Наслов предавања: ON FINDING WELL SPREAD NON-DOMINATED VECTORS TO MANY-OBJECTIVE NONLINEAR OPTIMIZATION PROBLEMS

Апстракт:
In this talk a recent approach to generate well spread non-dominated vectors to a many-objective nonlinear optimization problem will be described. The approach employs an optimization model designed to yield certain non-dominated vectors that can fill gaps between already generated non-dominated vectors, providing a way to deal with the adjacency of generated non-dominated vectors and to quantify the gaps between them. A pseudo-randomized variant of the exact approach will be also presented. Ten problems from the literature, including bi-objective, 3-objective, 5-objective and 10-objective test instances with non-convex, disconnected or continuous Pareto frontier were selected for illustration. The inverted generational distance (IGD) and the hyper-volume (HV) were used as performance metrics to measure the quality of the obtained approximations.

The presentation is based on a joint work with prof. Fred Glover, University of Colorado.
