This paper develops central limit theorems (CLT's) and large deviations results for additive functionals associated with reflecting disions in which the functional may include a term associated with t...
This paper analyzes the convergence properties of an iterative Monte Carlo procedure proposed in the Physics literature for estimating the quasi-stationary distribution on a transient set of a Markov ...
By dark of night they howl across Delaware Bay, these winds that reach 60 miles per hour. The gales of a nor'easter in May—a winter storm that happens this late in the season only once a century—overt...
In order to become effective teachers of language and literacy, it is critical for teacher candidates to have a sense of who they are as literate beings, how their literacy pasts have been lived, ...
Biodiesel production has increased dramatically over the last decade, raising the need for new rapid and non-destructive analytical tools and technologies. 1 H Low Field Nuclear Magnetic Resonance (...
QPOPT is a set of Fortran subroutines for minimizing a general quadratic function subject to linear constraints and simple upper and lower bounds. QPOPT may also be used for linear programming and f...
We discuss the solution of regularized linear programs using a primal-dual barrier method. Our implementation is based on indeˉnite Cholesky-type factorizations of full and reduced KKT systems. Regu...
SNOPT is a general-purpose system for constrained optimization. It minimizes a linear or nonlinear function subject to bounds on the variables and sparse linear or nonlinear constraints. It is suita...
Cholesky factorizations have reached a high peak of e±ciency for solving sparse symmetric systems, largely because their Analyze and Factor phases do not con°ict. We explore the possibility of using...
The time-frequency and time-scale communities have recently developed a large number of overcomplete waveform dictionaries—stationary wavelets, wavelet packets, cosine packets, chirplets, and warple...
The lasso penalizes a least squares regression by the sum of the absolute values (L1-norm) of the coefficients. The form of this penalty encourages sparse solutions (with many coefficien...
The new algorithm has been implemented in Matlab, with an option to use either MINOS or SNOPT (Fortran codes) to solve the linearly constrained subproblems. Only first derivatives are required...
Stable and efficient updates to the basis matrix factors are vital to the simplex method. The "best" updating method depends on the machine in use and how the update is implemented. For example, the ...
Methods are discussed for the solution of sparse linear equations Ky z, where K is symmetric and indefinite. Since exact solutions are not always required, direct and iterative methods are both of i...
Kalman [9] introduced a method for estimating the state of a discrete linear dynamic system subject to noise. His method is fast but has poor numerical properties. Duncan and Horn [3] showed that th...
