Greedy scheduling algorithm . induction
WebGreedy algorithms, divide and conquer, dynamic programming. Discuss principles that can solve a variety of problem types. Design an algorithm, prove its correctness, analyse its … 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.
