STSP seeks a pair of pickup and delivery tours in two distinct networks, where the two tours are related by LIFO contraints. We address here the problem approximability. We notabl...
: We investigate architectural properties required for supporting automatic service composition. First, composable service architecture will be described, based on modeling Web ser...
This paper critically analyzes reduct construction methods evels. At a high level, one can abstract commonalities from the existing algorithms, and classify them into three basic g...
This short note considers the problem of point location in a Delaunay triangulation of n random points, using no additional preprocessing or storage other than a standard data stru...
