- examples/animate_propagation_of_chaos.py: 4-panel McKean-Vlasov
simulator at N in {20, 100, 500, 4000} with reference N=12000;
bottom panel tracks W_2(mu^N_t, mu_t) on log scale -> visible
1/sqrt(N) decay (Sznitman 1991).
- examples/propagation_of_chaos.gif (1.6 MB)
- README: new 'Propagation of chaos' subsection under
Mean-field & agent-based dynamics, with empirical-measure
formula, k-tuple factorisation and GIF embed.
- examples/notebooks/14_mckean_vlasov.ipynb: sandwich PRE/code/POST
cells demonstrating W2 ~ 1/sqrt(N) on the same simulator.
Verified executed: sqrt(N)*W2 ~ 0.7 across N (theoretical const).
- Restore correct PyPI distribution name 'optimiz-rs' (continuity with v1.0.x).
Rust crate stays 'optimiz-rs'; Python module is 'optimizr'.
- python/optimizr/__init__.py:
* Bump __version__ from stale '0.2.0' to '2.0.0'.
* Eagerly bind every v2 primitive from _core (so dir(optimizr), IDE
auto-complete and 'from optimizr import X' all work without relying on
the lazy __getattr__ fallback).
* Extend __all__ with 38 new v2 entries.
- README.md: full v2 features section grouped by domain (rough volatility,
BSDE/PDE, stochastic control, mean-field, topology/graphs/signatures,
risk/robust inference, point processes, Kalman). Embedded
examples/mckean_vlasov.gif at the top. Added v2 benchmark table.
- examples/benchmark_v2.py: honest benchmark vs pure-Python/NumPy
references on intrinsically loopy workloads. Best-of-3, single-thread,
Apple M2: HMM 67.7x, DE 13.9x, signatures 11.2x, Hawkes 3.3x, MCMC 1.7x.
- examples/animate_mckean_vlasov.py + examples/mckean_vlasov.gif (5MB):
cinematic 800-particle mean-reverting McKean-Vlasov flow animation
using optimizr.mean_reverting_mckean_vlasov.
- tests/test_v2_api.py already in place: 20/20 pass.
- Bump Cargo.toml + pyproject.toml from 2.0.0-alpha.1 to 2.0.0.
- Restore PyPI distribution name to 'optimizr' (continuity with v1.4.x).
Rust crate stays 'optimiz-rs'; both expose Python module 'optimizr'.
- README: new 'What's New in v2.0.0' section listing every advertised
primitive (solve_volterra, solve_fractional_ode, linear_bsde_constant_coeffs,
mean_reverting_mckean_vlasov, historical_var_py, etc.) with corrected
install command 'pip install optimizr'.
- tests/test_v2_api.py: 20-test non-regression suite with analytic
ground-truth checks for every v2 primitive plus a parametrised guard
over the v1.x public surface.
- CHANGELOG: 2.0.0 entry documenting the release.
Build verification:
- maturin develop --release --features python-bindings -> optimizr-2.0.0 wheel built
- pytest tests/test_v2_api.py: 20 passed, 0 failed
- cargo test --lib --no-default-features: 124 passed; 5 pre-existing failures
(mrsjd, ou_estimator, hurst_random_walk, hjb_solver_symmetry, regime_switching)
unchanged since v1.1.
