Abstract:
In terms of systems of subsets, we describe a rather wide class of problems
on combinatorial vector optimization which are unsolvable by the classical
technique of linear convolution of criteria. This class includes, in particular,
some well-known problems on graphs (the travelling salesman problem, the
problem on a path between vertices and perfect matching problem,
the problem on $p$-median and the problem on covering a graph by paths)
as well as various Boolean programming problems
with vector-valued criterion function being an arbitrary combination
of criteria of the form $\maxsum$, $\maxmin$, $\maxmax$. This work was partially supported by the Foundation for Basic Researches of
the Republic of Byelorussia.
