Summary
This PR migrates legacy NumPy random API usage in
schelling.mdas part of QuantEcon/meta#299.The changes are confined to the exercise solution block. The main lecture flow uses Python's standard
randommodule (not NumPy), so it is out of scope for this migration.Details
from numpy.random import uniform, randintrng = np.random.default_rng()in the solution block, making the block self-containeduniform(size=(n, 2))→rng.uniform(size=(n, 2))randint(0, high=2, size=n)→rng.integers(0, 2, size=n)uniform(), uniform()→rng.uniform(), rng.uniform()randint(0, n)→rng.integers(0, n)U = uniform()→U = rng.uniform()No fixed seed was introduced. No Numba-related code is present.
Hi @mmcky and @HumphreyYang, I'd be grateful if you could take a look when you have time.
