On stability of a Pareto-optimal solution under perturbations of the parameters for a multicriteria combinatorial partition prob
Abstract. We consider a multicriteria variant for the wellknown partition problem. A formula of the stability radius for an efficient solution was obtained. Mathematics Subject Cl...

An edge colouring of multigraphs
We consider a strict k-colouring of a multigraph G as a surjection f from the vertex set of G into a set of colours {1,2,. . . ,k} such that, for every non-pendant vertex x of G, ...
