### -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
