Question
Consider a Local Search procedure such as Random Hill Climbing which employs the 2-change modification as neighbourhood function and the following instance of the Travelling Salesman Problem: 10 During the execution of the search, the highlighted (in bold) tour is visited. This current tour has a length of (62): [A → C → B → E → D → A] Select ALL correct statements. D a. The 2-change modification neighbourhood for TSP is reversible. O b. None of the statements is correct. O c. The modification, REMOVE ((A, C), (B, E)) and ADD ((A, B), (C, E)), is not a valid 2-change modification. O d. The current tour is a local minimum. O e. REMOVE ((A, D), (B, E)) and ADD ((A, B), (D, E)) is a valid 2-change modification, but not accepted for the next iteration step. O f. The modification, REMOVE ((A, D), (C, B)) and ADD ((C, D), (A, B)), yields in a tour which is accepted for the next iteration step. g. [A → C → B → E → D → A] is a neighbour of the tour [A → E → D → B → C → A] O h. The modification, REMOVE ((A, C), (A, D)) and ADD ((C, D), (A, A)), is a valid 2-change modification.
