We consider minimal controllability problems (MCPs) on linear structural descriptor systems. address two of determining the minimum number input nodes such that a system is structurally controllable. show MCP0 for systems can be solved in polynomial time. This same as existing results typical time invariant (LTI) However, derivation result considerably different because technique cannot used In...

The objective considering such issues is offer Arab critic with ways deal and overcome substantial challenges Appro...

During the last decades a lot of applied structural recognition problems came to light which might be reduced to consistent labelling problems. The consistent labelling problem and its appropriate fuzzy and probabilistic modifications became a proper formalism for a unified formulation of such problems regardless of their specific applied contents. On the other hand there is no formal construct...
