DRSOM: A Dimension-Reduced Second-Order Method for Convex and Nonconvex Optimization

docs-stable docs-dev

DRSOM.jl is a Julia implementation of the Dimension-Reduced Second-Order Method for unconstrained smooth optimization.

DRSOM.jl now includes a bunch of algorithms, including the variants of original DRSOM and the HSODM: Homogeneous Second-order Descent Method.

Known issues

DRSOM.jl is still under active development. Please add issues on GitHub.
