7:00 – 5:00 VTX

• Learning: Genetic Algorithms
  • Rank space (probability is based on unsorted values??)
  • Simulated annealing – reducing step size.
  • Diversity rank (from the previous generation) plus fitness rank
• Some more timing results. The view test (select count(*) from tn_view_network_items where network_id = 1) for the small network_1 is about the same as the pull for the large network_8, about .75 sec. The pull from the association table without the view is very fast – 0.01 for network_1 and 0.02 for network_8. So this should mean that a 1,000,000 item pull would take 1-2 seconds.

• mysql> select count(*) from tn_associations where network_id = 1;
   11 
  1 row in set (0.01 sec)
  
  mysql> select count(*) from tn_associations where network_id = 8;
   10000 
  1 row in set (0.01 sec)
  
  mysql> select count(*) from tn_view_network_items where network_id = 8;
   10000 
  1 row in set (0.88 sec)
  
  mysql> select count(*) from tn_view_network_items where network_id = 1;
   11 
  1 row in set (0.71 sec)

• Field trip to Wall NJ
  • Learned more about the project, started to put faces to names
  • Continued to look at DB engines for the derived DB. Discovered WebScaleSQL, which is a collaboration between Alibaba, Facebook, Google, LinkedIn, and Twitter to produce a big(!!) version of MySql.
  • More discussions with Aaron D. about control systems, which means I’m going to be leaning on my NIST work again.
