Present

Tom, Omri, Eddie(Scribe), Frode, George, Bill

 

Wed. 20th Presentations:

Lee: Bio-math and GP

Omri: Auto-contruction and adaptive complexity

 

Use-Clojush in Clojush.ns

Way to make simple examples. Discouraged use for anything but simple examples.

 

Kathryn Stolee Talk

Give her system takes input/output pairs of what programmers want their code to accomplish. System returns answers to similar questions posted online.

 

Linear Push

Push is not utilizing blocks of code as well as it could if Push was linear. Ultra would be cleaner. Instructions that require blocks of code and will push blocks of code. (Ex. Start loop statements, and end loop statements with block of code in between.)

 

Question of having end statement of all statements, or a different end for each statement (ex. end_if, end_for, end_loop). Leaning towards universal end deliminator. Possibility of forcing Push to have same number of end statements as statements that start blocks.

 

Calc

Seems to be an issue with recombination.

Present

Lee, Tom, Frode, Kwaku, Karthik, Omri (scribe)

Events & news

New web framework for Clojure, Caribou, may be exciting.

We have missing notes from October 23rd…anybody have those to post?

The standalone counterclockwise is weird but still maybe what we should generally use by default.

Biomath event next Wednesday, November 20th. Among others, Lee and Omri will be presenting.

Discussion 

Multiplicative (as opposed to additive) fitness is an interesting idea! It is widely used in biological evolutionary simulations, and it could have useful implications for our problems.

On Push forth, Kwaku and Omri defended some of its virtues, while Lee and Tom took more neutral or critical stances. Ultimately, we decided that although it may have interesting features that are of potential use, none of them have any meaningful bearing on current projects, so it makes no sense to shift gears at this point.

We had a productive start of a discussion on linear GP and more specifically linear Push. The only opinions voiced were in favor. So while it looks promising, we will need to continue this discussion next week.
