[pgrouting-dev] testing TSP example fails

[Stephen Mather]

Hi All,

More TSP for today.  In testing the example in the docs against the 
example data, I get what is to me a cryptic error:

SELECT * FROM pgr_tsp('SELECT id AS source_id, x, y FROM 
vertex_table','2,7,11',7);

ERROR:  Error TSP fail to findEulerianPath, check your distance matrix 
is valid.


********** Error **********

ERROR: Error TSP fail to findEulerianPath, check your distance matrix is 
valid.
SQL state: XX000

I get an entirely different error against my OSM data, but one error at 
a time... .

Best,
Steve
