3D Field D: Improved Path Planning and Replanning in Three Dimensions
— We present an interpolation-based planning and replanning algorithm that is able to produce direct, lowcost paths through three-dimensional environments. Our algorithm builds u...

Rate-based query optimization for streaming information sources
Relational query optimizers have traditionally relied upon table cardinalities when estimating the cost of the query plans they consider. While this approach has been and continue...
