A class to manage the history along iterations of a solver
print_order : list or str
The list of values to print along iterations
values : dict
A
dictcontaining the history. Key is the value name and values are the values taken along the iterations
last_values : dict
A
dictcontaining all the last history values
_minimum_col_width : int
Minimal size of a column when printing the history
_minimizer : None or numpy.ndarray
The minimizer of the objective.
Noneif not specified. This is useful to compute a distance to the optimum.
_minimum : None or float
The minimal (optimal) value of the objective.
Noneif not specified. This is useful to compute a distance to the optimum.
_print_style : list or str
The display style of all printed numbers
_history_func : dict
A dict given for all values the function to be applied before saving and displaying in history. This is useful for computing the sparsity, the rank, among other things, of the iterates along iterations of the solver
_n_iter : int
The current iteration number
_col_widths : list or int
A list containing the computed width of each column used for printing the history, based on the name length of the column
