Segment search for local extremums of images based on the analysis of brightness of adjacent homogeneous areas

Informatika, 2019
The problem of finding local extrema on halftone images is considered. Well-known block-search algorithms provide high speed, but they extract only strict (single-pixel) extremes, skipping extreme areas formed by non-strict extremes. Morphological search

Selected Remarks about Computer Processing in Terms of Flow Control and Statistical Mechanics

Entropy, 2016
Despite the fact that much has been said about processing in computer science, it seems that there is still much to do. A classical approach assumes that the computations done by computers are a kind of mathematical operation (calculations of functions ...

Exploiting bounded signal flow for graph orientation based on cause-effect pairs

Algorithms for Molecular Biology, 2011
Background We consider the following problem: Given an undirected network and a set of sender-receiver pairs, direct all edges such that the maximum number of "signal flows" defined by the pairs can be routed respecting edge directions.

Sum-rate optimization methods and analysis for reconfigurable intelligent surface aided communication system

Digital Communications and Networks
When deploying Reconfigurable Intelligent Surface (RIS) to improve System Sum-Rate (SSR), the timeliness and accuracy of SSR optimization methods are difficult to achieve simultaneously through a single algorithm.
