### -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 BOOLEAN stack.

### instructions
