Updates on Collaborations and Lab News
Zeke and Micah busy with Div III work

David Gagne Coming to UMass. Welcome, David!

Lee met with Ranjan Srivastava last week. Recall that possible projects include: Also to note : Ranjan's lab uses Common Lisp.
 * Modeling biochemical processes with GAs
 * Using some form of GP to evolve fabrication recipes for electrodes
 * Evolving gyroids.

Discussions with Kourosh Danai and his grad student Bill LaCava

Picked up work with David Clark again

Lee's Linear Operator work and Tom's ULTRA work

 * Still having issues on calculator problems.
 * Right now the problem's been simplified to single-digit entry
 * Problems might lie in the test cases? Tom thinks that we need more test cases and that errors might be propagated by dependencies between the test cases.
 * ULTRA not doing the kind of recombination we want - Lee thinks that from the data he's seen in the runs, we're not exploring the space the way we would like to.
 * Want modularity in the handling of the digits in the calculator problem
 * Tom's suggested: tag space inheritance? His argument is that inheriting code that's already tagged lends itself to modularity and aggregating genetic change. Lee's objection is that this messes with the functioning of uniform mutation and has high potential for bloat.
 * Another idea is to try out the operators with smaller problems.

GPTP

 * Emma and Tom to meet tomorrow to work on a draft. If it seems that this wouldn't work out for GPTP, will need to punt.

Workshops

 * Want a workshop paper on either ULTA or environments
 * Lexicase can be an undergrad workshop paper
