    • Hierarchical Goal Network Planning: Initial Results 

      Shivashankar, Vikas; Kuter, Ugur; Nau, Dana (2011-05-31)
      In applications of HTN planning, repeated problems have arisen from the lack of correspondence between HTN tasks and classical-planning goals. We describe these problems and provide a new Hierarchical Goal Network (HGN) ...
    • HTN Planning in Answer Set Programming 

      Dix, Jurgen; Kuter, Ugur; Nau, Dana S. (2002-05-22)
      In this paper we introduce a formalism for solving Hierarchical Task NEtwork (HTN) Planning using Answer Set Programming (ASP). The ASP paradigm evolved out of the stable semantics for logic programs in recent years ...
    • HTN Planning in Answer Set Programming 

      Dix, Jürgen; Kuter, Ugur; Nau, Dana (UMIACS, University of Maryland, 2002-05-22)
      In this paper we introduce a formalism for solving Hierarchical Task NEtwork (HTN) Planning using Answer Set Programming (ASP). The ASP paradigm evolved out of the stable semantics for logic programs in recent years and ...
    • Interactive Planning under Uncertainty with Causal Modeling and Analysis 

      Kuter, Ugur; Nau, Dana; Lemmer, John F. (2003-01-21)
      This paper describes a new technique for interactive planning under conditions of uncertainty. Our approach is based on the use of the Air Force Research Laboratory's Causal Analysis Tool (CAT), a system for creating ...
    • Learning and Verification of Safety Parameters for Airspace Deconfliction 

      Rebguns, Antons; Green, Derek; Levine, Geoffrey; Kuter, Ugur; Spears, Diana (2009-11-30)
      We present a Bayesian approach to learning flexible safety constraints and subsequently verifying whether plans satisfy these constraints. Our approach, called the Safety Constraint Learner/Checker (SCLC), is embedded ...
    • Planning Under Uncertainty: Moving Forward 

      Kuter, Ugur (2006-07-24)
      Reasoning about uncertainty is an essential component of many real-world planning problems, such as robotic and space applications, military operations planning, air and ground traffic control, and manufacturing systems. ...
