concept SeederStrategy =
    std::default_initializable<S> &&
    requires(S &seeder, const NDArray<T, 2> &X, std::size_t k, std::uint64_t seed, math::Pool pool,

    }

Detailed Description

Contract for the seeder that produces initial centroids for the Lloyd driver.

The seeder owns its private scratch and writes the k initial centroid rows directly into the caller-provided centroid matrix. No auxiliary output buffers cross the seeder boundary; the Lloyd driver owns its own per-point distance scratch.

Template Parameters

S	Candidate seeder policy type.
T	Element type of the point cloud.
