[OSRM-talk] Shortest route given start and end point

[Julien Coupey]

Hi,

I have used a strategy close to what is described in the mentioned 
ticket (see my comment there). It did work for another project to add 
this specific feature to an existing TSP solver.

As for the "computationally expensive" side, it is all a matter of 
trade-off between computing time and solution quality. My experience is 
that 1000's can still be tackled in a matter of seconds with very decent 
results.

Hope this can help,
Julien
