      On se propose d'utiliser la méthode que P. Flajolet a décrit pour prouver l'ambiguité du langage de Goldstine [5], afin de prouver l'ambiguité d'une série de langages du même type. Ces langages sont tous des complémentaires ...

    • Concurrent AVL revisited: self-balancing distributed search trees 

      Bougé, Luc; Gabarró Vallès, Joaquim; Messeguer Peypoch, Xavier (1996-01)
      Report de recerca
      Accés obert
      We address the concurrent insertion and deletion of keys in binary almost balanced search trees (AVL trees). We show that this problem can be studied through the self-reorganization of distributed systems of processes ...

    • Concurrent rebalancing of AVL trees: a fine-grained approach

      Report de recerca
      Accés obert
      We address the concurrent rebalancing of almost balanced binary search trees (AVL trees). Such a rebalancing may for instance be necessary after successive insertions and deletions of keys. We show that this ...

    • Concurrent rebalancing on hyperred-black trees 

      Gabarró Vallès, Joaquim; Messeguer Peypoch, Xavier; Daniel, Riu (1997-05)
      Report de recerca
      Accés obert
      The HyperRed-Black trees are a relaxed version of Red-Black trees accepting high degree of concurrency. In the Red-Black trees consecutive red nodes are forbidden. This restriction has been withdrawn in the Chromatic ...

    • Connections among non uniform models for problems requiring high amount of resources 

      Balcázar Navarro, José Luis; Gabarró Vallès, Joaquim (1985-11)
      Report de recerca
      Accés obert
      We characterize in terms of oracle Turing machines the classes defined by exponential lower bounds on some nonuniform complexity measures. After, we use the same methods to give a new characterization of classes defined ...

    • Continuous assessment in the evolution of a CS1 course: The pass rate/workload ratio

      Text en actes de congrés
      Accés obert
      Teaching computer science in degrees that are not computer science related presents an important challenge: to motivate the students and to achieve good average grades. The student’s complaint is always based ...

    • De menos a distinto: estudio de la implantación de R en las asignaturas del grado de estadística 

      Baixeries i Juvillà, Jaume; Fairén González, Marta; Gabarró Vallès, Joaquim; Pasarella Sánchez, Ana Edelmira (Universidad de Almería, 2016-07-05)
      Comunicació de congrés
      Accés obert
      Los cursos de informática en las titulaciones que no son informáticas siempre pecan de falta de motivación y buenos resultados de los estudiantes. El argumento del estudiante acostumbra a ser: ¿A mí para que me servirá ...

    • Deciding bisimilarity is P-complete 

      Balcázar Navarro, José Luis; Gabarró Vallès, Joaquim; Santha, Miklos (1990)
      Report de recerca
      Accés obert
      On finite labelled transition systems, the problems of deciding strong bisimilarity, observation equivalence, and observation congruence are P-complete under many-one NC-reducibility. As a consequence, algorithms for ...
