In order to convert the resulting string to an executable polynomials, Arun suggested the library Sympy. Sympy even evaluates the algo, producing a simplified version and/or returning ‘0’ if it is not functional. If this works, I will not need to write an evaluator.
New to this version, the code now calls external .csv files for available functions and terminals. At the very bottom of the run, it auto-generates the polynomial.
