DESDEO 2.2.0

Core logic

Added

• Added a seeded population generator for evolutionary multiobjective optimization:
  • Supports generating populations by perturbing a provided seed solution.
  • Allows controlling the ratio of seeded vs. random solutions.
  • Supports all variable types.

Fixed

• Fixed issues in the seeded generator implementation discovered during integration and testing.

---

Web API

Changed

• Refactored session context handling:
  • get_session_context is now used consistently in the endpoints.
  • Removed redundant checks around interactive state retrieval; invalid states now raise immediately.
• Applied linter-driven cleanup (removal of deprecated imports, improved import ordering, minor syntax fixes).
• Access tokens are now returned as cookies as well (previously this was a feature just for refresh tokens).

---

Web GUI

Added

• Added a problem definition page (WIP), including:
  • Initial problem definition form.
  • Iterative refinements to structure and validation.
• Added initial support for selecting interactive sessions in the method-selection view, analogous to problem selection.

Changed

• Improved E-NAUTILUS session startup and validation logic.
• Updated session and startup inputs for E-NAUTILUS.
• Fixed missing session information in the E-NAUTILUS selection state.
• Refined session settings UI for E-NAUTILUS.
• Improved authentication flow by refreshing access tokens on 401 responses and updating cookies accordingly.

Known issues

• Deleting sessions can currently break NIMBUS if it attempts to access states from a deleted session.

---

Tests

Changed

• Improved Makefile test rules:
  • Better handling of skipped tests.
  • Added a dedicated make test-api rule.
  • General cleanup and variable handling improvements.
• Fixed test setup issues on the home page.

---

Tooling, CI, and linting

Changed

• Applied extensive ruff-based linting fixes across the codebase.
• Cleaned up code to satisfy pre-commit hooks.
• Minor workflow and maintenance-related refinements.

---

Documentation

Changed

• Updated README.md:
  • Clarified the development status of the Web GUI.
  • Updated installation instructions.
  • Revised funding information.
  • Reordered and expanded project badges, including PyPI version badge.
• Minor documentation fixes and clarifications.

---

Notes

• Several components (notably the Web GUI and session management) remain actively evolving research prototypes.

Rumo has it...

• Codex/fix token refresh logic in webui by @gialmisi in #416
• Core-logic (EMO): implemented a seeded generator by @gialmisi in #413
