Statistical uncertainty of different filtration techniques for market network analysis is studied. Two measures of statistical uncertainty are discussed. One is based on conditional risk for multiple decision statistical procedures and another one is based on average fraction of errors. It is...

The earliest approaches to the cell formation problem in group technology, dealing with a binary machine-part incidence matrix, were aimed only at minimizing the number of intercell moves (exceptional elements in the block-diagonalized matrix). Later on this goal was extended to simultaneous...

Graph coloring is an important tool in the study of optimization, computer science, network design, e.g., file transferring in a computer network, pattern matching, computation of Hessians matrix and so on. In this paper, we consider one important coloring, vertex coloring of a total graph,...

The inverse max + sum spanning tree (IMSST) problem is studied, which is the first inverse problem on optimization problems with combined minmax–minsum objective functions. Given an edge-weighted undirected network <InlineEquation ID="IEq3"> <EquationSource Format="TEX">$$G(V,E,c,w)$$</EquationSource> <EquationSource Format="MATHML"> <math xmlns:xlink="http://www.w3.org/1999/xlink"> <mrow> <mi>G</mi> <mo stretchy="false">(</mo> <mi>V</mi> <mo>,</mo> <mi>E</mi> <mo>,</mo> <mi>c</mi> <mo>,</mo> <mi>w</mi> <mo stretchy="false">)</mo> </mrow> </math> </EquationSource> </InlineEquation>, the MSST problem is to find a...</equationsource></equationsource></inlineequation>

Cooperative networks have gained a tremendous amount of attention over the last several years because of their existence not only in biological, social and economic arenas, but because of direct applications in many more areas such as communications, robotics and military sciences. This volume...
