The main purpose of this paper is to describe the design, implementation and possibilities of our object-oriented library of algorithms for dynamic optimization problems. We briefly present library classes for the formulation and manipulation of dynamic optimization problems, and give a general survey of solver classes for unconstrained and constrained… (More)
In the note an error in Low and Lapsley's article  is pointed out. Because of this error the proof of the Theorem 2 presented in the article is incomplete and
—Efforts to reduce power consumption in telecom-munication networks follow in two mutually related directions – design of a more efficient equipment and development of energy-aware network control strategies and protocols. The paper presents a formulation of two-criteria traffic engineering problem, which takes advantage of energy saving capabilities in… (More)
—We present a very simple, free tool for parallelizing calculations under Matlab in multicore and cluster environments. After the installation it does not use any compilers, MEX files, disk files, etc. It is compatible with the old Paralize package, but allows the involved cores/machines to do other jobs when a worker core/machine is not busy.
— This paper presents a newly deployed server, IDOS (Interactive Dynamic Optimization Sever), devoted to solving optimal control problems. Development and deployment of the Interactive Dynamic Optimization Server is a result of a project funded by NCBiR (National Center for Research and Development in Poland). The aim of the project was to develop a… (More)
SUMMARY This paper indicates two errors in the formulation of the main optimization model in the article " Control system for reducing energy consumption in backbone computer network " by Niewiadomska-Szynkiewicz et al. and shows how to fix them.
