Keyword-aware Optimal Route Search
Summary: Introduces keyword-aware optimal route (KOR) search: find a budget-feasible route covering specified POI keywords while optimizing a route score, an NP-hard generalization beyond standard route planning. Provides bounded OSScaling, faster BucketBound, and greedy approximations with empirical efficiency/accuracy evaluation. (summarized by gpt-5.6-luna on Jul 24 2026)
