📉 #PINNverse crushes parameter error — even with:
- High noise
- Terrible initial guesses

Stable & accurate where others fail (e.g., Fisher-KPP).

💥 Why is this a breakthrough?

Standard PINNs miss non-convex Pareto fronts → overfit.
#PINNverse captures the entire Pareto front → balances physics + data perfectly.

🔑 The big idea:

Classical PINNs use weighted-sum loss → often fails.
#PINNverse reframes it as constrained optimization → unlocks better solutions.

Small change, huge impact!

📊 How does #PINNverse stack up?

✅ beats Nelder-Mead & classical PINNs
✅ handles noisy data & bad initial guesses
✅ tested on 4 tough benchmarks:
- Kinetic reaction ODE
- FitzHugh–Nagumo
- Fisher–KPP PDE
- Burgers’ PDE

🚀 Introducing #PINNverse — a game-changer for parameter estimation in differential equations! 🧠💡

No forward solves. Better accuracy. Robust to noise.
