the graphical technique for nonlinear circuits was described that enable us to optimize circuits to obtain maximum output power, maximum efficiency or minimum intermodulation. according to this method a high power amplifier in the ka band was designed. using a nonlinear model of the transistor, optimum slope for load-line was determined so that maximum power at the output was obtainable, then ...

Optimal distribution substation placement is one of the major components of optimal distribution system planning projects. In this paper optimal substation placement problem is solved using Imperialist Competitive Algorithm (ICA) as a new developed heuristic optimization algorithm. This procedure gives the optimal size, site and installation time of medium voltage substation, using their relate...

Graphical Models bring together two different mathematical areas: graph theory and probability theory. Recent years have witnessed an increase in the significance of the role played by Graphical Models in solving several machine learning problems. Graphical Models can be either directed or undirected. Undirected Graphical Models are also called Bayesian networks. The manual construction of Baye...

We explore the potential of anytime best-first search schemes for combinatorial optimization tasks over graphical models (e.g., MAP/MPE). We show that recent advances in extending best-first search into an anytime scheme have a potential for optimization for graphical models. Importantly, these schemes come with upper bound guarantees and are sometime competitive with known effective anytime br...
