  Complexity and expressive power of weakly well-designed SPARQL
Kaminski M., Kostylev E. Theory of Computing Systems 62(4): 772-809, 2018.  Type: Article

The resource description framework (RDF) is a data model standard for the web that represents linked data as subject-predicate-object triples. Such triples can be naturally represented as labeled directed graphs. SPARQL is a query lang...

  On the uniform computational content of computability theory
Brattka V., Hendtlass M., Kreuzer A. Theory of Computing Systems 61(4): 1376-1426, 2017.  Type: Article

Weihrauch reducibility (≤W) is a type of reducibility relation that can be used to classify the uniform computational content of various mathematical objects. It is first defined for multivalued functions between s...

  The complexity of the list homomorphism problem for graphs
Egri L., Krokhin A., Larose B., Tesson P. Theory of Computing Systems 51(2): 143-178, 2012.  Type: Article

Homomorphisms are very useful in combinatorial problems in mapping and assignments. Homomorphism problems involve greater modeling power than graph coloring, yet compared to general constraint satisfaction problems (CSPs), they are sim...

  Proofs, programs, processes
Berger U., Seisenberger M. Theory of Computing Systems 51(3): 313-329, 2012.  Type: Article

Ensuring that the implementation of a program meets its specification is one of the long-running goals of computer science. Approaches to the problem can be divided into two main branches: program verification and program generation. I...

  Classification of computably approximable real numbers
Zheng X. Theory of Computing Systems 43(3): 603-624, 2008.  Type: Article

Real numbers can be represented mathematically in several equivalent ways, but these representations are not equivalent when they are used to compute real numbers and real functions. Although all representations yield computable real n...

  The effect of faults on network expansion
Bagchi A., Bhargava A., Chaudhary A., Eppstein D., Scheideler C. Theory of Computing Systems 39(6): 903-928, 2006.  Type: Article

Faults are a normal aspect of network operations--indeed, they are commonplace and expected in mobile networks. The authors study the problem of how resilient networks are to node faults. They focus on how many faults a networ...
