The problem of the r-identifying code of a cycle Cn has been solved totally when n is even. Recently, S. Gravier et al. give the r-identifying code for the cycle Cn with the minim...
Several optimization problems require finding a permutation of a given set of items that minimizes a certain cost function. These problems are naturally modelled in graph-theory t...

We show that many rational parametric curves can be interpolated, in a Hermite sense, by polynomial curves whose degree, relative to the number of data being interpolated, is lowe...
The aim of this article is to link Schubert varieties in the flag manifold with hyperplane arrangements. For a permutation, we construct a certain graphical hyperplane arrangement....
ct 7 Two third order methods for finding multiple zeros of nonlinear functions are developed. One method is based on 8 Chebyshev's third order scheme (for simple roots) and th...
