1.10

• New: The function generate_operators returns a list of operators from the sympy.physics.quantum submodule. This is the old behaviour of generate_variables.
• New: The SdpRelaxation class is now subscriptable. You can retrieve the value of polynomials in the solved relaxation in such way. Internally, it calls get_xmat_value with self.
• New: The convenience method solve() was added to the class SdpRelaxation.
• New: The convenience method write_to_file() was added to the class SdpRelaxation.
• New: The convenience method save_monomial_index() was added to the class SdpRelaxation.
• New: The convenience method find_solution_ranks() was added to the class SdpRelaxation. It replaces the previous stand-alone find_rank_loop() function.
• New: The conversion routines convert_to_picos and convert_to_mosek are also part of the class sdpRelaxation.
• New: The new method extract_dual_value() was added to the class SdpRelaxation to calculate the inner product of the coefficient matrix of an SDP variable with the dual solution.
• New: The class RdmHierarchy was added to generate SDPs of the reduced density matrix method. Initial support for 1D spinless, translational invariant systems is included.
• New: Better support for the steering hierarchy in a new class SteeringHierarchy.
• Changed: The function generate_variables are now returns a list of sympy.Symbol variables if commutative variables are requested, and the default is commutative.
• Changed: Many unnecessary user-facing functions were removed.
• Changed: The SOS decomposition is now requested with get_sos_decomposition from the class SdpRelaxation, and it returns a list of the sigma_i polynomials.
• Changed: The optional parameter bounds for get_relaxation is deprececated, use the optional parameters momentinequalities and momentequalities instead.
• Changed: Removed convert_to_picos_extra_moment_matrix and added optional parameter duplicate_moment_matrix to convert_to_picos to achieve the same effect.
• Changed: The chordal extension is now requested as an optional parameter chordal_extension=True passed to the get_relaxation method, and not by specifying it as a hierarchy type in the constructor.
• Changed: The Moroder hierarchy is now a class.
• Changed: Small improvements in speed in the substitution routines; unit tests for the substitution routines.
• Changed: The read_sdpa_out routine takes an optional argument for a relaxation, and adds the solution to this object if requested.
• Changed: Instead of an examples folder, all examples were migrated to the documentation.
• Changed: The symbolic variables which are not to be relaxed are now supplied to the constructor with the optional parameter parameters.
• Changed: Redundant positive-semidefinite constraint type removed.
• Fixed: PICOS and MOSEK conversion works for complex matrices too (issue #10).
• Fixed: The moment symmetries are correctly calculated for both Hermitian and non-Hermitian variables (issue #9)
