v0.2.0

Phydrax v0.2.0

Phydrax 0.2.0 is a major ergonomics and performance release across sampling, differentiation, PCI overlays, and examples.

Highlights

1) Unified sampling API (num_points)

Constraint sampling now uses a single interface:

• Dense: num_points=1024 or num_points=(256, 256)
• Coord-separable: num_points={"x": 128, "t": 256}
• Mixed dense + separable: num_points=(8, {"x": axis_spec})

This removes split configuration and simplifies sampling setup.

2) Differential operator execution upgrades

• Explicit AD engine behavior (including JVP path) where applicable

This improves consistency and helps optimized routes apply to structured/
factorized models.

Physics-Constrained Interpolation (PCI) enforced overlays now better
preserve optimized derivative paths through composition, including:

• Derivative-aware blend/quotient-style composition
• Improved boundary/initial compatibility handling
• Better propagation of optimized derivative behavior through enforced ansätze

4) New example: examples/wave1d.py (Marimo notebook)

Added a full tutorial wave equation example demonstrating:

• Latent-factorized modeling
• PCI-enforced BC/IC overlays

Public notebook:

• https://static.marimo.app/static/wave1d-ul81

5) Docs/site updates

• Added Docs → Examples → Overview

• Added LinkedIn docs branding/icon updates

• Updated guides/API docs for new sampling and differentiation behavior

• Version bump: 0.1.1 → 0.2.0

• Notebook deps surfaced for example workflow (marimo, matplotlib)

• Solver training logs include per-iteration timing

Migration notes

Sampling API

If you previously used separate coord-separable sampling arguments, migrate to num_points forms.

Before:

num_points=8
coord_separable={"x": phx.domain.UniformAxisSpec(nx)}
dense_structure=phx.domain.ProductStructure((("data",),))

After:

num_points=(8, {"x": phx.domain.UniformAxisSpec(nx)})
dense_structure=phx.domain.ProductStructure((("data",),))

Or fully separable:

num_points={"x": 128, "t": 256}

Validation scope

This release includes broad test updates/additions across:

• Constraint sampling behavior and edge cases
• Differential operators/runtime cache behavior
• Latent contraction structured/flat behavior
• Enforced solver/overlay behavior
• Docs example execution path
