CSD 15-780: Graduate Artificial Intelligence. Instructors: . Zico. . Kolter. and Zack Rubinstein. TA: Vittorio . Perera. 2. Local search algorithms. Sometimes the path to the goal is irrelevant:. 8-queens problem, job-shop scheduling. This lecture topic. Read Chapter 4.1-4.2. Next lecture topic. Read Chapter 5. (Please read lecture topic material before and after each lecture on that . topic. ). You will be expected to know. Local Search Algorithms. Most local search algorithms are based on derivatives to guide the search.. For differentiable function it has been shown that even if you need to calculate derivatives by finite differences, derivative-based algorithms are better than ones that do not use derivatives.. Sometimes we can handle NP problems with polynomial time algorithms which are guaranteed to return a solution within some specific bound of the optimal solution. within a constant . c. . of the optimal. and. Continuous Search. Local search algorithms. In many optimization problems, the . path . to the goal is irrelevant; the goal state itself is the . solution. In such cases, we can use . local search algorithms. Undergraduate Events . More . details . @ . https://my.cs.ubc.ca/students/development/events. Ericsson Info Session. Mon., Oct . 6, 5:30 . – 7 pm.
