ion it ranges between PVM-Prolog which is a pure paradigm extendedby message passing and a high-level multi-agent language such as vivid agents.7.3 ICEICE [Amt95, AB96] de nes a model to support distributed AI applications overhybrid languages and heterogeneous, distributed platforms. It is available fromProlog, Lisp, C, C++ and Tcl/Tk and is, similar to PVM-Prolog, implemen...

We call a garbage collector conservative if it has only partial information about the location of pointers and is thus forced to treat arbitrary bit patterns as though they might be pointers in at least some cases We show that some very inexpensive but previously unused tech niques can have dramatic impact on the e ectiveness of conservative garbage collectors in reclaiming mem ory Our most sig...

In optical networks the vast bandwidth available in an optical bre may be utilized by splitting it into several channels each of a di erent wavelength This allows signals to be routed entirely in the optical domain This es say studies such routings and examines the number of di erent wavelengths needed for irregular networks We nd the number of wavelengths needed in large random networks in ter...

We formulate the call admission control problem for a single link in an integrated service environment as a Markov Decision Problem In prin ciple an optimal admission control policy can be computed using methods of Dynamic Programming However as the number of possible states of the un derlying Markov Chain grows exponentially in the number of customer classes Dynamic Programming algorithms for ...

information about the variables of one clause but during the concrete computation the accumulated constraints may contain nonlinear parts from arbitrary clauses. Since we are interested in the analysis of all nonlinear constraints, we will show in Theorem 3 that the nonlinear constraints with variables outside dom(A) are also covered by the abstraction A. Since our abstract interpretation algor...
