Approximation and online algorithms are fundamental tools to deal with computationally hard problems and problems in which the input is gradually disclosed over time. Both kinds of problems have a large number of applications, arising from a variety of fields.
September 8-9 Saarbrücken, Germany
9th Workshop on Approximation
and Online Algorithms
The workshop focuses on the design and analysis of approximation and online algorithms. It also covers experimental methods used to design and analyze efficient approximation and online algorithms. WAOA 2010 will be part of ALGO 2011, which also hosts ESA, ATMOS, WABI, IPEC, and ALGOSENSORS. ALGO 2011 will take place 5-9 September 2011 in Saarbruecken, Germany.
Papers are solicited in all research areas related to approximation and online algorithms, including, but not limited to:
• algorithmic game theory
• approximation classes
• coloring and partitioning
• competitive analysis
• computational finance
• cuts and connectivity
• geometric problems
• graph algorithms
• inapproximability results
• mechanism design
• network design
• packing and covering
• paradigms for the design and analysis of approximation and online
• parameterized complexity
• randomization techniques
• real-world applications
• scheduling problems
Proceedings will be published after the workshop takes place in the Springer series Lecture Notes in Computer Science. Instructions for authors can be found at
Selected papers from the workshop will be published in a special issue of Theory of Computing Systems.
Authors are invited to submit an extended abstract or full paper of at most 12 pages describing original unpublished research. Simultaneous submission to other conferences with published proceedings is not permitted. The title
page of the submission should include the authors' full names, addresses, e-mail addresses, and an abstract summarizing the results in roughly 100-200 words; the remainder of the submission should contain a description of the main results and an explanation of their importance. The submission must include a full proof of the results, part of which can be placed in the appendix, whose length is not constrained.
Papers must be submitted electronically at
The submission must be received by 23:59 (GMT) on June 22, 2011. Each accepted paper must be presented at the workshop by one of the authors.
