A General Selection Criterion For Inductive Inference
This paper presents a general criterion for measuring the degree to which any given theory can be considered a good explanation of a particular body of data. A formal definition…

Synchronization Of Multiagent Plans Using A Temporal Logic Theorem Prover
Following an approach suggested by Georgeff, this paper considers the use of synchronizing primitives to resolve conflicts and produce a plan that is as unrestrictive as possible. In a sense,…

The Structures Of Discourse Structure
This paper presents the basic elements of a computational theory of discourse structure that simplifies and expands upon previous work. It is concerned with answers to two rather simple questions:…

One-Eyed Stereo: A Unified Strategy To Recover Shape From A Single Image
In this paper we contend that the distinct assumptions made in each of these schemes must be tantamount to providing a second (virtual) image of the original scene, and that…

Behavioral Specification and Planning for Multiagent Domains
This report discusses a new approach to the specification of properties of multiagent environment and the generation of plans for such domains.

Experimental Robot Psychology
Here I propose an approach that I call it experimental robot psychology because it involves formalizing and reasoning about the design of existing robot agents. It shows promise of yielding…

Linear Precedence In Discontinuous Constituents: Complex Fronting In German
It is shown that the current framework of Generalized Phrase Structure Grammar (GPSG) is not suited for describing the interaction of leftward extractions, scrambling, and constraints on linear order.

Reference and Denotation: The Descriptive Model
This paper deals with a specific approach to the problem of reference that I call the descriptive model. In particular, I am going to examine some relations between this model…

On Some Formal Properties Of Metarules
Grammars contain rules for generating sentences. Metarules are statements about these rules. They are metagrammatical devices that can be used to generate rules of the grammar or to encode certain…
