tidy3d.plugins.design.MethodRandomCustom

class MethodRandomCustom

Bases: AbstractMethodRandom

Select parameters with an object with a user supplied sampler with a .random method.

Parameters:

• name (Optional[str] = None) – Optional name for the sweep method.

• num_points (PositiveInt) – Maximum number of sampling points to perform in the sweep.

• sampler (Optional[Any] = None) – An object with a .random(n) method, which returns a np.ndarray of shape (n, d) where d is the number of dimensions of the design space. Values must lie between [0, 1] and will be re-scaled depending on the design parameters. Compatible objects include instances of scipy.stats.qmc.QMCEngine, but other objects can also be supplied.

Example

>>> import tidy3d.plugins.design as tdd
>>> import scipy.stats.qmc as qmc
>>> sampler = qmc.Halton(d=3)
>>> method = tdd.MethodRandomCustom(num_points=20, sampler=sampler)
