A simple trick if you want to do start-via-via-...-via-end optimization
like TSP is to use TSP and artificially set the distance between end and
start locations to zero and this will keep those two city bound
together. Then in the result just remove that link.
This will allow the same code that solves TSP round trip to also
optimize the vis points between a start and end trip.

Emne: Re: [OSRM-talk] Route Optimizing
Hi Jonas,
Are there any ambitions to create something like an optimization for route
stops?
And when not do you know any other way to do this via rest request?
If you are thinking of the TSP -
https://en.wikipedia.org/wiki/Travelling_salesman_problem - then it is a simple problem of "I
need to visit X places after each other, please optimize the order to visit those places in".
The solution is well-described in the WikiPedia link. You can write a little JavaScript, Python or
whatever - and optimize on either distance or time. It is fairly simple, and all you use OSRM for
is getting the costs. If you want as few calls to the OSRM-server as possible, then have a look at
the "table"-service (
https://github.com/Project-OSRM/osrm-backend/wiki/Server-api#available-services
)
Best regards,
Greg
