What does Pandrosion 455 do?
Pandrosion is a numerical solver for real and complex nonlinear systems, distributed as one standalone Python file with NumPy as its external dependency. If you need a root, check root_success; a stationary point alone is not enough.
What does the $49 USD price include?
Access to the frozen release 455 delivery: the Python file, documentation, tests, validation reports and Lean proof material. This is a one-time purchase with no subscription or promise of future releases. Network fees are additional.
Can an AI agent purchase and download the software?
Yes. The guide and API let an agent inspect the product, create a five-minute quote, submit a payment signed by an authorized wallet and download the files after verification and finality. No account, email or JavaScript is needed to use the API.
Which payment methods are accepted?
Payment is in cryptocurrency using the networks and assets currently available in the checkout and API. The amount equivalent to $49 USD is fixed in a five-minute quote. Use the order’s payment instructions; a plain transfer to an address is not sufficient.
Can I use the code commercially?
Yes, under the MIT license. Commercial use, modification and redistribution are permitted under its terms. Payment provides convenient access to this release’s bundle; it does not grant exclusive rights.
What are the limitations, and is a free version available?
Measurements depend on cases and platform: no universal convergence or speedup is guaranteed. Proofs cover mathematical models, not Python or NumPy end to end. Public release 449 remains free for an initial evaluation; it is a separate release from 455.
