Analytic and locally approximate solutions to properties of probabilistic processes
[chapter]
1995
Lecture Notes in Computer Science
Preserved Fulltext
We present how analytic formulae for performance properties can be derived from probabilistic process algebraic descriptions; demonstrating how local approximate solutions can be derived for the properties ...
Recent extensions to process algebra can be used to describe performance or error rate properties of systems. We examine how properties of systems expressed in these algebras can be elicited. ...
The generation of local approximations to the solutions of systems is of great importance. ...

This probabilistic formulation of classic methods is valuable in two ways: analytically, it highlights implicit prior assumptions favoring certain approximate solutions to the IVP over others, and gives ...
We describe a class of algorithms that formulate the solution to an IVP as inference on a latent path that is a draw from a Gaussian process probability measure (or equivalently, the solution of a linear ...

Two static policies are considered: probabilistic assignment and allocation according to a fixed pattern. For these two policies, general properties as well as optimization aspects are discussed. ...
We consider the traffic allocation problem: arriving customers have to be assigned to one of a group of servers. ...
Due to this property, there is only one local minimum, which consequently has to be the optimal solution for the allocation problem. ...
