ArXiv 2023 survey paper categorizing ANN algorithms (hash/tree/graph/quantization) for vector databases, covering architecture, storage, retrieval, and LLM integration. Details benchmarks reviewed and accuracy-scalability trade-offs. Suited for academic/research use in ANN method selection; contrasts 2023 algorithmic depth with prior system surveys and 2026 benchmarks.
