Post-pareto Analysis for Multiobjective Parabolic Control Systems
In this paper is presented the problem of optimizing a functional over a Pareto control set associated with a convex multiobjective control problem in Hilbert spaces, namely parabolic system. This approach generalizes for this setting some results obtained in finite dimensions. Some examples are presented. General optimality results are obtained, and a special attention is paid to the linear-qu...
متن کاملPreference Dominance Approaches for Conversational Recommender Systems
Conversational recommender systems typically involve iteratively showing the user a small set of options for them to choose between. In order to choose an appropriate set to display at each stage, it is useful to have information regarding the user’s relative preference between options: specifically whether an option is dominated by others with respect to the user’s preference relation. This pa...
متن کاملAsymmetric Pareto-adaptive Scheme for Multiobjective Optimization
A core challenge ofMultiobjective Evolutionary Algorithms (MOEAs) is to attain evenly distributed Pareto optimal solutions along the Pareto front. In this paper, we propose a novel asymmetric Pareto-adaptive (apa) scheme for the identification of well distributed Pareto optimal solutions based on the geometrical characteristics of the Pareto front. The apa scheme applies to problem with symmetr...
متن کاملPareto-Based Multiobjective AI Planning
Real-world problems generally involve several antagonistic objectives, like quality and cost for design problems, or makespan and cost for planning problems. The only approaches to multiobjective AI Planning rely on metrics, that can incorporate several objectives in some linear combinations, and metric sensitive planners, that are able to give different plans for different metrics, and hence t...
متن کاملSequence - based Approaches to Course Recommender Systems
A curriculum is a planned sequence of instructions or a view of the student’s experiences in terms of the educator’s or school’s instructional goals. However, the guidance provided by the curriculum is limited and both student and course counsellor struggle with the question of choosing a suitable course at a proper time. Many researchers have focused on making course recommendations with tradi...
