Network Optimization with Concave Costs
In this paper the problem of minimum cost communication network design is considered where the costs are piecewise linear concave. Several methods are compared: Simulated Annealing method, a heuristic based on the method proposed by Minoux, and a lagrangian method based on lower bounding procedure.

متن کاملDistributional Similarity of Words with Different Frequencies
Distributional semantics tries to characterize the meaning of words by the contexts in which they occur. Similarity of words hence can be derived from the similarity of contexts. Contexts of a word are usually vectors of words appearing near to that word in a corpus. It was observed in previous research that similarity measures for the context vectors of two words depend on the frequency of the...
متن کاملAdaptive Network Flow with k-Arc Destruction
When a flow is not allowed to be reoriented the Maximum Residual Flow Problem with k-Arc Destruction is known to be NP -hard for k = 2. We show that when a flow is allowed to be adaptive the problem becomes polynomial for every fixed k.
متن کاملPeriodic and Guiding Structures at Microwave Frequencies
The paper reviews the properties of periodic and guiding structures which now play an important part in the operation of components, antennas, electron tubes and low-noise amplifiers. An account is first given of dispersive propagation in periodic-loaded lines, showing how the frequency characteristic breaks into pass and stop bands. The formation of forwardand backward-space harmonics and the ...
