Clojure code for a simple genetic programming system, for demonstration purposes.
(ns evolvefn) ;; Lee Spector (lspector@hampshire.edu) 20111018
;; This code defines and runs a genetic programming system on the problem
;; of finding a function that fits a particular set of [x y] pairs.
;; The aim here is mostly to demonstrate how genetic programming can be
;; implemented in Clojure simply and clearly, and several things are
;; done in somewhat inefficient and/or non-standard ways. But this should
;; provide a reasonable starting point for developing more efficient/
;; standard/capable systems.

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a
