jax.scipy.optimize.OptimizeResults

class jax.scipy.optimize.OptimizeResults(x: Array, success: bool | Array, status: int | Array, fun: Array, jac: Array, hess_inv: Array | None, nfev: int | Array, njev: int | Array, nit: int | Array)

Object holding optimization results.

Parameters:

• x – final solution.

• success – True if optimization succeeded.

• status – integer solver specific return code. 0 means converged (nominal), 1=max BFGS iters reached, 3=zoom failed, 4=saddle point reached, 5=max line search iters reached, -1=undefined

• fun – final function value.

• jac – final jacobian array.

• hess_inv – final inverse Hessian estimate.

• nfev – integer number of function calls used.

• njev – integer number of gradient evaluations.

• nit – integer number of iterations of the optimization algorithm.
