Dakota

Optimization

Dakota stands for "Design and Analysis toolKit for Optimization and Terascale Applications" and it is a general purpose optimization toolbox mostly developed by Sandia National Laboratories.

Dakota is a general-purpose software toolkit for performing systems analysis and design on high performance computers. Dakota provides algorithms for design optimization, uncertainty quantification, parameter estimation, design of experiments, and sensitivity analysis, as well as a range of parallel computing and simulation interfacing services.

The Dakota toolkit provides a flexible, extensible interface between analysis codes and iterative systems analysis methods. Dakota contains algorithms for:

  1. Optimization with gradient and nongradient-based methods
  2. Uncertainty quantification with sampling, reliability, stochastic expansion, and epistemic methods
  3. Parameter estimation with nonlinear least squares methods and
  4. Sensitivity/variance analysis with design of experiments and parameter study methods.

These capabilities may be used on their own or as components within advanced strategies such as hybrid optimization, surrogate-based optimization, mixed integer nonlinear programming, or optimization under uncertainty.
