Here is the call graph for this function:

bool ConstraintTeacherMaxHoursContinuously::computeInternalStructure ( QWidget *  parent,
Rules r 
) [virtual]

Computes the internal structure for this constraint.

It returns false if the constraint is an activity related one and it depends on only inactive activities.

double ConstraintTeacherMaxHoursContinuously::fitness ( Solution c,
Rules r,
QList< double > &  cl,
QList< QString > &  dl,
QString *  conflictsString = NULL 
) [virtual]

The function that calculates the fitness of a solution, according to this constraint.

We need the rules to compute this fitness factor. If conflictsString!=NULL, it will be initialized with a text explaining where this restriction is broken.
