  • Method Details

    • getVarsList

      java.util.List<java.lang.Integer> getVarsList()
       The linear terms of the objective to minimize.
 For a maximization problem, one can negate all coefficients in the
 objective and set a scaling_factor to -1.
      repeated int32 vars = 1;
      Returns:
      A list containing the vars.

    • getVarsCount

      int getVarsCount()
       The linear terms of the objective to minimize.
 For a maximization problem, one can negate all coefficients in the
 objective and set a scaling_factor to -1.
      repeated int32 vars = 1;
      Returns:
      The count of vars.

    • getVars

      int getVars​(int index)
       The linear terms of the objective to minimize.
 For a maximization problem, one can negate all coefficients in the
 objective and set a scaling_factor to -1.
      repeated int32 vars = 1;
      Parameters:
      index - The index of the element to return.
      Returns:
      The vars at the given index.

    • getCoeffsList

      java.util.List<java.lang.Long> getCoeffsList()
      repeated int64 coeffs = 4;
      Returns:
      A list containing the coeffs.

    • getCoeffsCount

      int getCoeffsCount()
      repeated int64 coeffs = 4;
      Returns:
      The count of coeffs.

    • getCoeffs

      long getCoeffs​(int index)
      repeated int64 coeffs = 4;
      Parameters:
      index - The index of the element to return.
      Returns:
      The coeffs at the given index.

    • getOffset

      double getOffset()
       The displayed objective is always:
   scaling_factor * (sum(coefficients[i] * objective_vars[i]) + offset).
 This is needed to have a consistent objective after presolve or when
 scaling a double problem to express it with integers.
 Note that if scaling_factor is zero, then it is assumed to be 1, so that by
 default these fields have no effect.
      double offset = 2;
      Returns:
      The offset.

    • getScalingFactor

      double getScalingFactor()
      double scaling_factor = 3;
      Returns:
      The scalingFactor.

    • getDomainList

      java.util.List<java.lang.Long> getDomainList()
       If non-empty, only look for an objective value in the given domain.
 Note that this does not depend on the offset or scaling factor, it is a
 domain on the sum of the objective terms only.
      repeated int64 domain = 5;
      Returns:
      A list containing the domain.

    • getDomainCount

      int getDomainCount()
       If non-empty, only look for an objective value in the given domain.
 Note that this does not depend on the offset or scaling factor, it is a
 domain on the sum of the objective terms only.
      repeated int64 domain = 5;
      Returns:
      The count of domain.

    • getDomain

      long getDomain​(int index)
       If non-empty, only look for an objective value in the given domain.
 Note that this does not depend on the offset or scaling factor, it is a
 domain on the sum of the objective terms only.
      repeated int64 domain = 5;
      Parameters:
      index - The index of the element to return.
      Returns:
      The domain at the given index.
