Public Methods

Method	Description
Add ( ) : void	Alias for Assert.
Assert ( ) : void	Assert a constraint (or multiple) into the solver.
AssertAndTrack ( BoolExpr constraints, BoolExpr ps ) : void	Assert multiple constraints into the solver, and track them (in the unsat) core using the Boolean constants in ps. This API is an alternative to Check with assumptions for extracting unsat cores. Both APIs can be used in the same solver. The unsat core will contain a combination of the Boolean variables provided using AssertAndTrack(BoolExpr[],BoolExpr[]) and the Boolean literals provided using Check with assumptions.
Check ( ) : Status	Checks whether the assertions in the solver are consistent or not. Model UnsatCore Proof
Pop ( uint n = 1 ) : void	Backtracks n backtracking points. Note that an exception is thrown if n is not smaller than `NumScopes`
Push ( ) : void	Creates a backtracking point.
Reset ( ) : void	Resets the Solver. This removes all assertions from the solver.
ToString ( ) : string	A string representation of the solver.

Method Details

Add() public method

Alias for Assert.

public Add ( ) : void
return	void

Assert() public method

Assert a constraint (or multiple) into the solver.

public Assert ( ) : void
return	void

AssertAndTrack() public method

Assert multiple constraints into the solver, and track them (in the unsat) core using the Boolean constants in ps.

This API is an alternative to Check with assumptions for extracting unsat cores. Both APIs can be used in the same solver. The unsat core will contain a combination of the Boolean variables provided using AssertAndTrack(BoolExpr[],BoolExpr[]) and the Boolean literals provided using Check with assumptions.

public AssertAndTrack ( BoolExpr constraints, BoolExpr ps ) : void
constraints	BoolExpr
ps	BoolExpr
return	void

Check() public method

Checks whether the assertions in the solver are consistent or not.

Model UnsatCore Proof

public Check ( ) : Status
return	Status

Pop() public method

Backtracks n backtracking points.

Note that an exception is thrown if n is not smaller than NumScopes

public Pop ( uint n = 1 ) : void
n	uint
return	void

Push() public method

Creates a backtracking point.

public Push ( ) : void
return	void

Reset() public method

Resets the Solver.

This removes all assertions from the solver.

public Reset ( ) : void
return	void

ToString() public method

A string representation of the solver.

public ToString ( ) : string
return	string
