Dec 15 2014   Search methods for tile sets in patterned DNA self-assembly Göös M., Lempiäinen T., Czeizler E., Orponen P. Journal of Computer and System Sciences 80(1): 297-319, 2014.  Type: Article A very important area of nanotechnology--self-assembly--is addressed in this paper. It considers several algorithmic approaches (exhaustive branch and bound, heuristics with some relaxed objectives, and answer set pro... Sep 11 2014   The hardness of counting full words compatible with partial words Manea F., Tiseanu C. Journal of Computer and System Sciences 79(1): 7-22, 2013.  Type: Article Sequences of symbols from a given alphabet are known as words. If symbols are unknown at some positions, then such sequences are known as partial words. Two partial words are said to be compatible when they agree in all positions where... Apr 22 2014   Parameterized complexity of connected even/odd subgraph problems Fomin F., Golovach P. Journal of Computer and System Sciences 80(1): 157-179, 2014.  Type: Article The notion of fixed parameter tractability involves relaxed polynomial-time complexity, which admits algorithms whose runtimes are exponential, but only in terms of some parameter that is expected to be small. More formally, a problem ... Jan 2 2014   Trustworthiness analysis of sensor data in cyber-physical systems Tang L., Yu X., Kim S., Gu Q., Koutra D., Leung A., La Porta T. Journal of Computer and System Sciences 79(3): 383-401, 2013.  Type: Article A cyber-physical system (CPS) is the large-scale global integration of distributed sensing systems. With the growing importance of and need for CPS applications, a number of research challenges need to be solved. One such problem invol... Jul 31 2013   Synonymous theories and knowledge representations in answer set programming Pearce D., Valverde A. Journal of Computer and System Sciences 78(1): 86-104, 2012.  Type: Article The problem of determining the equivalence of knowledge descriptions (logical theories, ontologies, programs, databases, and so on) is an important one, not only in core knowledge representation and reasoning topics, but also in many e... Feb 13 2013    Cloud federation in a layered service model Villegas D., Bobroff N., Rodero I., Delgado J., Liu Y., Devarakonda A., Fong L., Masoud Sadjadi S., Parashar M. Journal of Computer and System Sciences 78(5): 1330-1344, 2012.  Type: Article In this paper, Villegas et al. tackle the problem of federating different cloud infrastructures (with the same service interfaces) by leveraging a layered service model. The layers are those defined by the National Institute of Standar... Jan 3 2013   On bounded block decomposition problems for under-specified systems of equations Bomhoff M., Kern W., Still G. Journal of Computer and System Sciences 78(1): 336-347, 2012.  Type: Article Consider a set of equations (not necessarily linear) with several unknowns, which is not over-determined. We could, of course, solve the whole set; however, it might be possible to solve a subset, plug the values thus obtained into the... Apr 26 2012   Computing optimal outcomes under an expressive representation of settings with externalities Conitzer V., Sandholm T. Journal of Computer and System Sciences 78(1): 2-14, 2012.  Type: Article Computing optimal allocations is a ubiquitous and notoriously hard computational problem that is significant in settings such as combinatorial auctions. This paper considers an expressive representation of such settings in which agents... Apr 19 2012   Accurate and precise aggregation counting Preparata F. Journal of Computer and System Sciences 78(1): 192-197, 2012.  Type: Article It was a struggle writing this review--not because the paper was difficult to comprehend, but because it was so succinct. In fact, it would be hard to convey the information presented in fewer words. As such, my summary risks ... Mar 22 2012       Display 510152550100 per column
