Agent supervision is a form of control/customization where a supervisor restricts the behavior of an agent to enforce certain requirements, while leaving the agent as much autonomy as possible. This is done in a setting based on the situation calculus and a variant of the ConGolog programming language that is situation-determined, i.e., the remaining program is a function of the action performe...
This paper introduces GLAM, a system based on situation calculus and meta-rules, which is able to provide adaptation by means of selection of actions. It is primarily designed to provide adaptive navigation. The different levels of conception, related to different aspects of the available metadata, are split in different layers in GLAM, in order to ease the conception of the adaptation system a...
We present first ideas on how results about qualitative spatial reasoning can be exploited in reasoning about action and change. Current work concentrates on a line segment based calculus, the dipole calculus and necessary extensions for representing navigational concepts like turn right. We investigate how its conceptual neighborhood structure can be applied in the situation calculus for reaso...
A promising technique used in some planning systems to improve their performance is the use of domain dependent search control knowledge. We present a procedure for compiling search control knowledge, expressed declaratively in a logic, into the preconditions of the plan actions (operators). We do this within the framework of the situation calculus by introducing a transformation of nonMarkovia...
Reasoning about perception of depth and about spatial relations between moving physical objects is a challenging problem. We investigate the representation of depth and motion by means of depth profiles whereby each object in the world is represented as a single peak. We propose a logical theory, formulated in the situation calculus (SC), that is used for reasoning about object motion (includin...
By using an example from a robot navigating domain, we argue that to specify declaratively the behavior of an agent, we need to have a formal and explicit notion of \quality plans." To that end, we propose the following three domain independent measures of plan quality: a plan is said to be A-minimalif none of the actions in it can be deleted and have it continue to be a plan; it is said to be ...
We present a declarative formalization of STRIPS [1] as a reasoning strategy in the situation calculus [10]. The idea is to use logic not only to represent planning problems, but also to describe the mental situations, mental actions and reasoning strategy STRIPS uses to solve those problems.
In this paper we study the diierences between two logic theories for temporal reasoning, the Situation Calculus and the Event Calculus, and the implications of these diierences. We construct a new formalism that combines the advantages of both Situation and Event Calculus and avoids the problems of either. The new formalism is useful for general temporal reasoning in worlds with discrete and co...
