PyBOP - v25.3

Full Changelog: https://github.com/pybop-team/PyBOP/blob/develop/CHANGELOG.md

v25.3 - 2025-03-28

Features

  • #649 - Adds verbose outputs to Pints-based optimisers
  • #659 - Enables user-defined weightings of the error measures.
  • #674 - Adds the reason for stopping to the OptimisationResult.
  • #663 - Adds DFN fitting examples alongside synthetic data generation methods.

Optimisations

  • #676 - Update the format of the problem sensitivities to a dict.
  • #681 - Update the spatial variable defaults of the GroupedSPMe model.
  • #692 - Improvements/fixes for BaseSampler and BasePintsSampler classes, adds ChainProcessor classes w/ clearer structure.

Bug Fixes

  • #678 - Fixed bug where model wasn't plotted for observer classes with pybop.plot.quick().

Breaking Changes

  • #684 - Updates plot.quick to plot.problem for clarity.
  • #661 - Adds pybop.CostInterface which aligns the optimisers and samplers with a unified call_cost in which transformations and sign inversions are applied. Also includes bug fixes for transformations and gradient calculations.

PyBOP - v25.1

Full Changelog: https://github.com/pybop-team/PyBOP/blob/develop/CHANGELOG.md

v25.1 - 2025-02-03

Features

  • #636 - Adds pybop.IRPropPlus optimiser with corresponding tests.
  • #635 - Adds support for multi-proposal evaluation of list-like objects to BaseCost classes.
  • #635 - Adds global parameter sensitivity analysis with method BaseCost.sensitivity_analysis. This is computation is added to OptimisationResult if optimiser arg compute_sensitivities is True. An additional arg is added to select the number of samples for analysis: n_sensitivity_samples.
  • [#630] (https://github.com/pybop-team/PyBOP/pull/632) - Fisher Information Matrix added to BaseLikelihood class.
  • #619 - Adds pybop.SimulatingAnnealing optimiser with corresponding tests.
  • #565 - DigiBatt added as funding partner.

Optimisations

  • #638 - Allows the problem class to accept any domain name.
  • #618 - Adds Mean Absolute Error (MAE) and Mean Squared Error (MSE) costs.
  • #601 - Deprecates MultiOptimisationResult by merging with OptimisationResult.
  • #600 - Removes repetitious functionality within the cost classes.

Bug Fixes

  • #602 - Aligns the standard quick plot of MultiFittingProblem outputs.

Breaking Changes

  • #656 - Completes ParameterSet changes from #593 and aligns the simulation options in model.predict with the model properties such as the solver.
  • #593 - Enables ParameterSet to systematically return a pybamm.ParameterValues object within the model class.
