ODD-based Query-time Scenario Mutation Framework for Autonomous Driving Scenario databases

Yun Tang, Dhanush Raj, Xingyu Zhao, Xizhe Zhang, Antonio A. Bruto da Costa, Siddartha Khastgir +1

ICRA 2024poster

Large-scale scenario databases may contain hundreds of thousands of scenarios for the verification and validation (V&V) of autonomous vehicles (AV). Scenarios in the database are often labelled with semantic Operational Design Domain (ODD) tags (e.g., WeatherRainy, RoadTypeHighway and ActorTypeTruck…

Early and Efficient Identification of Useless Constraint Propagation for Alldifferent Constraints

Xizhe Zhang, Jian Gao, Yizhi Lv, Weixiong Zhang

IJCAI 2020poster

Constraints propagation and backtracking are two basic techniques for solving constraint satisfaction problems (CSPs). During the search for a solution, the variable and value pairs that do not belong to any solution can be discarded by constraint propagation to ensure generalized arc consistency so…
