Web API

Added

  • Added E-NAUTILUS finalize state and endpoint.
  • Added ENautilusTreeNodeResponse, ENautilusDecisionEventResponse, and ENautilusSessionTreeResponse models.

  • 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.

DESDEO 2.1.0

General

Core logic

Added

  • Added Group NIMBUS (GNIMBUS) method to the core optimization framework.
  • Added new ADM variants (ADM2, ADMAfsar) and refactored the ADM codebase with clearer base abstractions.

  • Added preliminary infrastructure for improved solver metadata handling.

Changed

  • Reworked the computation of intermediate solutions (WIP) to improve numerical robustness and alignment with theoretical formulations.
  • Refactored solver and reference vector handling as part of ongoing structural cleanup.

Fixed

  • Fixed division-by-zero issues in the GUESS scalarization (implementation previously deviated from the paper).
  • Fixed circular imports, mismatched parentheses, and multiple small numerical and structural issues discovered during refactoring.

Notes

  • Several core-logic changes in this release are experimental and may evolve as methodological work continues.

Web API

Added

  • Added new endpoints and request models for stepping, reverting, and inspecting E-NAUTILUS iterations (WIP).

  • Improved authentication handling: access and refresh tokens are now supported via cookies and explicit Authorization headers.
  • Continued work on multi-valued constraint handling and intermediate-result computation.

Fixed

  • Fixed multiple issues in Group NIMBUS–related endpoints, including incorrect group ID usage and broken tests.
  • Fixed API inconsistencies in get_or_initialize, utopia, and intermediate-solution endpoints.

Notes

Fixed

  • Fixed WebSocket reconnection and shutdown handling.
  • Fixed phase update propagation, layout resizing issues, tooltip rendering, and visualization inconsistencies.
