I give you an old link, here the current version documentation:
http://project-osrm.org/docs/v5.15.2/api/#trip-service

The route service finds the fastest route between coordinates *in the
supplied order*.

The trip plugin solves (try to) the *Traveling Salesman Problem. *(I think
it's what you need)
Please keep in mind the roundtrip option (route returns to first location)
In the last version there are two new option source/destination if you want
to fix the first and the last point and reorder the others, otherwise the
service use the supplied points in any order to reach the goal. (please
follow the supported combinations of roundtrip, source and destination
according to the table)

Hello Nico,

Thanks for that fast answer,
So if I understand well, the route service expects an order, while the trip
service can estimate this order, right?

Hi Xavier,
you can use the trip service:
