WebApr 27, 2024 · A general optimization problem can be defined by specifying a set of constraints that defines a subset in some underlying space (like the Euclidean space) called the feasible subset and an objective function that we are trying to maximize or minimize, as the case may be, over the feasible set. 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.

WebMore generally, we design greedy algorithms according to the following sequence of steps: o Cast the optimization problem as one in which we make a choice and are left with one subproblem to solve. o Prove that there is always an optimal solution to the original problem that makes the greedy choice, so that the greedy choice is always safe. WebGreedy Algorithms For many optimization problems, using dynamic programming to make choices is overkill. Sometimes, the correct choice is the one that appears “best” at the moment. Greedy algorithms make these locally best choices in the hope (or knowledge) that this will lead to a globally optimum solution.
