A tight -approximation for Linear 3-Cut
We investigate the approximability of the linear 3-cut problem in directed graphs, which is the simplest unsolved case of the linear k-cut problem. The input here is a directed graph D = (V,E) with node weights and three specified terminal nodes s, r, t ∈ V , and the goal is to find a minimum weight subset of non-terminal nodes whose removal ensures that s cannot reach r and t, and r cannot rea...
متن کاملtight frame approximation for multi-frames and super-frames
در این پایان نامه یک مولد برای چند قاب یا ابر قاب تولید شده تحت عمل نمایش یکانی تصویر برای گروه های شمارش پذیر گسسته بررسی خواهد شد. مثال هایی از این قاب ها چند قاب های گابور، ابرقاب های گابور و قاب هایی برای زیرفضاهای انتقال پایاست. نشان می دهیم که مولد چند قاب تنک نرمال شده (ابرقاب) یکتا وجود دارد به طوری که مینیمم فاصله را از ان دارد. همچنین مسایل مشابه برای قاب های دوگان مطرح شده و برخی ...
15 صفحه اولA Tight Linear Time ( 1 / 2 ) - Approximation for Unconstrained Submodular
Consider a manager hiring workers to staff a new factory. Moving from zero employees to a thousand employees exponentially increases the factory’s production. Recognizing a pattern, the manager again hires a thousand employees. This increase in workers also raises factory production because machines are now used more efficiently, but the effect is not quite as dramatic as opening the factory fr...
متن کاملTight Local Approximation Results for Max-Min Linear Programs
In a bipartite max-min LP, we are given a bipartite graph G = (V ∪ I ∪ K,E), where each agent v ∈ V is adjacent to exactly one constraint i ∈ I and exactly one objective k ∈ K. Each agent v controls a variable xv. For each i ∈ I we have a nonnegative linear constraint on the variables of adjacent agents. For each k ∈ K we have a nonnegative linear objective function of the variables of adjacent...
متن کاملa new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
