Today I've updated my tutorial about pgrouting on win32 (for PostgreSQL 8.3.Y). TSP is now available. I've to change tsp_astar_directed() function (using astar_sp_directed() instead of astar_sp_delta_directed()

The tutorial is available at http://www.davidgis.fr/documentation/pgrouting-1.02/

As usual, link for binaries is http://www.davidgis.fr/download/pgRouting-1.02_pg-8.3.3.zip

Have fun !
