Control parameters for DKGE joint diagonalisation

Usage

dkge_jd_control(
  maxit = 200L,
  step = 0.5,
  step_decay = 0.5,
  step_min = 1e-06,
  tol = 1e-07,
  linesearch = TRUE,
  armijo = 1e-04,
  verbose = FALSE,
  record = FALSE
)

Arguments

maxit: Maximum number of optimization iterations.
step: Initial step size for the projected gradient descent.
step_decay: Multiplicative decay applied during backtracking.
step_min: Minimum step size allowed before terminating.
tol: Convergence tolerance applied to both gradient norm and off-diagonal energy.
linesearch: Logical; when `TRUE` perform Armijo backtracking.
armijo: Armijo condition constant used during backtracking.
verbose: Logical; emit per-iteration progress when `TRUE`.
record: Logical; store per-iteration diagnostics.

Value

A list of control parameters.
