示例1: utility
/// todo: weigh result with a "distance" from the constraint boundary
float NumericalRelationship::utility(const Offer& offer) const
{
const Attribute* offerAttribute = offer.getAttribute(m_name);
//qDebug() << "Offer attribute of name " << m_name << offerAttribute;
if (!offerAttribute)
return 1.0; // we don't know -> no violation
const NumericalAttribute* numericalOfferAttribute = dynamic_cast<const NumericalAttribute*>(offerAttribute);
if (!numericalOfferAttribute)
return 0; // wrong type
float baseUtility = Relationship::utility(offer);
if (m_type & Relationship::SmallerThan &&
*numericalOfferAttribute > static_cast<const NumericalAttribute&>(m_attribute))
baseUtility = 0;
if (m_type & Relationship::LargerThan &&
*numericalOfferAttribute < static_cast<const NumericalAttribute&>(m_attribute))
baseUtility = 0;
//qDebug() << "Returning: " << baseUtility;
return baseUtility;
