Bidirectional Lao* Algorithm (A Faster Approach To Solve Goal-Directed Mdps), Venkata Deepti Kiran Bhuma
Bidirectional Lao* Algorithm (A Faster Approach To Solve Goal-Directed Mdps), Venkata Deepti Kiran Bhuma
University of Kentucky Master's Theses
Uncertainty is a feature of many AI applications. While there are polynomial-time algorithms for planning in stochastic systems, planning is still slow, in part because most algorithms plan for all eventualities. Algorithms such as LAO* are able to find good or optimal policies more quickly when the starting state of the system is known.
In this thesis we present an extension to LAO*, called BLAO*. BLAO* is an extension of the LAO* algorithm to a bidirectional search. We show that BLAO* finds optimal or E-optimal solutions for goal-directed MDPs without necessarily evaluating the entire state space. BLAO* …

A Service-Based Architecture For Learning Management Systems Which Supports Personalisation And Collaboration, Markus Schmid
Theses
This work develops a service-based architecture for an extensible and customisable learning management system (LMS) runtime environment. The architecture mainly defines interfaces for the interaction of functional system components represented by loosely coupled distributed services. Services that represent functional components of the distributed LMS are called e-leaming services. In addition, underlying infrastructure services provide supportive functionality such as service-lookup within an institution. Users access the system using an LMS portal component that acts as a front-end for the LMS services.
While existing e-leaming environments provide a relatively good coverage of most of the functional requirements defined in this work, they …
