Book excerpt: Network optimization problems arise naturally as a way of encoding the coordination task entrusted to multi-agent systems deployed in many areas of engineering, including power, communication, transportation, and swarm robotics. The large-scale nature of these systems coupled with the intrinsic modularity in their structure due to the technological advances in communication, embedded computing, and parallel processing requires a shift from the traditional paradigm of centralized decision-making to a distributed one. This transition, which is essential to harness the true capabilities of modern cyberphysical systems, raises a number of noteworthy challenges as well as opportunities, and has sparked the development of solutions that scale with the number of agents, provide plug-and-play capabilities, and are resilient against single points of failure. Motivated by these considerations, this thesis is a contribution to the growing body of work that deals with the synthesis and analysis of provably correct algorithmic solutions to structured network problems. Specifically, the thesis is divided into two parts. The first part focuses on synthesizing algorithmic solutions for application-agnostic large-scale network problems. We consider constrained optimization problems where the global objective function is the aggregate of local objectives of the participating agents; the collective goal of the agents and the underlying interaction pattern among them define the constraints. Using continuously differentiable exact penalty functions and globally projected dynamical systems, we then propose privacy-preserving, scalable, accelerated and anytime algorithms to solve these optimization problems. The second part is application-oriented and deals with constrained optimization problems in the context of power systems. In particular, we focus on the utilization of distributed energy resources for frequency regulation in the modern grid. We design distributed time-invariant controllers stabilizing the time-varying power dynamics for primary frequency control, and develop meaningful abstractions for groups of distributed energy resources to participate in the secondary frequency control market.

Book Synopsis Constrained Shortest Paths and Related Problems by : Mark Ziegelmann
Download or read book Constrained Shortest Paths and Related Problems written by Mark Ziegelmann and published by VDM Publishing. This book was released on 2007-12-01 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The shortest path problem arises in various applied settings where some material (e.g., computer data packet, telephone calls, vehicles) is sent between two specified points in a network as quickly, cheaply or reliably as possible. In practice we want to optimize a combination of those criteria (i.e., we have a bi- or multicriteria shortest path problem). This book proposes a 2-step method for the constrained shortest path problem. A relaxation is solved to get upper and lower bounds and then the gap is closed with clever path ranking to obtain the exact solution. Different old and new methods are compared both theoretically and experimentally. The proposed 2-step method also works for a more general class of constrained network optimization problems. In addition the generic approach is illustrated with several examples and a newly developed Constrained Network Optimization Software Package (CNOP) is introduced that provides this generic 2-step approach as well as all state of the art algorithms for constrained shortest paths. This book is a valuable resource for researchers, students as well as practitioners working on the constrained shortest path problem and related problems.

Book Synopsis Networks in Action by : Gerard Sierksma
Download or read book Networks in Action written by Gerard Sierksma and published by Springer Science & Business Media. This book was released on 2009-12-11 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most well-known of all network optimization problems is the shortest path problem, where a shortest connection between two locations in a road network is to be found. This problem is the basis of route planners in vehicles and on the Internet. Networks are very common structures; they consist primarily of a ?nite number of locations (points, nodes), together with a number of links (edges, arcs, connections) between the locations. Very often a certain number is attached to the links, expressing the distance or the cost between the end points of that connection. Networks occur in an extremely wide range of applications, among them are: road networks; cable networks; human relations networks; project scheduling networks; production networks; distribution networks; neural networks; networks of atoms in molecules. In all these cases there are “objects” and “relations” between the objects. A n- work optimization problem is actually nothing else than the problem of ?nding a subset of the objects and the relations, such that a certain optimization objective is satis?ed.

Book Synopsis Optimization of Computer Networks by : Pablo Pavón Mariño
Download or read book Optimization of Computer Networks written by Pablo Pavón Mariño and published by John Wiley & Sons. This book was released on 2016-05-02 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the design and optimization of computer networks applying a rigorous optimization methodology, applicable to any network technology. It is organized into two parts. In Part 1 the reader will learn how to model network problems appearing in computer networks as optimization programs, and use optimization theory to give insights on them. Four problem types are addressed systematically – traffic routing, capacity dimensioning, congestion control and topology design. Part 2 targets the design of algorithms that solve network problems like the ones modeled in Part 1. Two main approaches are addressed – gradient-like algorithms inspiring distributed network protocols that dynamically adapt to the network, or cross-layer schemes that coordinate the cooperation among protocols; and those focusing on the design of heuristic algorithms for long term static network design and planning problems. Following a hands-on approach, the reader will have access to a large set of examples in real-life technologies like IP, wireless and optical networks. Implementations of models and algorithms will be available in the open-source Net2Plan tool from which the user will be able to see how the lessons learned take real form in algorithms, and reuse or execute them to obtain numerical solutions. An accompanying link to the author’s own Net2plan software enables readers to produce numerical solutions to a multitude of real-life problems in computer networks (www.net2plan.com).

Book Synopsis Real-time PDE-constrained Optimization by : Lorenz T. Biegler
Download or read book Real-time PDE-constrained Optimization written by Lorenz T. Biegler and published by SIAM. This book was released on 2007-01-01 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many engineering and scientific problems in design, control, and parameter estimation can be formulated as optimization problems that are governed by partial differential equations (PDEs). The complexities of the PDEs--and the requirement for rapid solution--pose significant difficulties. A particularly challenging class of PDE-constrained optimization problems is characterized by the need for real-time solution, i.e., in time scales that are sufficiently rapid to support simulation-based decision making. Real-Time PDE-Constrained Optimization, the first book devoted to real-time optimization for systems governed by PDEs, focuses on new formulations, methods, and algorithms needed to facilitate real-time, PDE-constrained optimization. In addition to presenting state-of-the-art algorithms and formulations, the text illustrates these algorithms with a diverse set of applications that includes problems in the areas of aerodynamics, biology, fluid dynamics, medicine, chemical processes, homeland security, and structural dynamics. Audience: readers who have expertise in simulation and are interested in incorporating optimization into their simulations, who have expertise in numerical optimization and are interested in adapting optimization methods to the class of infinite-dimensional simulation problems, or who have worked in "offline" optimization contexts and are interested in moving to "online" optimization.
Book Synopsis Optimization of Temporal Networks under Uncertainty by : Wolfram Wiesemann
Download or read book Optimization of Temporal Networks under Uncertainty written by Wolfram Wiesemann and published by Springer Science & Business Media. This book was released on 2012-01-04 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many decision problems in Operations Research are defined on temporal networks, that is, workflows of time-consuming tasks whose processing order is constrained by precedence relations. For example, temporal networks are used to model projects, computer applications, digital circuits and production processes. Optimization problems arise in temporal networks when a decision maker wishes to determine a temporal arrangement of the tasks and/or a resource assignment that optimizes some network characteristic (e.g. the time required to complete all tasks). The parameters of these optimization problems (e.g. the task durations) are typically unknown at the time the decision problem arises. This monograph investigates solution techniques for optimization problems in temporal networks that explicitly account for this parameter uncertainty. We study several formulations, each of which requires different information about the uncertain problem parameters.

Book Synopsis Foundations of Network Optimization and Games by : Terry L. Friesz
Download or read book Foundations of Network Optimization and Games written by Terry L. Friesz and published by Springer. This book was released on 2015-09-30 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a book about infrastructure networks that are intrinsically nonlinear. The networks considered range from vehicular networks to electric power networks to data networks. The main point of view taken is that of mathematical programming in concert with finite-dimensional variational inequality theory. The principle modeling perspectives are network optimization, the theory of Nash games, and mathematical programming with equilibrium constraints. Computational methods and novel mathematical formulations are emphasized. Among the numerical methods explored are network simplex, gradient projection, fixed-point, gap function, Lagrangian relaxation, Dantzig-Wolfe decomposition, simplicial decomposition, and computational intelligence algorithms. Many solved example problems are included that range from simple to quite challenging. Theoretical analyses of several models and algorithms, to uncover existence, uniqueness and convergence properties, are undertaken. The book is meant for use in advanced undergraduate as well as doctoral courses taught in civil engineering, industrial engineering, systems engineering, and operations research degree programs. At the same time, the book should be a useful resource for industrial and university researchers engaged in the mathematical modeling and numerical analyses of infrastructure networks.
