PhD student Anders Skjäl was invited to visit Professor Christodoulos Floudas’ research group in Princeton University, USA, for the period 28.3–8.4 2011. Professor Floudas is a member of the International Scientific Panel of the OSE group and was the plenary speaker at the annual OSE seminar in 2010. As a result of the research visit, progress has been made on a nondiagonal version of the aBB underestimator for nonconvex optimization.
