The chapter focuses on memoization and dynamic programming as strategies to optimize recursive function evaluations, specifically addressing the inefficiencies in recursive calculations of the Fibonacci sequence. It emphasizes the importance of not recalculating values by storing previously computed results in a table. This ultimately leads to more efficient calculations, transforming recursive methods into iterative processes that utilize dynamic programming principles.

What we have learnt
- Memoization allows for storing computed values to avoid redundant calculations.
- Dynamic programming provides a systematic approach to solving problems by tackling dependencies iteratively.
- Efficiency in computing recursive sequences can significantly improve performance through careful management of subproblem evaluations.
Key Concepts
-
Term: Memoization
Definition: A technique where previously computed results are stored to avoid recalculating them during recursive function calls.
-
Term: Dynamic Programming
Definition: An optimization strategy that eliminates the need for recursive calls by filling in a table of results iteratively based on dependency order.
-
Term: Inductive Definition
Definition: A way of defining functions or sequences where the base case is established and subsequent values are defined in terms of previous ones.
-
Term: Fibonacci Sequence
Definition: A series of numbers where each number is the sum of the two preceding ones, commonly used to illustrate recursive computations.
