global results on some nonlinear partial differential equations for direct and inverse problems
در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...
Some solvable subclasses of structural recognition problems
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...

متن کاملSome Remarks on the Design of Constraint Satisfaction Problems
The development of a system based on constraint programming includes two main phases: first, the problem to be solved is formulated as a constraint satisfaction problem; then, the formulation is implemented in a constraint-programming language. Constraint-programming research has mainly concentrated on the second phase, by studying powerful declarative languages that automatically propagate the...
متن کاملOn some network design problems with degree constraints
We study several network design problems with degree constraints. For the minimum-cost Degree-Constrained 2-Node-Connected Subgraph problem, we obtain the first non-trivial bicriteria approximation algorithm, with factor 6 violation for the degrees and a 4-approximation for the cost. This improves upon the logarithmic degree violation and no cost guarantee obtained by Feder, Motwani, and Zhu (2...
