Member Function Documentation

◆ post()

ExecStatus Gecode::Int::Arithmetic::MultDom::post ( Home home,
IntView x0,
IntView x1,
IntView x2 )
static

Post propagator $x_0\cdot x_1=x_2$.

Definition at line 311 of file mult.cpp.

◆ copy()

Actor * Gecode::Int::Arithmetic::MultDom::copy ( Space & home)
virtual

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 197 of file mult.cpp.

◆ cost()

PropCost Gecode::Int::Arithmetic::MultDom::cost ( const Space & home,
const ModEventDelta & med ) const
virtual

Cost function.

If in stage for bounds propagation, the cost is low ternary. Otherwise it is high ternary.

Reimplemented from Gecode::TernaryPropagator< IntView, PC_INT_DOM >.

Definition at line 202 of file mult.cpp.

◆ propagate()

ExecStatus Gecode::Int::Arithmetic::MultDom::propagate ( Space & home,
const ModEventDelta & med )
virtual

Perform propagation.

Implements Gecode::Propagator.
