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.
  • Started work on a resolver–provider–schema–based mechanism for connecting to external test problem libraries without relying on HTTP (initial support for Pymoo-based problems).
  • 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).
  • Added endpoints for retrieving all iterations, votes, confirmations, and intermediate solutions in group decision-making workflows.
  • Added support for defining optimization problems via JSON file uploads.
  • Added new example problems to database initialization scripts.

Changed

  • Refactored database session handling to propagate active sessions explicitly instead of relying on implicit generators.
  • 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

  • Several endpoints and request/response models should be considered unstable and subject to change as research workflows mature.

Web GUI

Added

  • Added initial GNIMBUS UI (WIP), including:
    • Group and method selection views.
    • Voting-based decision and compromise phases.
    • End-state views with objective and variable tables and CSV export.
  • Added iteration history views with the ability to revert to previous iterations (WIP).
  • Added real-time updates via WebSockets for phase changes, iteration updates, and voting results.
  • Added new visualizations, including vote bar charts and extended parallel coordinate plot features.

Changed

  • Migrated OpenAPI client generation to Orval 8.x and regenerated client models.
  • Refactored preference sidebars, solution tables, and layout components for clarity and experimentation.
  • Continued work on authentication and session handling in the GUI (cookies + token-based access).
  • Iteratively refined dashboards, top bars, and phase-specific views.

Fixed

  • Fixed WebSocket reconnection and shutdown handling.
  • Fixed phase update propagation, layout resizing issues, tooltip rendering, and visualization inconsistencies.
  • Fixed UI behavior during compromise and voting phases (e.g., disabled invalid actions, improved feedback).

Notes

  • Large parts of the GUI remain research prototypes; UI structure, naming, and interaction patterns may change rapidly.

Rumor has it...
