Given a large set of scattered points in the plane, we describe a new and efficient algorithm to find, for each point, the subset of p closest points, using the Dirichlet tessellation of the set of points, for small values of p. This problem has applications to interpolation and contouring, for exam

We proposed a modified procedure of the direct inversion in the ## Ž . iterative subspace DIIS method to accelerate convergence in the integral equation theory of liquids. We update the DIIS basis vectors at each iterative step by using the approximate residual obtained in the DIIS extrapolation.
