报告摘要: This talk studies generalized semi-infinite programs (GSIPs) given by polynomials. We propose a hierarchy of 

polynomial optimization relaxations to solve them. They are based on polynomial extensions. Then we studies GSIPs def-

ined with polyhedral parameter sets. We propose a new approach to solve them as a disjunctive program. This approach 

is based on the KKT conditions and partial Lagrange multiplier expressions. We checked its efficiency in gemstone cut-

ting applications. For SIPs with non-semialgebraic parameter sets, we studied Positivstellensätze and moment problems 

defined on the feasible sets to solve the SIPs.
