[postgis-users] Salesman problem

[Gustavo Ces]

Thanks all!

I ´ve found pgdijkstra module, but a newbie like me doesn´t understand 
anything. There is an schema description in the file.sql, before function 
definitions. Do all the funcions  work with that schema or that schema is 
the result of apply some pgdijkstra-functions to my street network? ( 
functions create topology or need a created topology to work?)
My source data is a simple network i draw in a client and save in PostGIS. 
The next step is to transform this schema in the file.sql schema? It seems 
that some of pgdijkstra functions make something like that but i´m not 
sure...
Sorry for ignorance, but where can i found more info?
