torch_numopt.line_search

Line-search algorithms for step-length determination.

This module provides various line-search strategies: backtracking, interpolation, and bisection. Each solver implements a specific method and can be combined with different stopping conditions (Armijo, Wolfe, Goldstein, etc.).

Functions

create_line_search_solver(method, condition)

Factory function to instantiate a line-search solver.
