WebThis course covers basic algorithm design techniques such as divide and conquer, dynamic programming, and greedy algorithms. It concludes with a brief introduction to intractability (NP-completeness) and using linear/integer programming solvers for solving optimization problems. We will also cover some advanced topics in data structures. WebClaim: We can solve this using a greedy algorithm. A greedy algorithm is a myopic algorithm that processes the input one piece at a time with no apparent look ahead. Greedy Interval Scheduling. 1. Use a simple rule to select a request i. 2. Reject all requests incompatible with i. 3. Repeat until all requests are processed. 2 6.046J high waisted pants butts
