A Fast Scaling Algorithm for the Weighted Triangle-Free 2-Matching Problem, So far, no efficient cost-scaling algorithm is known for finding a minimum-cost perfect triangle-free 2-matching. The present paper fills this gap by presenting such an algorithm with time complexity of ..

V. Shyamala Susan,A. P. Bambang Sugiyonoty, there are Freckle graphs where the greedy independent set algorithm is objectively less good than another algorithm..It is shown that it is .-hard to determine any of the following for a given graph: the online independence number, the online vertex cover number, and the online domination number.

O. M. Belotserkovskii,A. S. Kholodov enumerating acyclic orientations. We show that the problem is of independent interest from both combinatorial and algorithmic points of view, and that each cyclic orientation can be listed with . delay time. Space usage is .(.) with an additional setup cost of . time before the enumeration begins, or .(.) with a setup cost of . time.

Dynamic Size Effect in Concrete Materials,(sub)trees. In particular, focusing on subtree computations, we show how to customize the data structure in order to answer queries for a concrete application: keeping track of the biconnectivity measures, including the impact of the removal of articulation points, of a dynamic undirected graph.

Ghicaus to determine polynomial-time approximation algorithms for different classes of graphs such as regular graphs, connected graphs and forests, but also for general graphs. Concerning exact algorithms, we show that the problem is solvable in . time, and that deciding whether there exist a labeling . of . such that . is solvable in ..
