===================================================================== Technion Seminar in Nonlinear Analysis and Optimization Speaker: Aviv Gibali Fraunhofer Institute, Kaiserslautern Title: Navigation and Decision-Making in Multicriteria Optimization for Intensity-Modulated Radiation Therapy Treatment Planning Time: Sunday, December 30, 2012, at 14:30 Place: Room 814, Amado Mathematics Building Abstract: <http://www.math.technion.ac.il/~techm/temp/20121230GIBA.pdf> Or read it here: Multicriteria Optimization (MCO) Problems are problems that involve several optimization criteria and it is possible that these criteria can contradict each other. Cancer radiotherapy treatment is one example, where we wish to maximize the amount of cancer tissue exposed to radiation treatment while minimizing radiation exposure of healthy organs and, clearly, there is no easy compromise between both criteria. Since, in general there exists no feasible solution that optimizes all criteria, the goal is to find solutions ("efficient solutions") in which no criteria can be improved without worsening any other criteria. Finally, the Decision-Maker chooses a decision based on the information obtained concerning the "efficient solutions". Our research is focused on generating and navigating solutions, that is, exploring different possibilities and their respective compromises in order to support the Decision-Maker in his choice. ====================================================================== Technion Math.
