WADS alternates with the ScandinavianWorkshoponAlgorithmsTheory(SWAT),continuingthetradition of SWAT and WADS starting with SWAT 1988 and WADS 1989. Inresponsetothecallforpapers,141papersweresubmitted.Fromthesesub- missions,the ProgramCommittee selected 59papers for presentationat WADS 2011. In addition, invited lectures were given by the following distinguished re- searchers: Janos Pach, Mihai Pˇatra¸scu, and Robert E. Tarjan. The proceedings do not contain an abstract of Mihai Paˇtra¸scu’s invited lecture “Modern Data Structures”,becauseitwasunavailableatthetimeofprintingforhealthreasons. We would like to express our appreciation to the ProgramCommittee mem- bers, invited speakers, reviewers, and all authors who submitted papers.
