Research (Programming) 2:00:00 [3]
shoes: Blocker

Added some sampling techniques to the query engine. Still some work to go before I can actually start tuning the Evolutionary Algorithm.

HW3: problems from section 3.1.

Sunday Mar 26 #

Practice (Problems) 3:00:00 [4]
shoes: MA5140

Corrections to HW2, which I'll resubmit. Most were minor, but there were a couple proofs that had to be significantly reworked. A good exercise in cleaning up one's logic.

Practice (Programming) 2:30:00 [3]
shoes: Blocker

Finished the optimizer. It helps, but doesn't solve the problem of having to read all the rows when no block criteria have been created. Therefore, I added two options to the query engine: sample the data (actually read a specified percentage of blocks meeting the criteria) or gather block stats (essentially sampling with the percentage set to zero). Both allow running queries quickly to generate a new generation in the early going when running the full query takes a long time.
