Variable-depth adaptive large meighbourhood search algorithm for Open Periodic Vehicle Routing Problem with time windows (2017)
Presentation / Conference Contribution
Chen, B., Qu, R., & Ishibuchi, H. (2017). Variable-depth adaptive large meighbourhood search algorithm for Open Periodic Vehicle Routing Problem with time windows.

The Open Periodic Vehicle Routing Problem with Time Windows (OPVRPTW) is a practical transportation routing and scheduling problem arising from real-world scenarios. It shares some common features with some classic VRP variants. The problem has a tig...

Information core optimization using Evolutionary Algorithm with Elite Population in recommender systems (2017)
Presentation / Conference Contribution
Mu, C., Cheng, H., Feng, W., Liu, Y., & Qu, R. (2017). Information core optimization using Evolutionary Algorithm with Elite Population in recommender systems.

Recommender system (RS) plays an important role in helping users find the information they are interested in and providing accurate personality recommendation. It has been found that among all the users, there are some user groups called “core users”...

Change detection in SAR images based on the salient map guidance and an accelerated genetic algorithm (2017)
Presentation / Conference Contribution
Mu, C., Li, C., Liu, Y., Sun, M., Jiao, L., & Qu, R. (2017). Change detection in SAR images based on the salient map guidance and an accelerated genetic algorithm. In 2017 IEEE Congress on Evolutionary Computation (CEC) - Proceedings (1150-1157). https://doi.org/10.1109/CEC.2017.7969436

This paper proposes a change detection algorithm in synthetic aperture radar (SAR) images based on the salient image guidance and an accelerated genetic algorithm (S-aGA). The difference image is first generated by logarithm ratio operator based on t...

A hybrid EDA for load balancing in multicast with network coding (2017)
Journal Article

Load balancing is one of the most important issues in the practical deployment of multicast with network coding. However, this issue has received little research attention. This paper studies how traffic load of network coding based multicast (NCM) i... Read More about A hybrid EDA for load balancing in multicast with network coding.

An improved MOEA/D algorithm for multi-objective multicast routing with network coding (2017)
Journal Article

Network coding enables higher network throughput, more balanced traffic, and securer data transmission. However, complicated mathematical operations incur when packets are combined at intermediate nodes, which, if not operated properly, lead to very...

Mean-VaR portfolio optimization: a nonparametric approach (2017)
Journal Article
Lwin, K. T., Qu, R., & MacCarthy, B. L. (2017). Mean-VaR portfolio optimization: a nonparametric approach. European Journal of Operational Research, 260(2), https://doi.org/10.1016/j.ejor.2017.01.005

Portfolio optimization involves the optimal assignment of limited capital to different available financial assets to achieve a reasonable trade-off between profit and risk. We consider an alternative Markowitz's mean-variance model, in which the vari... Read More about Mean-VaR portfolio optimization: a nonparametric approach.
