      Reasoning about actions and change in answer set programming 

      Dimopoulos, Yannis; Kakas, Antonis C.; Michael, Loizos (Springer Verlag, 2004)
      This paper studies computational issues related to the problem of reasoning about actions and change (RAC) by exploiting its link with the Answer Set Programming paradigm. It investigates how increasing the expressiveness ...

      Towards local search for answer sets 

      Dimopoulos, Yannis; Sideris, A. (2002)
      Answer set programming has emerged as a new important paradigm for declarative problem solving. It relies on algorithms that compute the stable models of a logic program, a problem that is, in the worst-case, intractable. ...
