EasyScipyOptimizeDriver
- class topfarm.easy_drivers.EasyScipyOptimizeDriver(optimizer='SLSQP', maxiter=200, tol=1e-08, disp=True, auto_scale=False, **kwargs)[source]
- __init__(optimizer='SLSQP', maxiter=200, tol=1e-08, disp=True, auto_scale=False, **kwargs)[source]
- Parameters
optimizer ({'COBYLA', 'SLSQP'}) – Gradients are only supported by SLSQP
maxiter (int) – Maximum number of iterations.
tol (float) – Tolerance for termination. For detailed control, use solver-specific options.
disp (bool) – Set to False to prevent printing of Scipy convergence messages
auto_scale (bool) – Set to true to set ref0 and ref1 to boundaries of the desig variables for the drivers which support it (SLSQP, ).

EasySimpleGADriver
- class topfarm.easy_drivers.EasySimpleGADriver(max_gen=100, pop_size=25, Pm=None, Pc=0.5, elitism=True, bits={}, debug_print=[], run_parallel=False, random_state=None)[source]

SimpleGA driver with optional arguments
- Parameters
max_gen (int) – Number of generations before termination.
pop_size (int) – Number of points in the GA.
pm (float) – Probability of mutation.
pc (float) – Probability of cross over.
elitism (bool, optional) – If True, replace worst performing point with best from previous generation each iteration.
bits (dict, optional) – Number of bits of resolution. Default is an empty dict, where every unspecified variable is assumed to be integer, and the number of bits is calculated automatically. If you have a continuous var, you should set a bits value as a key in this dictionary. Ex: {‘x’:16,’y’:16}
debug_print (list, optional) – List of what type of Driver variables to print at each iteration. Valid items in list are ‘desvars’,’ln_cons’,’nl_cons’,’objs’
run_parallel (bool) – Set to True to execute the points in a generation in parallel.
