Efficient graphlet kernels for large graph comparison
TLDR
We propose to compare graphs by counting graphlets, i.e., subgraphs with k nodes where k ∈ {3, 4, 5}. Expand

Faster algorithms for the shortest path problem
Efficient implementations of Dijkstra's shortest path algorithm are investigated. A new data structure, called the <italic>radix heap</italic>, is proposed for use in this algorithm. On a networkExpand

Popular matchings
TLDR
In this paper, we give the first polynomial-time algorithms to determine if an instance admits a popular matching, and to find a largest such matching, if one exists, and show that the problem has equivalent time complexity to the maximum-cardinality bipartite matching problem. Expand

Congruence, similarity, and symmetries of geometric objects
TLDR
We consider the problem of computing geometric transformations (rotation, translation, reflexion) that map a point setA exactly or approximately into a pointSet B, and derive efficient algorithms for various cases. Expand
