CI-lab meeting 04/09/2014

Present : Karthik (scribe), Omri, Bill, Tom, Lee, Jake, Kwaku (Hangouts)

Omri : Working on Div III : Website with quantum computer simulator/visualizer. Immediate next task : Circuit diagram component.
Managed to calculate tangle finally.

Jake : Div III stuff – working on rendering issues.

Brevis not scaling well enough? Rotation math/confusing stuff – so evolve this instead.

The long term issue on producing GP results that are “human-understandable”/interesting issues on protected division ending up with a no-op.

Generative tests, etc – to potentially solve generalization problems. Generalization is still a problem to solve. Validation within runs. Tom’s training/test split.

Co-evolutionary geography.
Spatial co-evolution – Quicker, Fitter and Less bloated

Lecture meeting/seminar – April 29th/5pm –
http://www-unix.ecs.umass.edu/~gong/
Potential resonance with Monte-Carlo tree search.

Why Turing machines and “Go” aren’t equivalent in power :

Bill – code overhaul/changed instruction set. Some changes in the hill climber, etc.
Wind turbine stuff – target being human competitive.

Tom – Working on the Lexicase paper. /Article revision.

Frode – Simplification paper/poster for GECCO. Looking at journals where this might be a good fit.

GPTP :
Travel etc.

Clojush : eval push limit
Other things on Clojush/Java integration :
– Potentially introduce a new Push instruction
– Asynchronous timeout to prevent instructions that take arbitrarily long.

Notes and Lab Page

  • Get Karthik up to speed for posting lab notes
  • Update lab pages when possible: especially fly section

Simplification Paper – Journal Article

  • Put together poster paper and Frode’s workshop paper

Laziness Can Get You Into Trouble

Lee’s Heisenbug memory leak

Tom’s Selection Comparisons Lexicase/Tourney

  • Try graphing lexicase selections with total error on the x-axis instead of rank
  • Maybe look at minimum error by test case vectors to see if they are similar or different between runs. Could (but not necessarily) show whether or not the runs are exploring similar or different search spaces.
