Basc: Constrained Approximation by Semidefinite Programming

, 2016
This article details the theoretical grounds for a semidefinite-programming-based method that computes best approximants by splines under some general constraints and relative to several function norms, notably the max-norm.

Fast Spectral Projection Algorithms for Density-Matrix Computations

, 1998
We present a fast algorithm for the construction of a spectral projector. This algorithm allows us to compute the density matrix, as used in e.g the Kohn-Sham iteration, and so obtain the electron density.

A New Global Optimization Algorithm

, 1996
. We present a new global optimization method and one of its applications to an eigenvalue problem. We will prove the convergence of this algorithm. This algorithm is based on automatic differentiation and the higher order derivative method. It consists

HILBERT-SPACE TECHNIQUES FOR SPECTRAL REPRESENTATION IN TERMS OF OVERCOMPLETE BASES

, 2007
Topics associated with the representation of objects from a separable Hilbert space in terms of an a priori given overcomplete system (dictionary) of its generators (atoms) are handled. First the procedure of nding such a representation is formulated and

LEARNING TO PREDICT PHYSICAL PROPERTIES USING SUMS OF SEPARABLE FUNCTIONS∗

, 2011
. We present an algorithm for learning the function that maps a material structure to its value on some property, given the value of this function on several structures.

A new line search technique

, 2004
In this paper the problem of line search, an important step in most multidimensional optimization algorithms, is considered.If conjugate gradient descent is to be used in producing a descent sequence for a given functional f on a Hilbert space H, then at
