Description (last modified by )
We should provide a detailed interface for symbolic relations:
bool(rel)
equivalent to(not)(LHS-RHS).is_trivial_zero()
for ==,!= ; and for <, >, <=, >= the result follows alpha order of lhs and rhssatisfiable(rel)
returning(Yes,example)/No/Undecidable/NotImplemented
solve(rel)
in case ofsatisfiable=Yes
returning the full solution setis(rel)
attempting simplification/proof, returningTrue
/False
, throwingNotImplementedError
ex.is_zero(simplify=False)
(default) calling the fastbool(ex==0)
(#24992)ex.is_zero(simplify=True)
attempting simplification/proof (#24992)prove(rel)
showing more or less steps of simplification (which is out of reach for the moment)
