All three talks are listed as follows:\n<\/p>\n<ul>\n<li>\n\t\t&nbsp;S. Bagheri, W. Konen: A new repair method for constrained optimization.\n\t<\/li>\n<li>\n\t\t&nbsp;W. Konen, S. Bagheri: Common pitfalls in RBF modeling.\n\t<\/li>\n<li>\n\t\t&nbsp;S. Bagheri, W. Konen: Solving the G-problems in less than 500 iterations: Better understanding of surrogate modeling improves efficient constrained optimization.\n\t<\/li>\n<\/ul>\n<p>\n\tThe other three talks given by Dr. Emmerich (Assistant Professor at Leiden University) ,&nbsp;Hao Wang and Bas van Stein (PhD students at Leiden University)&nbsp; are as follows:\n<\/p>\n<ul>\n<li>\n\t\tM. Emmerich: From Data to Decisions: Recent Advances and Future Challenges in Multicriteria Optimization and Decision Making\n\t<\/li>\n<li>\n\t\tH. Wang: Multi-point Efficient Global Optimization using Niching Evolution Strategy\n\t<\/li>\n<li>\n\t\tB. van Stein: Cluster Kriging\n\t<\/li>\n<\/ul>\n<p>\n\tInteresting talks, lively discussions, friendly atmosphere and an active and motivated research team made last Friday very productive.&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The research group supervised by Prof.&nbsp;Wolfgang Konen from TH K&ouml;ln has a collaboration with the Natural Computing group (head: Prof. Thomas H.W.
