JAMA is a basic linear algebra package for Java. It provides user-level classes for constructing and manipulating real, dense matrices. It is meant to provide sufficient functionality for routine problems, packaged in a way that is natural and understanda
We present the Priority R-tree, or PR-tree, which is the first R-tree variant that always answers a window query using O((N/B)1-1/d+T/B) I/Os, where N is the number of d-dimensional (hyper-) rectangles stored in the R-tree, B is the disk block size, and T
Dijkstra's algorithm is probably the best-known and thus most implemented shortest path algorithm. It is simple, easy to understand and implement, yet impressively efficient. By getting familiar with such a sharp tool, a developer can solve efficiently an
