On Continuous Spatial Skyline Queries over a Line Segmentconstraint of .. We propose two methods to solve the problem. In the first method, we find some special location points which partition . into sub-segments and also make the skylines in the adjacent sub-segments different. In the second method, we apply some properties to identify data points which

A Memory-Efficient Tree Edit Distance Algorithmin memory bottleneck. We show the correctness of our approach and prove an upper bound for the memory usage. Our empirical evaluation confirms the low memory requirements and shows that in practice our algorithm performs better than the analytic guarantees suggest.

The symbolic viewpoint is about denying a model/data level divide. We discuss sustainable constraint writing with respect to further issues in con

The Political Economy of the USSRm random sampling of a rooted subtree with prescribed weight is unfortunately intractable. However, we are able to identify several practical cases that are tractable. The first case is uniform random sampling of a rooted subtree with prescribed size; the second case restricts to binary weights. For
