"    Input:  {
                (sample_size)       - number of "shots" to use in each quantum program execution
                (max_iterations)    - a (soft) limit on the number of optimizer's iterations
                (start_param_value) - set the starting value for each optimizer's parameter (a float number or the word 'random')
                (repetitions)       - a number of times to run the whole optimizer convergence experiment (for stats)
                (provider)          - 'ibm' or 'rigetti' (see default_provider)
                (device)            - which simulator or quantum device to run the whole experiment on (interactive by default)
                (timestamp)         - when the experiment was started (normally generated automatically)
                (timeout)           - timeout for the device
