Which of the following problem-solving approaches is a set of guidelines to handle highly variable...

→ Heuristics are informal rules or guidelines used to solve problems when full information is unavailable or when optimal solutions are computationally impractical. They are often used in complex decision-making and AI.

Why the other options are incorrect:

A: Schedule refers to timing, not problem-solving.

B: A plan is a formal structure, not flexible for uncertain conditions.

D: Algorithms are step-by-step procedures for defined problems — not suited for ambiguity.
