Checks that a hydrophobic/polar sequence follows a self-avoiding unit-step lattice path, then counts non-consecutive hydrophobic contacts and assigns one negative energy unit per contact. It evaluates a supplied toy conformation only; it neither predicts a fold nor represents atomic chemistry, kinetics, solvent or biological function.
