Quizplus · Accepted Answer

Strength reduction is the process of replacing a costly operation with a cheaper one. In this scenario, replacing an arithmetic operation with a faster one is an example of strength reduction, which is a possible local optimization. Constant evaluation, eliminating unnecessary operations, and parse tree construction are different types of optimizations that may or may not involve replacing a costly operation with a cheaper one.
