"The presence of uncertainty in a process description has consistently been a severe factor on top of things. relocating on from prior stochastic and strong regulate paradigms, the most target of this booklet is to introduce the reader to the basics of probabilistic equipment within the research and layout of doubtful platforms. utilizing so-called randomized algorithms, this rising zone of analysis promises a discount within the computational complexity of classical powerful keep an eye on algorithms and within the conservativeness of tools like H[subscript [infinity]] control."--Jacket. learn more...
