Enumeration Type Documentation

◆ Answer

enum mcrl2::data::detail::Answer

A prover that uses EQ-BDDs.

\detail A class based on the Prover class that takes an expression of sort Bool in internal mCRL2 format and creates the corresponding EQ-BDD. Using this EQ-BDD, the class can determine if the original formula is a tautology or a contradiction. The term "formula" in the following text denotes arbitrary expressions of sort Bool in the mCRL2 format.

A prover uses a rewriter to rewrite parts of the formulas it manipulates. The constructor BDD_Prover::BDD_Prover initializes the prover's rewriter with the data equations in internal mCRL2 format contained in the LPS passed as parameter a_lps and the rewrite strategy passed as parameter a_rewrite_strategy. The parameter a_rewrite_strategy can be set to either GS_REWR_data::jitty or GS_REWR_data::jittyC. To limit the number of seconds spent on proving a single formula, a time limit can be set. If the time limit is set to 0, no time limit will be enforced. The parameter a_apply_induction indicates whether or induction on lists is applied. The constructor BDD_Prover::BDD_Prover has two additional parameters, a_path_eliminator and a_solver_type. The parameter a_path_eliminator can be used to enable the use of an instance of the class BDD_Path_Eliminator. Instances of this class use an SMT solver to eliminate inconsistent paths from BDDs. The parameter a_solver_type can be used to indicate which SMT solver should be used for this task. Either the SMT solver ario (http://www.eecs.umich.edu/~ario/) or cvc-lite (http://www.cs.nyu.edu/acsys/cvcl/) can be used. To use one of these solvers, the directory containing the corresponding executable must be in the path. If the parameter a_path_eliminator is set to false, the parameter a_solver_type is ignored and no instance of the class BDD_Path_Eliminator is initialized.

The formula to be handled is set using the method Prover::set_formula inherited from the class Prover. An entity of the class BDD_Prover uses binary decision diagrams to determine if a given formula is a tautology or a contradiction. The resulting BDD can be retreived using the method BDD_Prover::get_bdd.

The methods BDD_Prover::is_tautology and BDD_Prover::is_contradiction indicate whether or not a formula is a tautology or a contradiction. These methods will return answer_yes, answer_no or answer_undefined. If a formula is neither a tautology nor a contradiction according to the prover, a so called witness or counter example can be returned by the methods BDD_Prover::get_witness and BDD_Prover::get_counter_example. A witness is a valuation for which the formula holds, a counter example is a valuation for which it does not hold.

◆ split_condition_aux()

		std::vector< data_expression_list > &	real_conditions,
		std::vector< data_expression_list > &	non_real_conditions,
		const bool	negate = `false`
	)

static

Splits a condition in expressions ranging over reals and the others.

Conceptually, the condition is first transformed to disjunctive normal form. For each disjunct, there will be an entry in both resulting std::vectors, where the real conditions are in "real_conditions", and the others in non_real_conditions. If there are conjuncts with both real and non-real variables an exception is thrown. If negate is true the result will be negated.

Parameters

e	A data expression of sort bool.
real_condition	Those parts of e with only variables over sort Real.
non_real_condition	Those parts of e with only variables not of sort Real.
negate	A boolean variable that indicates whether the result must be negated.

Returns: True when e contains real variables

Precondition: The parameter e must be of sort Bool.
