[pgrouting-users] Housenumbers as multiple stops route with Pgrouting

Hello Matteo

In general, you need to figure out the pgRouting working graph.
Based on your small explanation:
For example, suppose that you have one street segment as a graph (from one
intersection to another) and the houses around it:
One "segment" graph
   1    3    5      7     9     11
A-------------------------------------B
    2  4       6     8    10      12

So now you have a 13 segment graph.
A-1-2-4-3-5-6-7-8-9-10-11-12-B
PostGIS/pgRouting do not have a function that does this. you would need to
create your transformation function (if needed).

About what algorithm to use
You might as well see and do the examples of the proposed functions "with
Points"
But if you are talking about pgr_pickDeliver then you might as well use it
with the `pgr_withPointsCost` function to get the matrix values needed as
input

Regards
Vicky
