In this work, we study an approximate control problem for the heat equation, with a nonstandard but rather natural restriction on the solution. It is well known that approximate controllability holds. On the other hand, the total mass of the solutions of the uncontrolled system is constant in time. Therefore, it is natural to analyze whether approximate controllability holds supposing the total...

The graph bandwidth problem, where one looks for a labeling of vertices that gives the minimum difference between labels over all edges, is classical NP-hard problem has drawn lot attention in recent decades. In this paper, we focus on so-called Embed and Project Algorithm (EPA) introduced by Blum et al. 2000, which main part to solve semidefinite programming relaxation with exponentially many ...

With the existence of ambiguity in the financial processes of projects, fuzzy concepts are being implemented into the foundation and essence of the current article. Authors have employed chance constrained programming and simulated annealing as appropriate tools for determining the net present worth value of several projects. At the end, the most economical project was chosen. In this article, ...
