Interior point filter method for semi-infinite programming problems. Optimization. ISSN 0233-1934. 60:10-11, p. 1309-1338.http://hdl.handle.net/10198/7531Semi-infinite programming (SIP) problems can be efficiently solved by reduction-type methods. Here, we present a new reduction method for SIP, where the multi-local optimization is carried out with a stretched simulated annealing algorithm, the reduced (finite) problem is approximately solved by a Newton’s primal–dual interior point method that uses a novel twodimensional filter line search strategy to guarantee the convergence to a KKT point that is a minimizer, and the global convergence of the overall reduction method is promoted through the implementation of a classical two-dimensional filter line search. Numerical experiments with a set of well-known problems are shown.engNonlinear optimizationSemi-infinite programmingInterior point methodFilter methodLine search techniquejournal article10.1080/02331934.2011.616894
