Learn some methods for attacking and solving recurrence equations.
• How do you solve recurrence equations?
• How do you use a divide and conquer algorithm to split a problem into two halves?
• What are some method for solving recurrence equations?
• How can you use repeated substitution to solve recurrence equations?
• What is the Master Theorem for solving divide and conquer recurrence equations, and how is it used instead of repeated substitution to analyze complexity more simply?
• How is change of variables used to solve recurrence equations?
• How can guessing the time complexity and proving by induction be used to solve recurrence equations?
• What are linear homogeneous equations and how can they be used to solve recurrence equations?
• How can you use Linear Algebra and diagonalization to solve recurrence equations?
• How do you find order, magnitude, or time complexity of sorts and other algorithms?
This lecture focuses on solving recurrence equations using a variety of different methods. The different methods and an explanation of how to use them and when they are useful are explained with a variety of problems in this lesson. Some really great example problems are done to solidify understanding of these concepts. For the most part, however, this video gets bogged down with a lot of really in-depth calculations.
