Both `_dup_times` and `_dup_items` are risky and can place very large numbers of items on a stack if the value on the `:integer` is large. This limits both `_dup_times` and `_dup_items` so they never make a stack have more than `max-stack-items` entries. This change was motivated by `OutOfMemory` errors we were receiving when doing runs. This is somewhat modeled after similar limits in Clojush, but we chose to not introduce an `atom` and to instead just define a constant in this namespace. That may not be as flexible as people would like, and we can move to the `atom` solution if necessary.
propeller
Yet another Push-based genetic programming system in Clojure.
Usage
To run PushGP on the default genetic programming problem
from a REPL, load propel.core into your REPL (i.e. lein repl),
and run (-main).
To run PushGP on the default genetic programming problem from
command line, execute lein run. Command-line arguments may
be provided to override the defaults specified in -main, for
example, lein run :population-size 100. You can use something
like lein run | tee outfile to send output both to the terminal
and to outfile.
CLJS Usage
Development
Run in development:
yarn
(mkdir -p target && cp assets/index.html target/)
yarn shadow-cljs watch app
shadow-cljs will be installed in node_modules/ when you run yarn.
:dev-http specifies that target/ will be served at http://localhost:8080 .
REPL
After page is loaded, you may also start a REPL connected to browser with:
yarn shadow-cljs cljs-repl app
Once the REPL is loaded, load the core namespace with:
(ns propeller.core)
Calling (-main) will run the default genetic programming problem.
Description
Propel is an implementation of the Push programming language and the PushGP genetic programming system in Clojure.
