auto_contractor.contract_simplify(*exprs, is_isospin_symmetric_limit=True, diagram_type_dict=None)

exprs = [ expr, (expr, *included_types,), … ]

In case diagram_type_dict is not None, perform the following filter If diagram_type_dict[diagram_type] is None: term is removed. For (expr, *included_types,), only terms (in expr) with diagram_type that is in included_types is kept included_types should be a list/tuple of string
