MonotonicityHelper()

template<typename ValueType , typename ConstantType >

storm::analysis::MonotonicityHelper< ValueType, ConstantType >::MonotonicityHelper	(	std::shared_ptr< models::sparse::Model< ValueType > >	model,
		std::vector< std::shared_ptr< logic::Formula const > >	formulas,

		uint_fast64_t	numberOfSamples = 0,
		double const &	precision = 0.000001,
		bool	dotOutput = false
	)

Constructor of MonotonicityHelper.

Parameters

model	The model considered.
formulas	The formulas considered.
regions	The regions to consider.
numberOfSamples	Number of samples taken for monotonicity checking, default 0, if 0 then no check on samples is executed.
precision	Precision on which the samples are compared
dotOutput	Whether or not dot output should be generated for the ROs.

checkDerivative()

template<typename ValueType , typename ConstantType >

static std::pair< bool, bool > storm::analysis::MonotonicityHelper< ValueType, ConstantType >::checkDerivative ( ValueType  derivative, storage::ParameterRegion< ValueType >  reg  )

inlinestatic

Checks if a derivative >=0 or/and <=0.

Parameters

derivative

The derivative you want to check

Returns

pair of bools, >= 0 and <= 0

Definition at line 60 of file MonotonicityHelper.h.

checkLocalMonotonicity()

template<typename ValueType , typename ConstantType >

Monotonicity storm::analysis::MonotonicityHelper< ValueType, ConstantType >::checkLocalMonotonicity	(	std::shared_ptr< Order >	order,
		uint_fast64_t	state,
		VariableType	var,
		storage::ParameterRegion< ValueType >	region
	)

Checks for local monotonicity at the given state.

Parameters

order	the order on which the monotonicity should be checked
state	the considerd state
var	the variable in which we check for monotonicity
region	the region on which we check the monotonicity

Returns

Incr, Decr, Constant, Unknown or Not

checkMonotonicityInBuild()

template<typename ValueType , typename ConstantType >

std::map< std::shared_ptr< Order >, std::pair< std::shared_ptr< MonotonicityResult< typename MonotonicityHelper< ValueType, ConstantType >::VariableType > >, std::vector< std::shared_ptr< expressions::BinaryRelationExpression > > > > storm::analysis::MonotonicityHelper< ValueType, ConstantType >::checkMonotonicityInBuild	(	std::ostream &	outfile,
		bool	usePLA = false,
		std::string	dotOutfileName = "dotOutput"
	)

Builds Reachability Orders for the given model and simultaneously uses them to check for Monotonicity.

Parameters

outfile	Outfile to which results are written.
dotOutfileName	Name for the files of the dot outputs should they be generated

Returns

Map which maps each order to its Reachability Order and used assumptions.
