VRP with a single location #291
Description
The following VRP problem with a single location (note that all location indices are 0) but with a 2x2 matrix returns the expected solution with zero cost.
However, if the matrix is replaced by a 1x1 matrix, then vroom tries to connect to OSRM and fail with the following error {"code":3,"error":"Failed to connect to 0.0.0.0:5000"} (since there is no lat/lon, even if the connection succeeds, the query would fail anyway).
I believe the offender is if (_matrix.size() < 2) { check on src/structures/vroom/input/input.cpp:332 inside solve function.
Is the check against 2 is necessary? It seems to me that 1 does the job well.
