Mason, James C; Branch, Andrew; Xu, Guangyu; Jakuba, Michael V.; German, Christopher R.; Chien, Steve; Bowen, Andrew D.; Hand, Kevin P.; Seewald, Jeffrey S., 2020, "Evaluation of AUV Search Strategies for the Localization of Hydrothermal Venting", https://hdl.handle.net/2014/53084, 30th International Conference on Automated Planning and Scheduling (ICAPS 2020), Nancy, France, October 26-30, 2020, JPL Open Repository
Ocean Worlds represent one of the best chances for the dis- covery of extra-terrestrial life within our own solar system, particularly near sources of hydrothermal venting. To study the oceans on Ocean Worlds will require a new type of mis- sion to penetrate the icy shell, deploy... |

Branch, Andrew; Mason, James; Chien, Steve, 2020, "Golden Section Search for Single Beacon Homing", https://hdl.handle.net/2014/53082, 30th International Conference on Automated Planning and Scheduling (ICAPS 2020), Nancy, France, October 26-30, 2020, JPL Open Repository
Exploration of Ocean Worlds requires a new type of mission to be developed, an ice penetrating submersible vehicle. Such a mission would present a number of new challenges, including long range autonomous under ice navigation. We have developed a method based on Golden Section Se... |

Agrawal, Jagriti; Yelamanchili, Amruta; Chien, Steve, 2020, "Using Explainable Scheduling for the Mars 2020 Rover Mission", https://hdl.handle.net/2014/53307, 30th International Conference on Automated Planning and Scheduling (ICAPS 2020), Nancy, France, October 26-30, 2020, JPL Open Repository
Understanding the reasoning behind the behavior of an auto- mated scheduling system is essential to ensure that it will be trusted and consequently used to its full capabilities in critical applications. In cases where a scheduler schedules activities in an invalid location, it i... |

Maillard, Adrien H; Chien, Steve; Wells, Christopher, 2020, "Scheduling the Mapping of a planet under geometrical constraints", https://hdl.handle.net/2014/53295, VIRTUAL The International Symposium on Artificial Intelligence, Robotics and Automation in Space (i-SAIRAS) 2020, Pasadena, California, October 19-23, 2020, JPL Open Repository
Scheduling the coverage of a planet by scientific instruments on board spacecrafts under observational constraints is central in a significant number of current and future missions for the exploration of the solar system. In this paper, we describe the components and algorithms o... |

Stegun Vaquero, Tiago; Chien, Steve; Agrawal, Jagriti, 2020, "Constraint-based Brittleness Analysis of Task Networks for Planetary Rovers", https://hdl.handle.net/2014/53292, VIRTUAL The International Symposium on Artificial Intelligence, Robotics and Automation in Space (i-SAIRAS) 2020, Pasadena, California, October 19-23, 2020, JPL Open Repository
We propose a new method to analyze brittleness of task networks with respect to not only temporal but any arbitrary set of constraints. The method allows the detection and enumeration of activities that, with modest duration variation, violate the target constraints. |

Saint-Guillain, Michael; Vaquero, Tiago; Agrawal, Jagriti; Chien, Steve, 2020, "Robustness Computation of Dynamic Controllability in Probabilistic Temporal Networks with Ordinary Distributions", https://hdl.handle.net/2014/52335, 29th International Joint Conference on Artificial Intelligence, Yokohama, Japan, July 11-17, 2020, JPL Open Repository
Most existing works in Probabilistic Simple Temporal Networks (PSTNs) base their frameworks on well-defined probability distributions. This paper addresses on PSTN Dynamic Controllability (DC) robustness measure, i.e. the execution success probability of a network under dynamic c... |
