Lee: send out a CI Lab email about Zeke’s webgp thing<\/a><\/p>\n GECCO deadlines: Jan. 15th for abstracts, 29th for papers, and they seem very serious about sticking to these deadlines<\/p>\n There will probably be a meeting next Wednesday, regular time, last of the semester<\/p>\n All println<\/strong> calls to prn<\/strong><\/p>\n Option to report percent of parens in a given program or population<\/p>\n Separate out “report-best”, so that it can be independent from “fitness”<\/p>\n It works (yay!)<\/p>\n Some of the syntax is different<\/p>\n Next steps are to include tags and\/or any kind of genetic programming functionality<\/p>\n Lee recommends aiming to make it usable for next semester’s Genetic Programming students<\/p>\n Frode has been working on this, with a lot of good documentation and tutorials that can be seen in the Clojush wiki<\/a><\/p>\n Lee is unsure where we should go from here: where to host documentation and tutorials of Clojush and\/or of Push in general<\/p>\n Frode has been thinking about doing experiments related to both of these<\/p>\n Lee pointed out that these are separable projects, and that one possible off-shoot is to look into some Excel\/Clojush integration<\/p>\n Bill has been trying to solve a harmonic oscillation problem<\/p>\n He has a number of interesting non-standard genetic operators that he’s been working with, and is having difficulty knowing\/finding the right parameters<\/p>\n Lee suggested taking a step back and trying more standard genetic operators, and also just “seeing what works”<\/p>\n Karthik would like to do some experiments here, possibly related to the calculator problem<\/p>\n Lee described a lot of recent efforts around automatic modularity, and the various issues surrounding modularity in general<\/p>\n Kwaku has been working on identifying modularity at run-time, hoping to find good metrics for modularity in arbitrary programs (which reminds Lee of some old experiments testing the “compressibility” of execution traces in Push programs)<\/p>\n Thom thinks he’s recently come upon some general solutions to the word count problem (yay!)<\/p>\n Tom’s using training AND test cases, where training cases are seen during evolution, and test cases are only used to test the generality of solutions that arise from the evolutionary loop<\/p>\n Lee has a sort of rotating-auto-generation training case thing, but notes that he doesn’t know what’s going on between generations because of the set of cases shifting under his feet<\/p>\n Tom suggests making one large auto-generated list of cases, choosing a random subset for evolutionary selection, and using the whole thing for comparing different generations<\/p>\n Lexicase seems to have issues with errors measured in floating point, because selection here will be too elite<\/p>\n So Tom has been experimenting with a non-elite lexicase based on relative ranking (“ranked lexicase”): notably, on the bioavailability problem, it was better than normal lexicase, but equal to standard tournament selection<\/p>\n There is now a working qgame API<\/a>, and a GUI<\/a> in the works<\/p>\n","protected":false},"excerpt":{"rendered":"
