scipy.optimize._trustregion_exact:IterativeSubproblem
source: build-install/usr/lib/python3.14/site-packages/scipy/optimize/_trustregion_exact.py:190
Signature
class IterativeSubproblem(x, fun, jac, hess, hessp = None, k_easy = 0.1, k_hard = 0.2, maxiter = None)Members
Summary
Quadratic subproblem solved by nearly exact iterative method.
Notes
This subproblem solver was based on [1], [2] and [3], which implement similar algorithms. The algorithm is basically that of [1] but ideas from [2] and [3] were also used.
