Abstract

In this paper, we would like to present Grounded (Lifted) Linearizer, a hierarchical task network (HTN) planning system which won the Partial Order (PO) Agile and Satisficing tracks of the International Planning Competition 2023 on Hierarchical Task Network (HTN) Planning. This system consists of two parts. The first part is a preprocessor developed in house which transforms a POHTN problem into a total order (TO) one and which is the main contribution of this paper. The second part is an existing HTN planner. The outstanding performance of our assembled planning system thus serves as an evidence for how our preprocessor can enhance the efficiency of other existing planners.
