Manage benders subproblems memory in the master scip instance (#1111) * Manage benders subproblems memory in the master scip instance * Update src/pyscipopt/scip.pxi Co-authored-by: João Dionísio <57299939+Joao-Dionisio@users.noreply.github.com> * Fix changelog --------- Co-authored-by: João Dionísio <57299939+Joao-Dionisio@users.noreply.github.com>
BUG: `_VarArray` can't handle `MatrixVar` (#1044) * Refactor _VarArray initialization and type checks Simplifies and clarifies the logic for initializing _VarArray by restructuring type checks and error handling. Now uses f-strings for error messages and ensures consistent handling of empty lists and invalid types. * Refactor _VarArray to support MatrixVariable input Updated the _VarArray class constructor to handle MatrixVariable inputs in addition to Variable, list, and tuple. Refactored pointer allocation logic into a helper function for improved code clarity and maintainability. * Add test for indicator constraint with matrix binary var Introduces a new test to verify that addConsIndicator works correctly when the binary variable is a matrix variable, addressing issue #1043. * Update CHANGELOG.md * Declare ptr variable in create_ptr function To fix "Storing unsafe C derivative of temporary Python reference" * Refactor create_ptr to remove redundant size argument The create_ptr function in _VarArray.__cinit__ no longer takes a separate size argument and instead uses len(vars) directly. This simplifies the function signature and reduces redundancy. * Refactor _VarArray initialization logic Inlined the pointer creation logic in _VarArray's __cinit__ method, removing the inner create_ptr function. This simplifies the code and improves readability while maintaining the same functionality. * Update CHANGELOG * Update test for addConsIndicator with activeone flag The test now checks addConsIndicator with both activeone=True and activeone=False, and updates the objective to use binvar.sum(). * ENH: flatten list * BUG: use `np.ravel` avoid to run out of vars range * test binvar with (1, 1, 1) matrix * test binvar with (2, 3) matrix * test binvar with (2, 1) list of lists * correct index * Add TypeError test for addConsIndicator with binvar * Only requiring a 1D array * TST: raise an error while get not 1D array * MAINT: Update error message * TST: update error type * Update CHANGELOG.md * Fix _VarArray initialization for empty input Ensures _VarArray initializes ptr and size to NULL and 0, respectively, before processing input. Prevents allocation and assignment errors when an empty or invalid input is provided. * Remove _VarArray changing from changelog * TST: update the comparing method Co-authored-by: DominikKamp <130753997+DominikKamp@users.noreply.github.com> --------- Co-authored-by: João Dionísio <57299939+Joao-Dionisio@users.noreply.github.com> Co-authored-by: DominikKamp <130753997+DominikKamp@users.noreply.github.com>
