Primary fields of research

·2016/03–2017/03 Research of Personalized Travel Route Planning based on POI-Spatial Network.

Implement a system combining social hot spot data (POIs) and spatial data in Nanjing city to do personalized travel trip recommendations.

·2015/09–2015/12 Research of Personalized Travel Itinerary Planning based on Multi-objective Optimization Algorithm under Multi-Constraints.

Propose a personalized travel route planning problem (PTRP) that is directly interpreted as a multi-objective problem under multi-constraints. An evolution strategy of non-dominated sorting ranking and Tabu search is proposed to handle the optimization of PTRP.
