Economic and environmental impacts of ballast water management on Small Island Developing States and Least Developed Countries

no code implementations30 Aug 2021 Zhaojun Wang, Amanda M. Countryman, James J. Corbett, Mandana Saebi

The Gini coefficient of 0. 66 shows the inequality in risk changes relative to income levels among regions, but risk reductions across all nations vary without particularly high risks for SIDS and LDCs than for large economies.

An Automatic Design Framework of Swarm Pattern Formation based on Multi-objective Genetic Programming

no code implementations31 Oct 2019 Zhun Fan, Zhaojun Wang, Xiaomin Zhu, Bingliang Hu, Anmin Zou, Dongwei Bao

Most existing swarm pattern formation methods depend on a predefined gene regulatory network (GRN) structure that requires designers' priori knowledge, which is difficult to adapt to complex and changeable environments.

Push and Pull Search Embedded in an M2M Framework for Solving Constrained Multi-objective Optimization Problems

no code implementations2 Jun 2019 Zhun Fan, Zhaojun Wang, Wenji Li, Yutong Yuan, Yugen You, Zhi Yang, Fuzan Sun, Jie Ruan, Zhaocheng Li

In dealing with constrained multi-objective optimization problems (CMOPs), a key issue of multi-objective evolutionary algorithms (MOEAs) is to balance the convergence and diversity of working populations.

Embedding Push and Pull Search in the Framework of Differential Evolution for Solving Constrained Single-objective Optimization Problems

no code implementations16 Dec 2018 Zhun Fan, Wenji Li, Zhaojun Wang, Yutong Yuan, Fuzan Sun, Zhi Yang, Jie Ruan, Zhaocheng Li, Erik Goodman

In the top sub-population, the search process is divided into two different stages --- push and pull stages. An adaptive DE variant with three trial vector generation strategies is employed in the proposed PPS-DE.
