This paper describes a method of dynamically searching for objects on the seabed using side-scan sonar images. Traditionally this has been a two step process where first the area is mapped and then later objects are chosen for inspection in a second pass. In the paper a model is described to explore different search tactics. Using this model we show that it can be beneficial to use an on-line detection...
Various parameters of graphs connected to sparse matrix factorization and other applications can be approximated using an algorithm of Leighton et al. that finds vertex separators of graphs. The approximate values of the parameters, which include minimum front size, treewidth, pathwidth, and minimum elimination tree height, are no more than O(log n) (minimum front size and treewidth) and O(log ...
