OptimizationStats

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.
