I recommend you to look through the Wiki pages in Github and the source code. It will probably answer your question. I don' know exactly what you have in mind.

@drizo The reason why routing algorithms are implemented in C/C++ is speed and some of them make use of the Boost library or CGAL. TSP for example was implemented using plpgsql only. But this depends on the use case.

@drizo pgRouting functions are written in plpgsql, the algorithms mainly in C/C++. You can find a "Getting Started for Developers" document in the project wiki: github.com/pgRouting/pgrouting/wiki/Developer---Getting-Started

What freedom do you miss with pgRouting? It's open source, so you can even change the algorithm or add your own.

comment GTFS import and pgRouting
gtfs2pgrouting was written as part of a Google Summer of Code project, but as you said, it's already a few years old. The pgRouting project would appreciate, if someone could take care of gtfs2pgrouting and make it even better. It shouldn't be so difficult, but requires either time or funding.

comment Pgrouting, pgr_dijkstra function error
Could you provide more information about OS used, version of PostgreSQL, PostGIS and pgRouting? There was a similar question (the same error ID) asked in the pgRouting mailing list some time ago: lists.osgeo.org/pipermail/pgrouting-users/2012-February/…
