SimpleRose Platform v3.0.0 (June 3, 2025)

Rose Solver (v4.14.5)

Solution Methods

• Added support for new heuristics along with validation steps to ensure heuristic solutions are valid
• Rose now supports cuOpt version 25, expanding compatibility with external GPU-based solvers.

Architectural Improvements

• Introduced a constraint model to track MIP-specific information for smarter heuristic and method selection
• Added support for reduced cost strengthening
• Introduced domain propagation capabilities
• Added a solution pool and prime space access for future expansion

Interface and Integration

• Incorporates with new contract standards between other applications
• Output metrics are now organized by topic and include distributed run information
• Improved internal file support, including new outputs to assist in integration with downstream tools

Performance Optimizations

• Optimized node storage, sorting, queueing, and management in distributed solve environments
• Improved LP solve data structures for faster and more memory-efficient performance
• Streamlined distribution communication, reducing latency and overhead

Robustness Enhancements

• Fixed issues in reporting and termination logic, improving reliability

Web Interface (v0.7.0)

Distributed Solves Support

• Users can now submit distributed solves via the user interface and view the selected configuration clearly on the solutions page
• The interface dynamically fetches and displays allowed node counts based on organizational settings, ensuring that users only see valid options

Dashboard Filter & Sort Persistence

• Filter, sort, and page selections are now stored in session storage and synchronized with the URL, allowing users to retain state across navigation
• Supports bookmarking and sharing filtered solve views

Usability Improvements

• Improved the cancel confirmation message, now including the problem name for clearer context
• Enhanced handling and display of 500 errors, with more consistent and informative messages across the app
• Updated status chips with revised colors and improved icons for optimal, error, and other states to enhance readability and visual feedback.

Rose Solver Integration

• Updated the interface to support and render new Rose 4–specific metrics

Backend Components (v0.7.0)

Distributed Solves Support

• Introduced support for distributed solve workflows, including infrastructure, solve limits, job failure handling, and various hardware compatibility.

Enhanced Observability & Tracing

• Integrated new solve tracing across solve workflows, including solve submission and cancellation
• Enabled service graphs and standardized observability backends
• Improved tracing labels and user-friendly naming to help with debugging and performance analysis

User Account & Organization Management

• Added user filtering support to the backend for future use in the user interface
• Introduced a new organization configuration endpoint to centralize and manage org-specific settings.

Error Handling & Stability Improvements

• Generalized user-facing error messages for clarity
• Added alarms for zombie solves and job failures
• Improved handling of signal terminate messages and added support for requeue delays and retry policies in distributed solve jobs

Validation and Security Enhancements

• Added validation for uploaded filenames
• Prevented deletion of critical infrastructure components
• Updated IAM policies to support secure backups

Rose Solver Integration

• Integrated Rose v4.14.5 with improved default versioning for distributed environments
