The hexagon and heptagon with unit diameter and maximum sum of Euclidean distances between vertices are determined by enumerating diameter configurations, an...
BibTeX referenceMinimizing the Peak Load in a Shared Storage System Based on the Duration-of-Stay of Unit Loads
The peak load is the maximum daily processing capacity requirement in a warehouse, and is an alternative criterion for the storage location assignment proble...

In this paper we present a simple technique that uses background information to improve mining the frequent patterns of structured data. This technique uses ...
BibTeX referenceSyGMA: Reducing Symmetry in Graph Mining
While recent algorithms for mining the frequent subgraphs of a database are efficient in the general case, these algorithms tend to do poorly on databases th...
