-OPERATORS TESTED with Karoo GP v1.4
+This file contains all operators supported by Karoo GP as of v1.0.
 
+Note that some operators are simply entered along with the arity (total number of elements anticipated), while others 
+must be preceded by another operator due the manner in which Karoo flattens the trees into a mathematical expression. 
+Else, Karoo will attempt a function such as (a)sin(b) where sin(b) is correct, but (a)sin requires an operator between 
+the operand 'a' and the operator 'sin'. This will be addressed in a future update to Karoo. 
+
+To apply one or more operator to a given run, copy/paste the desired operators from the USE IN KAROO table(s) below, 
+into the associated file for Classification (files/operators_CLASSIFY.csv) or Regression (files/operators_REGRESS.csv)
