Interface AdjointBfgsOptions

Tolerance for ||c(p, x)|| = 0. Default: 1e-6

Analytical ∂c/∂p. Size constraintCount × parameterCount.

Analytical ∂c/∂x. Must be square (constraintCount === stateCount). Ill-conditioned Jacobians can be sensitive; raise regularization if needed.

Analytical ∂f/∂p. Used instead of finite differences when provided.

Analytical ∂f/∂x. Used instead of finite differences when provided.

Options passed to Strong Wolfe line search.

Log level for detailed logging output. Controls which log messages are displayed:

• DEBUG: Detailed progress information (cost, gradient norm, step size, etc.)
• INFO: Convergence messages and important state changes
• WARN: Warnings (singular matrix, max iterations reached, line search failure, etc.)
• ERROR: Fatal errors (currently not used, reserved for future extensions)

If verbose is true and logLevel is not specified, logLevel defaults to INFO. If both logLevel and verbose are specified, logLevel takes precedence. Default: undefined (no logging)

Maximum number of iterations before stopping. Default: 1000

Callback function called at each iteration for progress monitoring. Useful for debugging and monitoring convergence.

Base Tikhonov regularization for solves involving ∂c/∂x. Default: 0 (an automatic floor may still apply when the Jacobian is singular)

Fixed step size used only when useLineSearch is false. Default: 1.0

Finite-difference step for derivatives with respect to parameters. Default: 1e-6

Finite-difference step for derivatives with respect to states. Default: 1e-6

Tolerance for convergence check (gradient norm, step size, etc.). Default: 1e-6

Levenberg-Marquardt and constrained Levenberg-Marquardt prefer tolGradient / tolStep / tolResidual. If those are omitted, this value is used as a common fallback.

Whether to use Strong Wolfe line search. Default: true

Enable verbose logging for debugging. When true, detailed information is logged to console. Default: false
