Constraint propagation using dominance in interval Branch & Bound for nonlinear biobjective optimization.

•We study the use of constraint propagation in interval Branch & Bound for nonlinear biobjective optimization.•In particular, we propose a generic Branch & Bound that includes state of art techniques.•We propose dominance contractors as particular constraint propagation technique for exploiting upper bound sets.•We assess the strength and weaknesses of the proposed approaches and compare them to existing literature.
