-main

(-main & args)
Runs propel-gp, giving it a map of arguments.

error-function

(error-function argmap data individual)
Finds the behaviors and errors of an individual: Error is 0 if the value and
the program's selected behavior match, or 1 if they differ, or 1000000 if no
behavior is produced. The behavior is here defined as the final top item on
the INTEGER stack.

instructions

stack-specific instructions, input instructions, close, and constants

random-int

(random-int)
Random integer between -100 and 100 (from smallest)
