L-RPG: Introducing a Lifted Forward-Chaining Planner

E-mail Print PDF

L-RPG is a domain-independent Forward-Chaining planner which - unlike many other planners - does not rely on grounding for guiding its search through the search space. The ultimate aim of this planner is to be more scalable than planners which rely on grounding and solve bigger problem instances which cannot currently be solved by state-of-the-art planners due to memory constraints.

Bridging the Gap

E-mail Print PDF

Two pilot studies involving AI planning have been funded through the Interdisciplinary Informatics - Bridging the Gaps programme, working with researchers in Neuroimaging and Robotics.  The projects explore the use of planning in novel application areas, continuing the group's recent work on planning for problems with time and numeric resources.

OPTIC: Optimising Preferences and Time-Dependent Costs

E-mail Print PDF

OPTIC is a temporal planner for use in problems where plan cost is determined by preferences or time-dependent goal-collection costs.  Such problems arise in a range of interesting situations, from scheduling the delivery of perishable goods, to coordinating order-fulfillment activities in warehouses.

Plan-Based Policy-Learning for Surveillance Problems (M. Fox, D. Long, A. Coles, and S. Bernardini)

E-mail Print PDF

An RQ-7B UAB.  Image public domain, from http://en.wikipedia.org/wiki/File:RQ-7B_UAV.jpgThe group has successfully secured ESPRC funds (EP/J012157/1, fEC value £458,818) to research the use of planning to underpin policy learning for surveillance problems.  Surveillance problems give rise to many challenges including the management of uncertainty in an unpredictable environment, the management of restricted resources and the communication of commitments and requests between multiple heterogeneous agent 'observers'. At the heart of surveillance problems lies the need to plan complex sequences of behaviour that achieve surveillance goals. These goals are typically expressed in terms of gathering as much information as possible given constraints, and communicating findings to a human operator.
