We consider the CONGEST model on a network with n nodes, m edges, diameter D, and integer costs capacities bounded by $${{\,\textrm{poly}\,}}n$$ . In this paper, we show how to find an exact solution minimum cost flow problem in $$n^{1/2+o(1)}(\sqrt{n}+D)$$ rounds, improving state of art algorithm running time $$m^{3/7+o(1)}(\sqrt{n}D^{1/4}+D)$$ [16], which only holds for special case unit capa...

Smooth implementation and controlling conflicting goals of a project with the usage of all related resources through organization is inherently a complex task to management. At the same time deterministic models are never efficient in practical project management (PM) decision problems because the related parameters are frequently fuzzy in nature. The project execution time is a major concern o...

A hidden Markov model is introduced for descriptive modelling the mosaic–like structures of haplotypes, due to iterated recombinations within a population. Methods using the minimum description length principle are given for fitting such models to training data. Possible applications of the models are delineated, and some preliminary analysis results on real sets of haplotypes are reported, dem...

The goal of this paper is to show how the concept of fuzzy logic can be used to establish a degree to which an investment project belongs to a class of risk. Also, the probability of the fuzzy event is presented and is ap-plied to calculate the probability of the fuzzy event “the project X is a good investment”. This process has to enable the decision maker to compare several alternative invest...
