Solving Recurrence Functions
In the previous chapter, we discussed the challenges of analyzing recursive algorithms, particularly in estimating their computational complexity. In this chapter, we will explore three primary methods for solving recurrence functions: substitution method, master theorem, and visualization techniques using recursion trees.
The substitution method involves constructing rigorous proofs to solve recurrence functions. This method, while sometimes intricate, is versatile and can handle a wide range of recurrence functions. In the substitution method, we employ various techniques, including mathematical induction, to validate our solutions.
The master theorem, also known as the master method, provides a systematic approach to determining the complexity of a recursive algorithm based on the parameters of its recurrence function. This theorem offers a set of straightforward rules, making it a powerful tool for analyzing many common recurrence functions.
