Branch and bound

Branch and bound. branch and bound methods economize the search for the best trees by backing out of dead alleys. The Traveling Salesman Problem. the technique can be used to solve the traveling salesman problem. The Traveling Salesman Problem. an arbitrary route. d=5.4342.

Branch and Bound Example

Branch and Bound Example. Initial lower bound. Use 1 machine preemptive schedule as lower bound Job 2 has a lateness of 5, this is a lower bound on Lmax. J1. J3. J4. J3. J2. 10. 5. 4. 17. 15. Initial upper bound. Find some schedule. Lmax is 7. J3. J4. J1. J2. 12. 6. 4. 17.

Branch and Bound

Branch and Bound. Similar to backtracking in generating a search tree and looking for one or more solutions Different in that the “objective” is constrained to maximization or minimization of a given function We will consider minimization problems in this section.
