Chebychev scalarization problem
WebThis paper studies multi-objective optimization problems that are given by polynomial functions. First, we study the convex geometry for (weakly) Pareto values and give a convex representation for them. Linear scalarization problems (LSPs) and Chebyshev scalarization problems (CSPs) are typical approaches for getting (weakly) Pareto points. WebNov 29, 2024 · The augmented weighted Chebyshev scalar problem, formulated by adding an augmented l_1- norm term to the objective function of the weighted Chebyshev scalarization method, suggested by Steuer and Choo (see [ 5 ]), is shown to generate properly efficient solutions for appropriately selected values of weights and augmentation …

WebEarly works on scalarization include heuristic-based al-gorithms such as ParEgo (Knowles,2006) and MOEAD (Zhang & Li,2007). The most popular scalarizations are the linear scalarization s (y) = P i iy iand the Cheby-shev scalarization s (y) = min i i(y i z i) for some refer-ence point zand some distribution over (Nakayama et al., 2009). WebMar 6, 2024 · Fortunately, we find that this problem can be easily solved by using the Chebyshev scalarization function in multi-objective reinforcement learning (RL). In this paper, we propose a VM placement algorithm based on multi-objective RL (VMPMORL). VMPMORL is designed based on the Chebyshev scalarization function.
Webtion problems related to the BOIP, called scalarization problems (or simply, scalarizations). A scalarization is formulated by means of a real-valued scalarizing function of the objective functions of the BOIP, auxiliary scalar or vector variables and/or parameters ([7]). All authors contributed equally to this work. WebOct 23, 2024 · Reinforcement learning based on the Chebyshev scalarization function is a new framework, which is effective in solving the weight selection problem. Therefore, we design EnMORL based on it. Our goal is to minimize the makespan and energy consumption of the workflow.
