The lmfit Python package provides a simple, flexible interface to non-linear optimization or curve fitting problems. The package extends the optimization capabilities of scipy.optimize by replacing floating pointing values for the variables to be optimized with Parameter objects. These Parameters can be fixed or varied, have upper and/or lower bounds placed on its value, or written as an algebraic expression of other Parameters.

The principal advantage of using Parameters instead of simple variables is that the objective function does not have to be rewritten to reflect every change of what is varied in the fit, or what relationships or constraints are placed on the Parameters. This means a scientific programmer can write a general model that encapsulates the phenomenon to be optimized, and then allow user of that model to change what is varied and fixed, what range of values is acceptable for Parameters, and what constraints are placed on the model. The ease with which the model can be changed also allows one to easily test the significance of certain Parameters in a fitting model.

The lmfit package allows a choice of several optimization methods available from scipy.optimize. The default, and by far best tested optimization method used is the Levenberg-Marquardt algorithm from MINPACK-1 as implemented in scipy.optimize.leastsq. This method is by far the most tested and best support method in lmfit, and much of this document assumes this algorithm is used unless explicitly stated. An important point for many scientific analysis is that this is only method that automatically estimates uncertainties and correlations between fitted variables from the covariance matrix calculated during the fit.

A few other optimization routines are also supported, including Nelder-Mead simplex downhill, Powell's method, COBYLA, Sequential Least Squares methods as implemented in scipy.optimize.fmin, and several others from scipy.optimize. In their native form, some of these methods setting allow upper or lower bounds on parameter variables, or adding constraints on fitted variables. By using Parameter objects, lmfit allows bounds and constraints for all of these methods, and makes it easy to swap between methods without hanging the objective function or set of Parameters.

Finally, because the approach derived from MINPACK-1 usin the covariance matrix to determine uncertainties is sometimes questioned (and sometimes rightly so), lmfit supports methods to do a brute force search of the confidence intervals and correlations for sets of parameters.

This is the Python 3 version of the package.

This is a simple C package for adaptive multidimensional integration (cubature) of vector-valued integrands over hypercubes. Of course, it can handle scalar integrands as the special case where f is a one-dimensional vector: the dimensionalities of f and x are independent. The integrand can be evaluated for an array of points at once to enable easy parallelization.

This package contains the development files.

LBFGS++ is a header-only C++ library that implements the Limited-memory BFGS algorithm (L-BFGS) for unconstrained minimization problems, and a modified version of the L-BFGS-B algorithm for box-constrained ones.

Psurface is a C++ library that handles piecewise linear bijections between triangulated surfaces. These surfaces can be of arbitrary shape and need not even be manifolds.

There are two main uses for psurface. When doing adaptive finite element simulations on grids with parametrized boundaries, psurface can store the parametrization. Boundary parametrizations are practically mappings from the coarse grid boundary to the actual boundary, and if that actual boundary is a triangulated surface then psurface can handle it. This is implemented, for example, in the dune-grid module of Dune.

Secondly, when doing domain decomposition methods with nonconforming interfaces, you need to relate the two interface grids to each other. Psurface can do this for you, even if your interfaces do not match geometrically. Such is the case, e.g., in contact problems. This second functionality is also available for 1d surfaces in 2d space.

The easiest way to use psurface for domain decomposition is to get the dune-grid-glue module and use it to drive psurface.

libquantum is a C library for the simulation of a quantum computer. Based on the principles of quantum mechanics, it provides an implementation of a quantum register. Basic operations for register manipulation such as the Hadamard gate or the Controlled-NOT gate are available through an easy-to-use interface. Measurements can be performed on either single qubits or the whole quantum register.

Features:

• Simulation of arbitrary quantum algorithms is possible
• High performance and low memory consumption
• Decoherence support for realistic quantum computation
• Interface for quantum error correction (QEC)
• Supports the density operator formalism
• Implementations of Shor's factoring algorithm and Grover's search algorithm are included

This package contains the header files and static libraries which are needed to develop applications based on libquantum.

The STochastic OPTimization library (StOpt) aims at providing tools in C++ for solving some stochastic optimization problems encountered in finance or in the industry. Different methods are available:

• dynamic programming methods based on Monte Carlo with regressions (global, local, kernel and sparse regressors), for underlying states following some uncontrolled Stochastic Differential Equations;
• dynamic programming with a representation of uncertainties with a tree: transition problems are here solved by some discretizations of the commands, resolution of LP with cut representation of the Bellman values;
• Semi-Lagrangian methods for Hamilton Jacobi Bellman general equations for underlying states following some controlled Stochastic Differential Equations;
• Stochastic Dual Dynamic Programming methods to deal with stochastic stock management problems in high dimension. Uncertainties can be given by Monte Carlo and can be represented by a state with a finite number of values (tree);
• Some branching nesting methods to solve very high dimensional non linear PDEs and some appearing in HJB problems. Besides some methods are provided to solve by Monte Carlo some problems where the underlying stochastic state is controlled. For each method, a framework is provided to optimize the problem and then simulate it out of the sample using the optimal commands previously computed. Parallelization methods based on OpenMP and MPI are provided in this framework permitting to solve high dimensional problems on clusters. The library should be flexible enough to be used at different levels depending on the user's willingness.

This package contains the headers and the static libraries (libstopt-mpi which allows for multithreading, and libstopt which does not).
