Analyzing Reachability within Plan Space
We present a new structure developed to analyze reachability within the plan space. The main goal is to propose a new heuristic estimator to guide the search in partial order planners. It could be used to evaluate establishers of open-conditions as well as resolvents for threats or resource contention. Algorithms are detailed to expand this structure and update it along the search.
متن کاملPlan-space vs. State-space Planning in Reuse and Replay
The aim of case-based planning (CBP) is to improve the e ciency of plan generation by taking advantage of previous problem-solving experience. This paper explores the relative utility of placing CBP within plan-space vs. state-space planning. We argue that it is in the ability to adapt the previous case to the new situation that plan-space planning proves to be more e cient. To be able to exten...
متن کاملPlan-Refinement Strategies and Search-Space Size
During the planning process, a planner may have many options for refinements to perform on the plan being developed. The planner’s efficiency depends on how it chooses which refinement to do next. Recent studies have shown that several versions of the popular “least commitment” plan refinement strategy are often outperformed by a fewest alternatives first (FAF) strategy that chooses to refine t...
متن کاملAn Issue in Goal Addition in Continuous Robotic Plan Execution
Robotic plan execution has traditionally assumed that goals are articulated prior to mission execution. As robots have become persistent and increasingly moved into real-world environments, this assumption is not necessarily true; for instance a user can decide to give a new objective to the robot for inclusion in the plan being formulated, add newer goals, or modify others queued for execution...
متن کاملSpecial Issue—Bathymetry from Space
considered to be a solved problem in oceanography. The general physics of tides were understood, and they could be modeled with reasonable fidelity using relatively simple differential equations solved on computers. In general, it was thought that improvements in tide models would be made only by having higherresolution models run on faster computers. The advent of satellite altimetry by GEOSAT...
