An n-node tree has to be explored by a group of k mobile robots deployed initially at the root. Robots traverse the edges of the tree until all nodes are visited. We would like to ...

We consider the use of a static context tree for binary image compression. The contexts are stored in the leaves of a variable-depth binary tree. The tree structure itself is full...

Abstract. Trees are useful data structures, but to design efficient parallel programs over trees is known to be more difficult than to do over lists. Although several important tre...
