    Chebyshev approximation of the null function by an affine combination of complex exponential functions
    Download  www.optimization-online.org
    We describe the theoretical solution of an approximation problem that uses a finite weighted sum of complex exponential functions. The problem arises in an optimization model for t...

    Convergence analysis of the Jacobi spectral-collocation methods for Volterra integral equations with a weakly singular kernel
    Download  www.math.hkbu.edu.hk
    In this paper, a Jacobi-collocation spectral method is developed for Volterra integral equations of the second kind with a weakly singular kernel. We use some function transformati...

    On the practical complexity of solving the maximum weighted independent set problem for optimal scheduling in wireless networks
    Download  udelmodels.eecis.udel.edu
    It is well known that the maximum weighted independent set (MWIS) problem is NP-complete. Moreover, optimal scheduling in wireless networks requires solving a MWIS problem. Conseq...

    Approximation Algorithms for the Graph Orientation Minimizing the Maximum Weighted Outdegree
    Download  www.df.lth.se
    Given an undirected graph G = (V, E) and a weight function w : E → Z+ , we consider the problem of orienting all edges in E so that the maximum weighted outdegree among all verti...
