Keyboard Access
Navigation, links, skip links, and checkout entry points are intended to remain reachable without a mouse.
Website accessibility
Accessibility
The GPOPS-II website is being built to be usable by visitors with a wide range of abilities, devices, and assistive technologies.
Accessibility Features
The static website uses semantic HTML, readable contrast, keyboard-visible focus states, responsive layout, and descriptive page structure.
Screen Reader Structure
Pages use headings, landmarks, labels, and table headers so assistive technologies can expose the content clearly.
Readable Design
Text spacing, color contrast, responsive wrapping, and reduced-motion preferences are considered throughout the site.
Known limitations
Third-party checkout content may have separate accessibility behavior.
Some pricing-page controls are embedded from an external checkout service. The surrounding GPOPS-II page will provide accessible labels and page structure where possible, but the embedded checkout interface may be governed by the provider's own markup and scripts.
Need Help?
If you have difficulty accessing pricing, license, support, or example content, contact RP Optimization Research LLC and describe the page, browser, device, and assistive technology being used.
Ongoing Work
Accessibility will be reviewed as GPOPS-II examples, mathematical descriptions, documentation links, and purchase controls are added or updated.
Feedback welcome: Please report any accessibility barrier so it can be corrected in a future version of the website.
