v1.0.1

API Enhancements

• The lin_cost parameter in init_sos_problem() is now optional for greater flexibility when formulating SOS problems.
• Renamed sos_smr (SOS Square Matricial Representation) to gram_matrix to better reflect its role in specifying the Q matrix in SOS decomposition p = Z^T Q Z.
• Added like argument to define_symmetric_matrix() allowing size specification by referencing another matrix expression.

Bug Fixes & Edge Cases

• Fixed edge case in define_multiplier() where the degree of the multiplicand could exceed the specified degree.

v1.0.0

New Features

1. Complete SOS decomposition
   • Added support for a full SOS decomposition (complementing the existing heuristic)
   • Enable this via state = sosopt.init_state(sparse_smr=False)
2. Enhanced Constraint Definitions
   • Semidefinite constraints: Directly enforce matrix positivity in SOS problems.
   • Equality constraints: Enforce equality constraints in SOS problems.
