(ACM Press, 1999)
In many applications, mobile agents are used by a client to delegate a task. This task is usually performed by the agent on behalf of the client, by visiting various service provider's sites distributed over a network. ...
Cheap Newton steps for optimal control problems: automatic differentiation and Pantoja's algorithm
(1999)
In this paper we discuss Pantoja's construction of the Newton direction for discrete time optimal control problems. We show that automatic differentiation (AD) techniques can be used to calculate the Newton direction ...
Delegation and not-so smart cards
(1999)
We consider three aspects of delegation: What kinds of binding are required between real world artifacts and bit patterns? What are the atomic elements of a security policy and in what ways must they fit together? What are ...
Merkle puzzles revisited - finding matching elements between lists
(University of Hertfordshire, 1999)
Consider the following problem. A and B have a N-element set of bit-strings. They wish to find all collisions, in other words to find the common strings of their sets or to establish that there are none. How much data must ...
