Finding smallest supertrees under minor containment
(1999-10)
Report de recerca
Accés obertThe diversity of application areas relying on tree-structured data results in a wide interest in algorithms which determine differences or similarities among trees. One way of measuring the similarity between trees ... -

Groupoids and Faà di Bruno formulae for Green functions in bialgebras of trees
(2014)
Article
Accés restringit per política de l'editorialWe prove a Faà di Bruno formula for the Green function in the bialgebra of P-trees, for any polynomial endofunctor P. The formula appears as relative homotopy cardinality of an equivalence of groupoids. -

Location routing problems on trees
(2019-04-30)
Article
Accés obertThis paper addresses combined location/routing problems defined on trees, where not all vertices have to be necessarily visited. A mathematical programming formulation is presented, which has the integrality property. The ... -
Marked graphs and the chromatic symmetric function
(2023-09-30)
Article
Accés obertThe main result of this paper is the introduction of marked graphs and the marked graph polynomials ( -polynomial) associated with them. These polynomials can be defined via a deletion-contraction operation. These polynomials ... -
On the maximum common embedded subtree problem for ordered trees
(2003-03)
Report de recerca
Accés obertThe maximum common embedded subtree problem, which generalizes the subtree homeomorphism problem, is reduced for ordered trees to a variant of the longest common subsequence problem, called the longest common balanced ... -
Quasiperfect domination in trees
(2015-12-18)
Article
Accés obertA k–quasiperfect dominating set ( k=1k=1) of a graph G is a vertex subset S such that every vertex not in S is adjacent to at least one and at most k vertices in S. The cardinality of a minimum k–quasiperfect dominating ... -
