Efficient algorithms for shortest path queries in planar digraphs,f constant treewidth. We describe efficient algorithms for this problem for any class of digraphs for which an . separator theorem holds. For such graphs our algorithm uses . space and answers queries in ../. time, for any previously chosen . ∃ [..]. For the class of planar digraphs improved algorithms are described.

Improved approximations of independent dominating set in bounded degree graphs, .-regular graphs, for . ≥ 4. In particular, the greedy phase proposed for at most cubic graphs is extended to any . and iteratively repeated until the degree of the remaining graph is greater than 3. Finally, the algorithm for at most cubic graphs is executed..Our algorithms achieve approximation ratios:

Detecting diamond necklaces in labeled dags,ssical patterns encountered in distributed debugging. Then an efficient polynomial time algorithm detecting such patterns in a labeled dag is presented. To be easily adapted to an on-the-fly detection of the pattern in distributed executions, the algorithm visits the nodes of the graph according to a topological sort strategy.
