Undocumented |
Method | add |
Adds constraint(s) to constraints list. |
Method | batch |
Evaluates `exprs`, returning a list of tuples (one tuple of `n` solutions for expression). |
Method | blank |
Undocumented |
Method | branch |
Undocumented |
Method | check |
Checks the satisfiability of stored constraints conjunction. |
Method | combine |
Undocumented |
Method | downsize |
Undocumented |
Method | eval |
Evaluates expression `e`, returning a tuple of `n` solutions. |
Method | eval |
Evaluates expression `e`, returning a list of `n` concrete ASTs. |
Method | finalize |
Undocumented |
Method | is |
Checks if `e` can only (and TRIVIALLY) evaluate to False. If this function returns True, then the expression cannot ever be True, regardless of constraints or anything else. If the expression returns False, then the expression might STILL not ever be True; it's just that we can't trivially prove it... |

Method | max |
Evaluates `e`, returning its max possible value. |

Undocumented |
Method | min |
Evaluates `e`, returning its min possible value. |
Method | satisfiable |
Checks if stored constraints conjunction is satisfiable. |
Method | simplify |
Simplifies the stored constraints conjunction. |
Method | solution |
Checks if `v` is a possible solution to `e`. |

Undocumented |
Static Method | _split |
Returns independent constraints, split from this Frontend's `constraints`. |

Checks the satisfiability of stored constraints conjunction. :param extra_constraints: extra constraints to consider when checking satisfiability :param exact: whether or not to perform exact checking.

If the expression returns False, then the expression might STILL not ever be True; it's just that we can't trivially prove it. In other words, a return value of False gives you no information whatsoever. :param e: the expression :param extra_constraints: extra constraints to consider when performing the evaluation :param exact: whether or not to perform an exact evaluation.
