This paper proposes a method for improving genetic algorithm in traveling salesman problems. k-Means clustering is applied to group nodes in the problems. Then, genetic algorithms are applied for each cluster. An important step in the proposed algorithm is the connection of clusters. We propose a...

哈尔滨工业大学工学硕士学位论文 摘要 众所周知,K-means聚类是数据挖掘中非常经典和常用的方法之一,它通过计 算数据项之间的距离可以把相似的数据项聚集在一起。随着信息化、数字化、网络 化进程加速,经济全球化已成为一种不可逆的趋势,聚类算法中的数据来源越来越 多样化,数据安全越来越重要。考虑到数据会来自多个参...
A lot of effort has been made to solve such kind of problems, but a mixed integer linear programming formulation (MILP) is still missing. In this paper, we formulate MILP models. The advantage of MILP formulation is that users can extend the original problem with arbitrary linear constraints....

In many papers, the authors either show different problems requiring solutions by periodic-oriented clustering methods or they attempt to propose new solutions, often attempting to improve the computational complexities of existing techniques Ṗeriodic clustering usage involves a spatial–temporal pattern ...
Clustering is a very popular machine-learning technique that is often used in data exploration of continuous variables. In general, there are two problems commonly encountered in clustering: (1) the selection of the optimal number of clusters, and (2) th
Ensemble clustering has emerged as an important elaboration of the classical clustering problems. Ensemble clustering refers to the situation in which a nu... Z Li,L Tao,CHQ Ding - IEEE 被引量: 43发表: 2011年 A hierarchical fuzzy cluster ensemble approach and its application to big data clust...

But for comprehensive assessments that start with outcomes, there are problems when developing a vulnerability assessment system for earthen sites, such as the difficulty in selecting evaluation indicators and the complexity of relationships that are difficult to clarify. With the rapid development of art...
