Hello Everyone,
This is my weekly report for week [6] (Jul 7th -Jul 12th).The report
can also be found in project wiki [1].
What did I get done this week?
- Created the pull request in which my weekly progress can be
reviewed.[2]
- Completed the coding of SQL functions that are pgr_mrt.sql and
_pgr_mrt.sql.
- Fix the signature of Lengauer Tarjan dominator Tree. (Rename from
LTDTree to lengauer_tarjan_dominator_tree).
- - Changed the name of the function in LTDTree.c file to solve the
errors.
- - Changed the name of functions in pgTap tests to proper testing.
- - Changed the signature of the function in pgrouting--3.0.0.sig file.
- Able to read data from PostgreSQL for pgr_mrt().
- Made the c++ containers and added
boost::lengauer_tarjan_dominator_tree algorithm
for an undirected graph. But till now it returns 0 rows.
- Added pgTap tests files with zero tests in spanningTree/mrt the
directory that contains: mrt-edge-cases.sql, mrt-innerQuery.sql,
no_crash_test-mrt.sql, pgr_mrt_types_check.sql.
What do I plan on doing next week?
- Complete coding of c++ containers and add
boost::lengauer_tarjan_dominator_tree for both the undirected graph and
the directed graph.
- Write some tests for no_crash_test-mrt.sql and mrt-edge-cases.sql
- Prepare user documentation for two graph common spanning tree.
Meetings attended in this week
No meeting was scheduled.
Am I blocked on anything?

Thanks
