This document discusses analyzing the time efficiency of recursive algorithms. It provides a general 5-step plan: 1) choose a parameter for input size, 2) identify the basic operation, 3) check if operation count varies, 4) set up a recurrence relation, 5) solve the relation to determine growth order. It then gives two examples - computing factorial recursively and solving the Tower of Hanoi puzzle recursively - to demonstrate applying the plan. The document also briefly discusses algorithm visualization using static or dynamic images to convey information about an algorithm's operations and performance.
