jax.scipy.optimize.OptimizeResults#

class jax.scipy.optimize.OptimizeResults(x, success, status, fun, jac, hess_inv, nfev, njev, nit)[source]#

Object holding optimization results.

Parameters:

  • x (jax.Array) – final solution.

  • success (bool | jax.Array) – True if optimization succeeded.

  • status (int | jax.Array) – 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 (jax.Array) – final function value.

  • jac (jax.Array) – final jacobian array.

  • hess_inv (jax.Array | None) – final inverse Hessian estimate.

  • nfev (int | jax.Array) – integer number of function calls used.

  • njev (int | jax.Array) – integer number of gradient evaluations.

  • nit (int | jax.Array) – integer number of iterations of the optimization algorithm.
