Analysis of Generalized Pattern Searches
This paper contains a new convergence analysis for the Lewis and Torczon GPS class of pattern search methods for linearly constrained optimization. The ana...
référence BibTeXPanchromatic Chains and Paths
A generalization of the Roy-Gallai theorem on the chromatic number of a graph is derived which is also an extension of several other results of Berge and of...
référence BibTeXIntegral Complete Split Graphs
We give characterizations of integral graphs in the family of complete split graphs and a few related families of graphs.
