  text: "The unit cost model is both convenient and largely realistic for describing\r\ninteger
    decision algorithms over (+,*). Additional operations like division\r\nwith remainder
    or bitwise conjunction, although equally supported by computing\r\nhardware, may
    lead to a considerable drop in complexity. We show a variety of\r\nconcrete problems
    to benefit from such NON-arithmetic primitives by presenting\r\nand analyzing
    corresponding fast algorithms."

  text: "The validation of material flow models as well as the selection of promising
    strategies for the generation of a successful experiment plan is a time-consuming
    process. A new approach is presented, which supports the simulation expert in
    his working process by giving him the opportunity to modify the simulated simulation
    run and afterwards compare the effects of his modification with the original setting,
    online and in one user interface, implemented by switching the visualizations
    between the simulation runs or opening up to 5 parallel 3D windows. The method
    developed therefore clones existing simulation runs online and allows the navigation
    within these existing simulation runs. The method has been implemented and is
    validated by a test model, which describes in detail the new working process of
    a modeler. New research questions are derived from this work, which will define
    following working steps.\r\n"

  text: "We present random sampling algorithms that with probability at least 1 − δ
    compute a (1 ±ε)-approximation of the clustering coefficient and of the number
    of bipartite clique subgraphs of a graph given as an incidence stream of edges.
    The space used by our algorithm to estimate the clustering coefficient is inversely
    related to the clustering coefficient of the network itself. The space used by
    our algorithm to compute the number K 3,3 of bipartite cliques is proportional
    to the ratio between the number of K 1,3 and K 3,3 in the graph.\r\n\r\nSince
    the space complexity depends only on the structure of the input graph and not
    on the number of nodes, our algorithms scale very well with increasing graph size.
    Therefore they provide a basic tool to analyze the structure of dense clusters
    in large graphs and have many applications in the discovery of web communities,
    the analysis of the structure of large social networks and the probing of frequent
    patterns in large graphs.\r\n\r\nWe implemented both algorithms and evaluated
    their performance on networks from different application domains and of different
    size; The largest instance is a webgraph consisting of more than 135 million nodes
    and 1 billion edges. Both algorithms compute accurate results in reasonable time
    on the tested instances."

  text: We study graph properties which are testable for bounded degree graphs in
    time independent of the input size. Our goal is to distinguish between graphs
    having a predetermined graph property and graphs that are far from every graph
    having that property. It is believed that almost all, even very simple graph properties
    require a large complexity to be tested for arbitrary (bounded degree) graphs.
    Therefore in this paper we focus our attention on testing graph properties for
    special classes of graphs. We call a graph family non-expanding if every graph
    in this family is not a weak expander (its expansion is O(1/log2 n), where n is
    the graph size). A graph family is hereditary if it is closed under vertex removal.
    Similarly, a graph property is hereditary if it is closed under vertex removal.
    Next, we call a graph property Π to be testable for a graph family F if for every
    graph G ε F, in time independent of the size of G we can distinguish between the
    case when G satisfies property Π and when it is far from every graph satisfying
    property Π. In this paper we prove thatIn the bounded degree graph model, any
    hereditary property is testable if the input graph belongs to a hereditary and
    non-expanding family of graphs.As an application, our result implies that, for
    example, any hereditary property (e.g., k-colorability, H-freeness, etc.) is testable
    in the bounded degree graph model for planar graphs, graphs with bounded genus,
    interval graphs, etc. No such results have been known before and prior to our
    work, in the bounded degree graph model very few graph properties have been known
    to be testable for any graph classes.

  text: In the StrSort model [2], the input is given as a stream, e.g. a sequence
    of points, and an algorithm can perform (a) streaming and (b) sorting passes to
    process the stream. A streaming pass reads the input stream from left to right
    and writes an output stream, which is the input of the next pass. A sorting pass
    is a black box operation that sorts a stream according to some partial order.
    In this paper, we develop algorithms for two basic geometric problems in the StrSort
    model. At first, we propose a divide-and-conquer algorithm that computes the convex
    hull of a point set in 2D in O(log2 n) passes using O(1) memory. Then we give
    a StrSort algorithm to compute a (1+ε)-spanner for a point set in Rd for constant
    d and constant epsilon that uses O(logd-1 n) passes and O(log n) space. This result
    implies a (1+ε)-approximation of the Euclidean minimum spanning tree in Rd, for
    constant d and ε.

  text: 'We present a novel analysis of a random sampling approach for four clustering
    problems in metric spaces: k-median, k-means, min-sum k-clustering, and balanced
    k-median. For all these problems, we consider the following simple sampling scheme:
    select a small sample set of input points uniformly at random and then run some
    approximation algorithm on this sample set to compute an approximation of the
    best possible clustering of this set. Our main technical contribution is a significantly
    strengthened analysis of the approximation guarantee by this scheme for the clustering
    problems.The main motivation behind our analyses was to design sublinear-time
    algorithms for clustering problems. Our second contribution is the development
    of new approximation algorithms for the aforementioned clustering problems. Using
    our random sampling approach, we obtain for these problems the first time approximation
    algorithms that have running time independent of the input size, and depending
    on k and the diameter of the metric space only. © 2006 Wiley Periodicals, Inc.

  text: We present a randomized block-level storage virtualization for arbitrary heterogeneous
    storage systems that can distribute data in a fair and redundant way and can adapt
    this distribution in an efficient way as storage devices enter or leave the system.
    More precisely, our virtualization strategies can distribute a set of data blocks
    among a set of storage devices of arbitrary non-uniform capacities so that a storage
    device representing x% of the capacity in the system will get x% of the data (as
    long as this is in principle possible) and the different copies of each data block
    are stored so that no two copies of a data block are located in the same device.
    Achieving these two properties is not easy, and no virtualization strategy has
    been presented so far that has been formally shown to satisfy fairness and redundancy
    while being time- and space-eflcient and allowing an efficient adaptation to a
    changing set of devices.

  text: We consider the problem of exploring an unknown environment using a swarm
    of autonomous robots with collective behavior emerging from their local rules.
    Each robot has only a very restricted view on the environment which makes cooperation
    difficult. We introduce a software system which is capable of simulating a large
    number of such robots (e.g. 1000) on highly complex terrains with millions of
    obstacles. Its main purpose is to easily integrate and evaluate any kind of algorithm
    for controlling the robot behavior. The simulation may be observed in real-time
    via a visualization that displays both the individual and the collective progress
    of the robots. We present the system design, its main features and underlying
    concepts.
