Hi all,<br>
<br>
I have had a couple of requests for more information on what our Google Summer of Code students developed this summer. The following pages give a pretty good overview of their projects and how to use them.<br>
<br>
Mukul added this:<br>
<br>
<a href="https://github.com/pgRouting/pgrouting/wiki/Details-and-how-to-use-guide-" target="_blank">https://github.com/pgRouting/<u></u>pgrouting/wiki/Details-and-<u></u>how-to-use-guide-</a>.<br>
<br>
it is located in git on branch "gsoc-partition" in src/partition/ directory. Look at the test directory for examples.<br>
<br>
Razequl added this:<br>
<br>
<a href="https://github.com/pgRouting/pgrouting/wiki/GSoc-2013-Project-Information" target="_blank">https://github.com/pgRouting/<u></u>pgrouting/wiki/GSoc-2013-<u></u>Project-Information</a><br>
<br>
it is located in git on branch "gsoc-vrp" in src/vrp_basic/ directory. Look in the test directory for examples.<br>
<br>
If you have questions, feel free to ask, Mukul and Razequl will probably be on the lists for a while before they have to start tackling their next years course work. And Daniel and I can also field questions on these.<br>

Hi<br>
<br>
Is it possible to have summary of the features that Mukul and Razequl<br>
work adds to pgrouting?<br>

Mukul and Razequl,<br>
<br>
Congratulations on your successful completion of GSoC!<br>
I'm sorry that Daniel and I have been very busy with our own projects<br>
of the recent past and have not been engaging more with you guys.<br>
Please make sure you complete the final code submission and<br>
requirements for Google so you will get paid for all your hard work.<br>
<br>
For next steps, I see Daniel has merged the the develop branch into<br>
the vrp branch. This will make it easier to eventually merge your code<br>
back into the develop branch for our 2.1 release in the future. I<br>
think we need to add some methods to generate the distance matrix<br>
based on a list of locations. We can write a simple Euclidean distance<br>
generator for fast demos and write a separate function that uses<br>
one-to-many Dijkstra function to generate the distance matrix.<br>
<br>
Daniel, any thoughts on this? Did you have any specific plans with this?<br>
<br>
I want to do some testing on the partition projects, and look at<br>
performance and memory usage on large graphs. Mukul is going to look<br>
at creating a trsp-partition branch to see if he can integrate the<br>
partition model into TRSP.<br>
<br>
For both these projects, I want to review at the APIs and see if I can<br>
make them consistent with our new module of reusable generic types or<br>
extent the types as needed. I also want to review them for usability<br>
changes like removing fixed table or column names, etc.<br>
<br>
>From my point of view, these tasks will have to wait for some free<br>
time which will be at least 2-3 weeks out if then.<br>
<br>
I'm glad you both had a good summer with GSoC and that you will have<br>
time and interest in continuing to expand you projects and support<br>
pgRouting even if it is at a lower effort level because of class work<br>
again.<br>
<br>
Thanks again for your efforts and significant contributions.<br>
<br>
-Steve<br>
