The goldstein conditions
WebShow that the one-dimensional minimizer of a strongly convex quadratic function always satisfies the Goldstein conditions This problem has been solved! You'll get a detailed … WebGoldstein or Wolfe conditions can be imposed on a linesearch to ensure convergence of an iterative nonlinear optimization algorithm to a stationary point. However it is actually not necessary to find a single step which satisfies both Goldstein (or both Wolfe) conditions simultaneously in order to ensure global convergence.
