The alpha constant is for the local optimality T-Test threshold. Before we used epsilon for the T-Test threshold, but the epsilon constant is meant to be used for the stretch test(s) only. This changeset fixes the local optimality T-Test and uses the epsilon constant for the two stretch tests: - We test the stretch for the total route against epsilon and - We test the detour against the epsilon now, too We can discuss if the second stretch test should actually use epsilon, too, or a adapted value of it - but definitly not alpha.
