Hi,<br><br>Waking up a sleeping thread after a long time! ;-)<br><br>Well, I have corrected the problem with float values in distance matrix and negative costs. So, the APSP algorithm seems to be working fine now. <br><br>
Updated the gsoc-tdsp branch with the code[1].<br><br>I also wrote a tutorial to get started and try out the APSP algorithm using pgRouting[2].<br><br>Any inputs are welcome!<br><br>[1] <a href="https://github.com/pgRouting/pgrouting/tree/gsoc-tdsp">https://github.com/pgRouting/pgrouting/tree/gsoc-tdsp</a><br>

<br>
Splendid! Great work!<br>
<br>
What about negative costs - I think there shouldn&#39;t be any negative<br>
costs in distance matrix. According to our convention, edges with<br>
negative costs are not included in a graph for shortest path<br>
calculation in Dijkstra, A* and Shooting*.<br>
