Algorithm Engineering for Route Planning – An Update –icular, new theoretical insights on when and why those techniques work so well will be discussed. The main part of the talk will focus on variants of the problem that occur in more realistic traffic scenarios.

Improved Approximations for Buy-at-Bulk and Shallow-Light ,-Steiner Trees and (,,2)-Subgraph.(log..),.(log.))-approximation for SL.ST: the algorithm finds a .-Steiner tree of diameter at most .(.·log.) whose cost is at most . where . is the cost of an LP relaxation of the problem. This improves on the algorithm of with ratio (.(log..), .(log..)). Using this, we obtain an .(log..)-appro

Path Queries in Weighted Treestructure can also support path reporting queries in . time, where . is the size of output. In addition, we present a data structure that answers path reporting queries in . time, using . space. These are the first data structures that answer path reporting queries.
