GPTP

How to make inferences in GP / initial populations / COSMOS

• The emphasis should be about how to make inferences about how well a GP system works, especially in comparison to another method or system.
• About the efficacy of GP.
  • What you need to do to make claims about your system and comparisons.
• Not really about choosing a population size.
• Includes a new experimental procedure.

ULTRA

• Better on Pagie-Hogeweg and Bioavailability
• Program sizes are much lower.
• Tom will start writing this up soon.

GECCO Stack-Based GP Workshop

Multiple output multiplier

• Tom will work on getting this running in Clojush

Environments

• We decided that the current return_tagspace and return_tag_ instructions are enough for tags in environments.
• Maybe try PH or Bio if we have extra cluster cycles.

Lexicase-based Mate Selection

• We discussed briefly how we might do a non-random mate selection based on lexicase.
