Release notes

Sourced from pyscipopt's releases.

v6.1.0 - Bugfixing, matrix and expression performance, better stubs

This was a very active month. Thank you to @​Zeroto521 for all your work on improving PySCIPOpt's performance, and thank you, @​jonathanberthias, for the introduction and continued support of type stubs. Thank you to all the others who helped during this time, either with PRs or by reporting bugs. Several of the repo's oldest issues have been addressed (for the curious, #1150, #993, #1161, #1151, #1132). PySCIPOpt is entering a new phase, with more people contributing and becoming active participants in the repo. Makes me very happy; it's a sign of a vibrant community. This does increase the maintenance effort, so if you would like to help in that regard, please contact me by email ([email protected]).

Changelog

Sourced from pyscipopt's changelog.

6.1.0 - 2026.01.31

Added

  • Support for SCIP 10.0.1
  • Added automated script for generating type stubs
  • Include parameter names in type stubs
  • Added pre-commit hook for automatic stub regeneration (see .pre-commit-config.yaml)
  • Wrapped isObjIntegral() and test
  • Added structured_optimization_trace recipe for structured optimization progress tracking
  • Added methods: getPrimalDualIntegral()
  • getSolVal() supports MatrixExpr now

Fixed

  • getBestSol() now returns None for infeasible problems instead of a Solution with NULL pointer
  • all fundamental callbacks now raise an error if not implemented
  • Fixed the type of MatrixExpr.sum(axis=...) result from MatrixVariable to MatrixExpr.
  • Updated IIS result in PyiisfinderExec()
  • Model.getVal now supports GenExpr type
  • Fixed lotsizing_lazy example
  • Fixed incorrect getVal() result when _bestSol.sol was outdated
  • Fixed segmentation fault when using Variable or Constraint objects after freeTransform() or Model destruction
  • getTermsQuadratic() now correctly returns all linear terms

Changed

  • changed default value of enablepricing flag to True
  • Speed up MatrixExpr.sum(axis=...) via quicksum
  • Speed up MatrixExpr.add.reduce via quicksum
  • Speed up np.ndarray(..., dtype=np.float64) @ MatrixExpr
  • Speed up Expr * Expr via C-level API and Term * Term
  • Speed up Term * Term via a $O(n)$ sort algorithm instead of Python $O(n\log(n))$ sorted function. Term.__mul__ requires that Term.vartuple is sorted.
  • Rename from Term.__add__ to Term.__mul__, due to this method only working with Expr * Expr.
  • MatrixExpr and MatrixExprCons use __array_ufunc__ protocol to control all numpy.ufunc inputs and outputs
  • Set __array_priority__ for MatrixExpr and MatrixExprCons
  • changed addConsNode() and addConsLocal() to mirror addCons() and accept ExprCons instead of Constraint
  • Improved chgReoptObjective() performance
  • Return itself for abs to UnaryExpr(Operator.fabs)
