Detailed Description

template<typename ParametricType, typename ConstantType>
class storm::transformer::RobustParameterLifter< ParametricType, ConstantType >

This class lifts parameter choices to nondeterminism: For each row in the given matrix that considerd par parameters, the resulting matrix will have one row group consisting of 2^par rows.

When specifying a region, each row within the row group is evaluated w.r.t. one vertex of the region. The given vector is handled similarly. However, if a vector entry considers a parameter that does not occur in the corresponding matrix row, the parameter is directly set such that the vector entry is maximized (or minimized, depending on the specified optimization direction).

Note: The row grouping of the original matrix is ignored.

◆ RobustParameterLifter()

template<typename ParametricType , typename ConstantType >

storm::transformer::RobustParameterLifter< ParametricType, ConstantType >::RobustParameterLifter	(	storm::storage::SparseMatrix< ParametricType > const &	pMatrix,
		std::vector< ParametricType > const &	pVector,
		storm::storage::BitVector const &	selectedRows,
		storm::storage::BitVector const &	selectedColumns,
		bool	generateRowLabels = `false`,
		bool	useMonotonicity = `false`
	)

Lifts the parameter choices to nondeterminisim.

The computation is performed on the submatrix specified by the selected rows and columns

Parameters

pMatrix	the parametric matrix
pVector	the parametric vector (the vector size should equal the row count of the matrix)
selectedRows	a Bitvector that specifies which rows of the matrix and the vector are considered.
selectedColumns	a Bitvector that specifies which columns of the matrix are considered.
