Hi All, I'm working on porting a new TSP algorithm into pgRouting. With the follow example query: select * from tsp('select id as source_id,x,y from tsp_00', '1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22', 1); Is the expected result a loop starting at node 1 and ending back there? -Steve
