چکیده

We study the problem of minimal triangulation of graphs. One of the first algorithms to solve this problem is Lex M, which was presented in 1976. A new algorithm, and a simplification of Lex M, called MCS-M was presented in 2002. In this paper we compare these two algorithms and show that they produce the same set of chordal graphs, answering an open question mentioned by the authors of MCS-M.

Lex M versus MCS-M

We study the problem of minimal triangulation of graphs. One of the first algorithms to solve this problem was Lex M, which was presented in 1976. A new algorithm, and a simplification of Lex M called MCS-M, was presented in 2002. In this paper we compare these two algorithms and show that they produce the same set of triangulations, answering an open question mentioned by the authors of MCS-M.

Maximum Cardinality Search for Computing Minimal Triangulations

We present a new algorithm, called MCS-M, for computing minimal triangulations of graphs. Lex-BFS, a seminal algorithm for recognizing chordal graphs, was the genesis for two other classical algorithms: Lex-M and MCS. Lex-M extends the fundamental concept used in Lex-BFS, resulting in an algorithm that also computes a minimal triangulation of an arbitrary graph. MCS simplified the fundamental c...

ISSN 0333-3590 Primal-Dual IPMS for Semidefinite Optimization Based on Finite Barrier Functions

In this paper we extend the results obtained for a class of finite kernel functions by Y.Q. Bai M. El Ghami and C.Roos published in SIAM Journal of Optimization, 13(3):766–782, 2003 [3] for linear optimization to semidefinite optimization. We show that the iteration bound for primal dual methods is O( √ n log n log n ), for large-update methods andO( √ n log n ), for small-update methods. The i...

Probabilistic analysis of stability of chain pillars in Tabas coal mine in Iran using Monte Carlo simulation

Performing a probabilistic study rather than a determinist one is a relatively easy way to quantify the uncertainty in an engineering design. Due to the complexity and poor accuracy of the statistical moment methods, the Monte Carlo simulation (MCS) method is wildly used in an engineering design. In this work, an MCS-based reliability analysis was carried out for the stability of the chain pill...
