    • Fast and accurate CNN-based brushing in scatterplots 

      Fan, Chaoran; Hauser, Helwig (Journal article; Peer reviewed, 2018)
      Brushing plays a central role in most modern visual analytics solutions and effective and efficient techniques for data selection are key to establishing a successful human‐computer dialogue. With this paper, we address ...
    • Fast biclustering by dual parameterization 

      Drange, Pål Grønås; Reidl, Felix; Villaamil, Fernando Sánchez; Sikdar, Somnath (Conference object; Peer reviewed; Journal article, 2015)
      We study two clustering problems, Starforest Editing, the problem of adding and deleting edges to obtain a disjoint union of stars, and the generalization Bicluster Editing. We show that, in addition to being NP-hard, none ...
    • Fast Method for Maximum-Flow Problem with Minimum-Lot Sizes 

      Ganeshan, Vithya (Master thesis, 2015-03-03)
      In transportation networks, such as pipeline networks for transporting natural gas, it is often impractical to send across amounts of flow below a certain threshold. Such lower threshold is referred as the minimum-lot size. ...
    • Fast methods to solve the pooling problem 

      Kejriwal, Anisha (Master thesis, 2014-05-31)
      In pipeline transportation of natural gas, simple network flow problems are replaced by hard ones when bounds on the flow quality are imposed. The sources, typically represented by gas wells, provide flow of unequal ...
    • Faster enumeration of minimal connected dominating sets in split graphs 

      Skjørten, Ida Bredal (Master thesis, 2017-06-20)
      Graphs are mathematical objects that can be used to model many real world problems. An example is a roadmap, where the nodes in the graph represent cities and the edges of the graph represent roads. An interesting and ...
    • Filtering duplicate reads from 454 pyrosequencing data 

      Balzer, Susanne Mignon; Malde, Ketil; Grohme, Markus A.; Jonassen, Inge (Peer reviewed; Journal article, 2013)
      Motivation: Throughout the recent years, 454 pyrosequencing has emerged as an efficient alternative to traditional Sanger sequencing and is widely used in both de novo whole-genome sequencing and metagenomics. Especially ...
    • Filtering of FTLE for Visualizing Spatial Separation in Unsteady 3D Flow 

      Pobitzer, Armin; Peikert, Ronald; Fuchs, Raphael; Theisel, Holger; Hauser, Helwig (Peer reviewed; Journal article, 2012)
      In many cases, feature detection for flow visualization is structured in two phases: first candidate identification, and then filtering. With this paper, we propose to use the directional information contained in the ...
    • Finding even subgraphs even faster 

      Goyal, Prachi; Misra, Pranabendu; Panolan, Fahad; Philip, Geevarghese; Saurabh, Saket (Conference object; Peer reviewed; Journal article, 2015)
      Problems of the following kind have been the focus of much recent research in the realm of parameterized complexity: Given an input graph (digraph) on n vertices and a positive integer parameter k, find if there exist k ...
    • Finding Induced Subgraphs via Minimal Triangulations 

      Fomin, Fedor; Villanger, Yngve (Conference object; Peer reviewed; Journal article, 2010)
      Potential maximal cliques and minimal separators are combinatorial objects which were introduced and studied in the realm of minimal triangulation problems in- cluding Minimum Fill-in and Treewidth. We discover unexpected ...
    • Finding k Disjoint Triangles in an Arbitrary Graph 

      Fellows, Mike; Heggernes, Pinar; Rosamond, Frances; Sloper, Christian; Telle, Jan Arne (Conference object, 2004)
    • Finding Resource Bounds in the Presence of Explicit Deallocation 

      Truong, Anh Hoang; Bezem, Marcus A. (Journal article, 2005-10-17)
      A software program requesting a resource that is not available usually raises an out-of-resource exception. Component software is software that has been assembled from standardized, reusable components which, in turn, may ...
    • Firewalls: Enforcement of Security Policy in networks 

      Nordås, Harald (Master thesis, 2014-11-20)
      Firewalls are set up to protect computer networks. Originally, networks were just coupled together, in order to achieve connection. With the ability to reach networks all over the world, one started to denote this the ...
    • Fixed Parameter Set Splitting, Linear Kernel and Improved Running Time 

      Lokshtanov, Daniel; Sloper, Christian (2005)
    • A Fixed-Parameter Perspective on #BIS 

      Curticapean, Radu; Dell, Holger; Fomin, Fedor; Goldberg, Leslie Ann; Lapinskas, John (Peer reviewed; Journal article, 2019-07-18)
      The problem of (approximately) counting the independent sets of a bipartite graph (#BIS) is the canonical approximate counting problem that is complete in the intermediate complexity class #RHΠ1. It is believed that #BIS ...
    • Floating Fault Analysis of Trivium 

      Hojsík, Michal; Rudolf, Bohuslav (Lecture Notes in Computer Science; 5365, Chapter; Peer reviewed, 2008)
      One of the eSTREAM final portfolio ciphers is the hardwareoriented stream cipher Trivium. It is based on 3 nonlinear feedback shift registers with a linear output function. Although Trivium has attached a lot of interest, ...
    • Formulas as programs 

      Burrows, Eva (Master thesis, 2003)
      Alma-0 is a programming language supporting declarative programming, which combines the advantages of imperative and logic programming paradigms. This work explores declarative programming by extending the interpretation ...
    • FPT Algorithms for Diverse Collections of Hitting Sets 

      Baste, Julien; Jaffke, Lars; Masařík, Tomáš; Philip, Geevarghese; Rote, Günter (Peer reviewed; Journal article, 2019-11-27)
      In this work, we study the d-Hitting Set and Feedback Vertex Set problems through the paradigm of finding diverse collections of r solutions of size at most k each, which has recently been introduced to the field of ...
