20.500.12556/DKUM-93322 Constrained multi-objective optimization of simulated tree pruning with heterogeneous criteria Virtual pruning of simulated fruit tree models is a useful functionality provided by software tools for computer-aided horticultural education and research. It also enables algorithmic pruning optimization with respect to a set of quantitative objectives, which is important for analytical purposes and potential applications in automated pruning. However, the existing studies in pruning optimization focus on a single type of objective, such as light distribution within the crown. In this paper, we propose the use of heterogeneous objectives for discrete multi-objective optimization of simulated tree pruning. In particular, the average light intake, crown shape, and tree balance are used to observe the emergence of different pruning patterns in the non-dominated solution sets. We also propose the use of independent constraint objectives as a new mechanism to confine overfitting of solutions to individual pruning criteria. Finally, we perform the comparison of NSGA-II, SPEA2, and MOEA/D-EAM on this task. The results demonstrate that SPEA2 and MOEA/D-EAM, which use external solution archives, can produce better sets of non-dominated solutions than NSGA-II. multi-objective optimization virtual tree pruning heterogeneous objectives constraint objectives NSGA-II SPEA2 EuMOEA/D-EAM večobjektna optimizacija objektivnost heterogena objektivnost true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/applsci © 2021 by the authors Članek v reviji 2025-06-19 09:20:26 2025-06-19 09:20:26 2025-06-20 03:12:17 0000-00-00 00:00:00 2021 0 0 18 str. iss. 22 Vol. 11 15 Nov. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2021-09-25 2021-11-10 2021-11-15 004.5 86459907 10.3390/app112210781 2076-3417 applsci-11-10781.pdf applsci-11-10781.pdf 1 8E7C94409C3B9E0A8FE7B3DCAAAD4F63 d47562973d30c696aa24247c1ba2be2f4650008dc872e773f17c4fb2b26c0863 18185d94-4cde-11f0-b77e-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=192440 https://www.mdpi.com/2076-3417/11/22/10781 0 1d3ccba6-4cde-11f0-b77e-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=192441 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
