Class StructuredCSPModel

java.lang.Object
  ifs.model.Model
      ifs.example.csp.StructuredCSPModel

public class StructuredCSPModel
extends Model

Random Binary CSP with kernels.

This class only implements the generation of Structured CSP problem.
In Structured CSP, variables are divided into several kernels (some variables may remain ouside kernels). Different constraints (in density and tightnes) are generated according to whether variables are from the same kernel or not.

Model parameters:

Parameter	Type	Comment
CSP.NrVariables	Integer	Number of variables
CSP.DomainSize	Integer	Number of values for each variable
CSP.NrKernels	Integer	Number of kernels
CSP.KernelSize	Integer	Number of variables in each kernel
CSP.Tightness	Double	Tightness of constraints outside kernels
CSP.KernelTightness	Double	Tightness of constraints inside a kernel
CSP.Density	Double	Density of constraints outside kernels
CSP.KernelDensity	Double	Density of constraints inside a kernel
General.MPP	String	Minimal perturbation problem --> generate initial assignment
