Past software development projects:

    • Summary: LSALIB is a C++ library for efficient processing of text, computation of latent semantic analysis (LSA) models, computation of boolean and LSA queries, and computation of term-term or document-document similarities.
    • Contributions: Lead developer
    • Info: Latest version is 0.2.2
    • Availability: TBD

    • Summary: The DAKOTA (Design Analysis Kit for Optimization and Terascale Applications) toolkit provides a flexible, extensible interface between analysis codes and iterative systems analysis methods. DAKOTA contains algorithms for optimization with gradient and nongradient-based methods; uncertainty quantification with sampling, reliability, and stochastic finite element methods; parameter estimation with nonlinear least squares methods; and sensitivity/variance analysis with design of experiments and parameter study capabilities. These capabilities may be used on their own or as components within advanced strategies such as surrogate-based optimization, mixed integer nonlinear programming, or optimization under uncertainty.
    • Contributions: surrogate-based optimization, constraint relaxation for infeasible starting points, AMPL interface, DAKOTA-Coliny integration and testing
    • Info: Version 4.0 released May 12, 2006
    • License: GPL

  • Trilinos
    • Summary: The Trilinos Project is an effort to develop parallel solver algorithms and libraries within an object-oriented software framework for the solution of large-scale, complex multi-physics engineering and scientific applications. A unique design feature of Trilinos is its focus on packages.
    • Contributions: preconditioners for space-time (XYZT) iterative solution of transient PDEs
    • Info: Version 10.2 released 2010
    • License: LGPL
