Read e-book online Abstract Domains in Constraint Programming PDF

By Marie Pelleau

Constraint Programming goals at fixing demanding combinatorial difficulties, with a computation time expanding in perform exponentially. The tools are at the present time effective adequate to unravel huge commercial difficulties, in a prevalent framework. besides the fact that, solvers are devoted to a unmarried variable style: integer or genuine. fixing combined difficulties depends upon advert hoc changes. In one other box, summary Interpretation bargains instruments to end up application houses, by means of learning an abstraction in their concrete semantics, that's, the set of attainable values of the variables in the course of an execution. quite a few representations for those abstractions were proposed. they're known as summary domain names. summary domain names can combine any form of variables, or even symbolize kin among the variables.

In this paintings, we outline summary domain names for Constraint Programming, for you to construct a favourite fixing procedure, facing either integer and genuine variables. We additionally learn the octagons summary area, already outlined in summary Interpretation. Guiding the hunt via the octagonal kinfolk, we receive stable effects on a continuing benchmark. We additionally outline our fixing procedure utilizing summary Interpretation strategies, on the way to comprise present summary domain names. Our solver, AbSolute, is ready to clear up combined difficulties and use relational domains.

  • Exploits the over-approximation the right way to combine AI instruments within the tools of CP
  • Exploits the relationships captured to unravel non-stop difficulties extra effectively
  • Learn from the builders of a solver in a position to dealing with virtually all summary domains
