A New NCAlgorithm for Perfect Matching in Bipartite Cubic Graphs
The purpose of this paper is to introduce a new approach to the problem of computing perfect matchings in fast deterministic parallel time. In particular, this approach yields a new algorithm which finds a perfect matching in bipartite cubic graphs in time O log n and O n n logn processors in the arbitrary CRCW PRAM model.

چکیده رساله/پایان نامه : تاکنون روشهای متعددی در ارتباط با مکان یابی خطا در شبکه انتقال ارائه شده است. استفاده مستقیم از این روشها در شبکه توزیع به دلایلی همچون وجود انشعابهای متعدد، غیر یکنواختی فیدرها (خطوط کابلی، خطوط هوایی، سطح مقطع متفاوت انشعاب ها و تنه اصلی فیدر)، نامتعادلی (عدم جابجا شدگی خطوط، بارهای تکفاز و سه فاز)، ثابت نبودن بار و اندازه گیری مقادیر ولتاژ و جریان فقط در ابتدای...
passivity in waiting for godot and endgame: a psychoanalytic reading
this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
Linear-Time Algorithm for Maximum-Cardinality Matching on Cocomparability Graphs
Finding maximum-cardinality matchings in undirected graphs is arguably one of the most central graph problems. For general m-edge and n-vertex graphs, it is well-known to be solvable in O(m √ n) time. We develop the first linear-time algorithm to find maximumcardinality matchings on cocomparability graphs, a prominent subclass of perfect graphs that contains interval graphs as well as permutati...
متن کاملOn Perfect Matchings in Matching Covered Graphs
Let G be a matching-covered graph, i.e., every edge is contained in a perfect matching. An edge subsetX ofG is feasible if there exists two perfect matchingsM1 andM2 such that |M1∩X| 6≡ |M2∩X| (mod 2). Lukot’ka and Rollová proved that an edge subset X of a regular bipartite graph is not feasible if and only if X is switching-equivalent to ∅, and they further ask whether a non-feasible set of a ...
