pyOptSparse
pyOptSparse is an object-oriented framework for formulating and solving nonlinear constrained optimization problems in an efficient, reusable, and portable manner. Some key features of pyOptSparse include:
Object-oriented development, which maintains independence between the optimization problem formulation and its solution by different optimizers
The use of sparse matrices throughout the code, to more efficiently handle large-scale optimization problems
Parallel model execution under MPI, both for expensive analyses that must be done in parallel, and for parallel function evaluation when using certain gradient-free optimizers
The optimization histories can be stored during the optimization process, and a partial history can also be used to hot-restart the optimization
A post-processing GUI utility called OptView to analyze optimization results
pyOptSparse is a fork of pyOpt. However, it is not backwards compatible with pyOpt and thus optimization scripts will need to be modified to use pyOptSparse.
