= Notes from lab meeting =

Admin

 * GECCO receipts - get to Lee with signed forms

GECCO thoughts

 * Our talks were well-received
 * Maarten Keijzer ideas: Push Fourth (one stack), Bad Hash Function (tag based on content)
 * GP best paper may be related to our work
 * Discussion of GP as optimization vs. program induction
 * Discussion of automatic software repair and Simon Harding's multi-type Cartesian genetic programming.
 * Emma: could see GP as a front-facing part of other hybrid ML algorithms, or as an exploratory technique to understand data better, as opposed to a last-ditch effort when other things don't work.

Steady-state GP

 * Lee gave a description
 * We may be interested in trying out steady-state PushGP
 * Also, not sure of relation to ALPS (Age-layered population structure)

Rewarding Tag Usage

 * Kwaku and Emma plan to investigate rewarding tags
 * Encouraging modularity explicitly in the fitness function may be useful
 * Difficult to know what to reward
 * Other tag ideas include a shared tag-space in the whole population, or hereditary tag spaces

Blog

 * Emma wants to start a blog to encourage communication with the rest of the EC community about issues we think are important
 * May concentrate on understanding problems

Next Meeting
