OPTIMIZED STANDALONE
One Python file. The evidence alongside it.
Release 455 solves real and complex nonlinear systems with NumPy as its external dependency. The complete delivery includes the standalone file, usage documentation, tests, numerical validation reports and scoped Lean proof material.
A normal evaluation budget of 6,000 keeps the default bounded. The reinforced profile is an explicit choice for harder cases.
MEASURED, WITH A STATED SCOPE
Less overhead than 454.
Paired measurements report a median 1.32% reduction in total runtime on 1,095 representative cases (five repetitions) and 13.24% on 19 difficult cases (three repetitions). The bundle includes the protocols and results.
These measurements depend on the cases and platform. They do not guarantee a speedup or convergence for every system.

Your payment request
Save your private access receipt below, then continue to Stripe. Return here after payment to download your files.

Order:
Keep this receipt to restore your downloads on another device. It contains a secret access key: do not share it or put it in a transaction memo.
Use this payment request. A plain transfer to the address alone does not contain the order reference and cannot unlock your download automatically.
Payment instructions for an agent or another wallet
Your downloads are ready.
Use root_success when you need a root. The bundle documents the default evaluation budget, reinforced profile and limits of the proofs.
For a late or insufficient payment, contact b.ivan.fr@gmail.com with your order ID and transaction hash. Do not send a second payment until the first is resolved. Never send your private key or seed phrase.

What your purchase includes
- Standalone Python solver · release 455115,586 bytes, identified by its SHA-256 hash
- Complete standalone and validation bundleZIP · 28,959,488 bytes · documentation, tests, reports and proof material
- MIT license and usage readmeCommercial use, modification and redistribution are permitted under the license.
This is a single purchase of the frozen 455 delivery, with no subscription or promise of future releases. MIT permits redistribution; the purchase provides convenient direct access to this package.
On 57,595 standard and reserved cases, the reported validation records 57,550 successes and 45 remaining failures, with no lost successes relative to 454 in that comparison. Check root_success when a root is required. The mathematical proofs do not verify Python or NumPy from end to end.
For AI agents and automated workflows
Read the agent purchase guide, OpenAPI specification and product manifest with file hashes. The API creates a five-minute quote, verifies the payment at blockchain finality and returns authenticated download links. No browser or email account is required. Agents can use direct invoices on the supported networks or x402 v2 with USDC on Base. The typed OpenAPI specification and reference Python client describe purchase, recovery and verified downloads. Save the private order receipt before paying.
The accepted list contains reviewed liquid assets on Solana and 24 EVM mainnets, including Ethereum, Base, Arbitrum One, Optimism, Polygon, BNB Smart Chain and Avalanche. See the complete network list and verification availability. Availability depends on a fresh price and working blockchain verification. Your wallet pays the exact quote plus network fees; a manual transfer without the order reference cannot be matched automatically.
Payment and access
Save the private access receipt before paying. It lets you restore your downloads on another device. Blockchain confirmation may finish after the five-minute quote expires, provided the transfer was included in time. Confirmation depends on the network and can take minutes or hours. The site waits for the network’s finalized block; it does not treat every EVM network as having Ethereum’s security. Funds and fees remain on the network you choose.
For a late, insufficient or unresolved payment, contact b.ivan.fr@gmail.com with your order ID and transaction ID before sending anything else. The website never requests a seed phrase or wallet private key. Read the MIT license and privacy information.
