A finite element method for Dirichlet boundary control problems governed by parabolic PDEs
Wei Gong, Michael Hinze, Zhaojie Zhou
Finite element approximations of Dirichlet boundary control problems governed by parabolic PDEs on convex polygonal domains are studied in this paper. The existence of a unique sol…
Computing the Least-core and Nucleolus for Threshold Cardinality Matching Games
Qizhi Fang, Bo Li, Xiaoming Sun +2
Cooperative games provide a framework for fair and stable profit allocation in multi-agent systems. \emph{Core}, \emph{least-core} and \emph{nucleolus} are such solution concepts t…
Collective credit allocation in science
Hua-Wei Shen, Albert-László Barabási
Collaboration among researchers is an essential component of the modern scientific enterprise, playing a particularly important role in multidisciplinary research. However, we cont…
Finding representative sets of optimizations for adaptive multiversioning applications
Lianjie Luo, Yang Chen, Chengyong Wu +2
Iterative compilation is a widely adopted technique to optimize programs for different constraints such as performance, code size and power consumption in rapidly evolving hardware…
DualTable: A Hybrid Storage Model for Update Optimization in Hive
Songlin Hu, Wantao Liu, Tilmann Rabl +6
Hive is the most mature and prevalent data warehouse tool providing SQL-like interface in the Hadoop ecosystem. It is successfully used in many Internet companies and shows its val…
Micro-transition cascades to percolation
Wei Chen, Malte Schröder, Raissa M. D'Souza +2
We report the discovery of a discrete hierarchy of micro-transitions occurring in models of continuous and discontinuous percolation. The precursory micro-transitions allow us to t…
