The syntax of the language, PDDL2.1, is described, which has considerable modelling power -- exceeding the capabilities of current planning technology -- and presents a number of important challenges to the research community.Expand
The paper addresses the questions of comparative performance between planners, comparative difficulty of domains, the degree of agreement between planners about the relative difficulty of individual problem instances and the question of how well planners scale relative to one another over increasingly difficult problems through statistical analysis of the raw results.Expand
This paper explores the potential of a forward-chaining state-based search strategy to support partial-order planning in the solution of temporal-numeric problems, and compares POPF with the approach of constructing a sequenced plan and lifting a partial order from it.Expand
We propose an extension to the PDDL language, called PDDL3.0, that aims at a better characterization of plan quality by allowing the user to express strong and soft constraints about the structure of… Expand
The results indicate significant progress in the field, but they also reveal that some important issues remain open and require further research, such as dealing with strong constraints and computing high quality plans in metric-time domains and domains involving soft goals or constraints.Expand
The ROSPLAN framework is described, an architecture for embedding task planning into ROS systems and a case study in autonomous robotics is provided, involving autonomous underwater vehicles in scenarios that demonstrate the flexibility and robustness of the approach.Expand
The syntax and modelling style of PDDL+, a planning domain description language for modelling mixed discrete-continuous planning domains, is described, showing that the language makes convenient the modelling of complex time-dependent effects.Expand
This work presents arguments to support the claim that plan stability is a valuable property, and proposes an implementation, based on LPG, of a plan repair strategy that adapts a plan to its new context.Expand
The plan validation tool, VAL, has been extended to include advanced features of PDDL2.1 which have proved important in mixed-initiative planning in a space operations project.Expand
A process by which state invariants can be extracted from the automatically inferred type structure of a domain is described, being developed for exploitation by STAN, a Graphplan based planner that employs state analysis techniques to enhance its performance.Expand
