NeuSO: Neural Optimizer for Subgraph Queries

Summary: Fixes poor heuristic vertex-orderings for subgraph enumeration with NeuSO, a learned optimizer for heterogeneous, schema-flexible graphs. It uses a compact query-graph encoder, multi-task cardinality+cost estimation, and a top-down enumerator to produce faster, higher-quality plans. (summarized by gpt-5-mini on Feb 11 2026)
