Constructor & Destructor Documentation

Implicative::Implicative	(	int	ns,
		bool *	quant,
		int *	nv
	)

Default constructor for a restricted-quantified space.

This is the first step for building a QCSP+/QCOP+ problem. The prefix is defined here.

Parameters:

	ns	The number of scopes in the prefix.
	quant	Array of booleans which contains the quantifier of every scope (true for universal, false for existential).
	nv	Array of integer which contains the number of variables by scope.

MySpace * Implicative::space ( )

Returns the current declarating space.

Return the space we are currently declarating constraints in. nextScope() is used to set the nextspace as the current one.

IntVar Implicative::var ( int n )

Returns an integer variable from the space we are currently declaring.

Returns an integer variable from the cpace we are currently declaring. Will abort if the variable is not integer.

Parameters:

The number of the variable to return.

BoolVar Implicative::bvar ( int n )

Returns a boolean variable from the space we are currently declaring.

Returns a boolean variable from the space we are currently declaring. Will abort if the variable is not boolean.

Parameters:

The number of the variable to return.

int Implicative::nextScope ( )

Switch to the next space for constraint declaration.

Switches to the next space for constraint declaration. var, bvar and space methods will now refer to the next rule space (or to the goal space if the current space was the last rule one). Returns the new space number, or -1 if it was called while there was no next space to declare constraints in.

void Implicative::makeStructure ( )

Finalizes the object construction.

Finalizes the restricted-quantified space construction. Must be invoked once all the variable and all the constraints have been declared, and before the search is performed on this space. calling this method is not mandatory, although it is recommanded to besure that the problem have been well built. For the existential scopes on which an optimization condition have not been defined yet, this method will post a "Any" optimization condition (i.e. do not optimize).

OptVar * Implicative::getAggregate	(	int	scope,
		OptVar *	opt,
		Aggregator *	agg
	)

returns an aggregate of the problem

Creates an aggregate at a given universal scope. This aggregate is an optimization variable that an existential scope can use for optimizing.

Parameters:

	scope	the scope where this aggregate will be defined. Must be an unversal scope
	opt	The optimization variable we want to aggregate. There must not be any universal scope between an agregate and thisoptimization variable.
	agg	The aggregator function that will be used for this aggregate.

OptVar * Implicative::getExistential ( int var )

returns an existential optimization variable

Creates an optimization variable that will have the value of an existential variable defined in the problem.

Parameters:

var

the number of the existential variable that must be considered

void Implicative::optimize	(	int	scope,
		int	optType,
		OptVar *	var
	)

set an optimization condition on an existential scope

set an optimization condition on a given existential scope of the problem. An optimizaiton condition is composed of an optimization variable (aggregate or existential variable), and of an optimization type.

Parameters:

	scope	the scope on which the optimization condition is posted. Must be existential.
	optType	the optimization type of the condision we post. 0 is for ANY, 1 is for MIN, 2 is for MAX.
	var	the optimization variable to be minimized/maximized
