Sparse Nonlinear Optimization Wrapper (SNOW)

Build Status <!-- Stable Dev -->

The problems we typically solve in our group are nonconvex, nonlinear, constrained, gradient-based, often computationally expensive, and sometimes have sparse Jacobians. This package wraps derivative computation methods and optimization solvers that are well-suited to these types of problems.

Features: - Allows easy switching between SNOPT and IPOPT from a common interface passing through all solver options, preserving output in files, and allowing warm starts (for SNOPT). - Easy switching between various differentiation methods: ForwardDiff, ReverseDiff, Zygote, FiniteDiff (forward, central, complex step), and user-defined derivatives. - Derivative calculations are all non-allocating during optimization. - Outputs are also cached as applicable to avoid unnecessary function calls. - Methods are provided to help determine sparsity patterns, sparse Jacobians can be updated efficiently with SparseDiffTools (using graph coloring), and the sparsity structure is passed to the solvers.
