A geometric constraint.
Geometric constraints takes a precedence relationship between blocks and forces that the second -"From"- block must be extracted at most \(\Delta\) periods after the first -"To"- block. A Geometric Constraint is always bound to a set of horizontal precedences (RampPrecedence object).
| delphos::GeometricConstraint::GeometricConstraint | ( | const string & | name, |
| const delphos::RampPrecedence & | rprec, | ||
| const unsigned int | delta | ||
| ) |
Creates a new geometric constraint.
| name | The name of the precedence constraint. |
| rprec | The ramp precedence object. |
| delta | The maximum time difference between the extraction of blocks. |
This method creates a new geometric constraint, which is given by a ramp precedence object (already computed), a name within the instance and the maximum time difference between the blocks. Clearly, \(\Delta \in \{1,\ldots,T\}\) , where \(T\) is the horizon of the objective SchedulingInstance that will contain the constraint.

virtual |
Checks if the constraint is satisfied.
| sch | The schedule to be checked. |
Returns true only if the constraint is satisfied.
Reimplemented from delphos::PrecedenceConstraint.
|
virtual |
Checks if the given fractional schedule satisfies the constraint.
| fsch | The fractional schedule to be checked. |
This method checks if the given schedule satisfies the constraint (returning true) or not (returning false).
Reimplemented from delphos::PrecedenceConstraint.
|
virtual |
Returns the precedence object associated to the constraint.
Returns the precedence object -inside the RampPrecedence- associated to the constraint.
Reimplemented from delphos::PrecedenceConstraint.
| const unsigned int delphos::GeometricConstraint::GetTimeDifference | ( | ) | const |
Returns the constraint's extraction time difference.
Returns the constraint's extraction time difference.
