13-Oct-2008: LRP courtesy of ABC

• SVN Revision 25.
• Added ABC's amazing LRP plots.
• Slowly importing data; about 60% (?) done for the main rumble
• I have an idea to speed up scoring/uploads, but it's major work so not this week...

11-Oct-2008: Transitions

• SVN Revision 23.
• Based on | ABC's announcement, relaying is now turned off for faster uploads.
• Importing is still in progress:
  • Minirumble finished yesterday.
  • Roborumble is only 30% done, lots of battles still left
  • I also need to import any new battles since the 7th
• Importing is a great high-load test; improved upload speed in a few areas, but it can still slow down if several clients (including the importer) all try to upload simultaneously.
  • The bottleneck is the rating update process, querying all pairings for the two competitors is expensive.

7-Oct-2008: Import in Progress

• Finished testing import utility (just a Perl script) which takes battles_*.txt files and re-submits them to the server.
• All battle data from ABC's backup directory was imported to the new server this morning.
• Nanorumble data as of 15:30 PDT imported to new server (starting small).
• Currently importing Microrumble data... complete!
• Minirumble and Roborumble will take quite some time, I think. Normal results uploading may be slow during this period ... --Darkcanuck 01:19, 9 October 2008 (UTC)

6-Oct-2008: All Users Welcome

• SVN Revision 19
• Fixed a major bug introduced in rev 11 where new upload users could not be added.
• Tentative PL scoring column added to ranking table
• Added some additional stats to the details pages, including standard deviation for APS.
• Added import functionality; currently testing an import of ABC's data on my local test server.

5-Oct-2008: Sorting for Fun & Profit (+ Glicko-2)

• SVN Revision 14 15
• Pairing and battle detail views can now be sorted like the rankings view.
  • Finally you can group your worst ProblemBots together!
  • PBI, Expected scores still use Glicko ratings, looking for feedback now that both Elo & Glicko are displayed together.
• Added Glicko-2 ratings; uses existing Glicko rating as initial value. Let's see how this works out.

4-Oct-2008: Elo makes its debut

• SVN Revision 11
• Added Elo scoring based on old server's code.
  • Includes rating "jumpstart": bots with >50 battles start at an ideal rating based on APS.
  • This is causing slower uploads but should clear up once all bots get Elo ratings.
• Ratings updates now done after every upload (no more periodic update).
• Ratings use all available pairings for each update (slow, but this is the classic method).
• Streamlined battle results table to use only one record per battle (was two); user data now in separate table.
  • Table size down to 30% of previous.

27-Sep-2008: Setting Priorities

• Added priority pairings and battle number output to clients. I missed this last time around.
• Tweaked database performance for results uploading.
• Ratings rebuild has caught up, so rankings are now up-to-date within the last minute!
• Melee rankings are starting to fill out.
• Many thanks to GrubbmGait and [Darkstorm]] for generously contributing battles

25-Sep-2008: Build it and they will come?

• One week, 4 clients uploading without any major issues. 68,148 battles in the general rumble so far.
• No outstanding "known" bugs at this point (fingers crossed).
• Added Glicko ratings and flushed existing pairings & ratings yesterday. That means the ratings are still rebuilding, and will probably catch up sometime tomorrow.
• Added table sorting on the main rankings pages.
• Added support for melee (works) and teams (my client doesn't work for teams so this is untested).
