A survey paper classifies existing approaches to a research problem using well-defined criteria. The paper builds a framework around an existing topic without contributing new research. It exposes areas needing further study, compiles current knowledge, and provides context for new researchers. Authors should select emerging topics with new algorithms and no existing surveys. They should read 20-40 relevant papers to develop a strong understanding before writing in a structured format that includes an introduction, classification approach, example explanations, trends analysis, and conclusion.
