INTRODUCTION In recent years Distributed Constraint Optimization (DCOP) [2] has received considerable attention as a powerful paradigm for multiagent coordination. Example applications include target tracking in distributed sensor networks [7] and dis- tributed event scheduling [1]. Permission to make ...
The semi-Markov reliability model of a system operation is constructed. For the model the gain optimization problem subject to availability constraint is formulated and solved. An example illustrating the theoretical results is presented in the work.Franciszek Grabski...
Another example occurs in production scheduling. Jobs are to be processed on machines that can handle only one job at a time, so that each job is completed by a given deadline. Further examples arise from the observation that an optimization problem can be expressed as a sequence of CSPs....
For example, Lagrange multiplier for the constraint x/y − 10 ≤ 0 (y < 0) is different for the same constraint expressed as x − 10y≤ 0, or 0.1x/y − 1 ≤ 0. The optimum solution for the problem does not change by changing the form of the constraint, but its Lagrange ...
a, The process of formulating a problem into the DRNets framework. (i) We start by formulating tasks as data-driven constrained optimization problems, with discrete and continuous variables. For example, the data-driven constrained optimization task in MNIST-Sudoku is to demix images of two overl...
with the real world is to decompose it into many sub-problems Example: Australia map-coloring T is not connected to the mainland The coloring of T and that of the mainland are independent sub-problems Any solution for the mainland combined with any solution for T yields a solution for the ...
The VNF placing constraints largely depend on their work patterns, e.g., the conversion, mobile, security, optimization, and other strategic functions. For example, gateways are placed at the boundary between two networks to convert protocols and forward traffic. The firewalls should be placed at...
For example, Zeballos and Henning, 2003, Kotecha et al., 2007, Felizari et al., 2009 discuss the modeling aspects of the multistage batch scheduling problem where each product has to be sequentially processed in a number of stages, and each stage contains one or more parallel processing ...
