struct OptimizationStats

Stores the optimization run’s statistics that is returned in the stats field of the OptimizationResult.

Fields

  • iterations: number of iterations

  • time: time taken to run the solver

  • fevals: number of function evaluations

  • gevals: number of gradient evaluations

  • hevals: number of hessian evaluations

Default values for all the field are set to 0 and hence even when you might expect non-zero values due to unavilability of the information from the solver it would be 0.
