On Analysis → Extra, expand Minimizer. Choose the descent strategy, then set the maximum iterations and chi-square tolerance. These settings control the crysta minimizer.

  • Ladder
  • Fast descent
  • Fast descent with linear snap
  • Fast descent with guarded linear snap
  • Multi-start with pruning

Keep the default strategy for a first fit. Before changing search settings, check the starting model, free parameters and residual. See minimization and uncertainty for the objective and interpretation of results.

Choose the descent strategy and convergence settings.
