------------------------------------------------------------------- Tue Aug 8 11:36:35 UTC 2023 - Stefan Brüns <stefan.bruens@rwth-aachen.de> - Fix build with re2 2023-07-01, add 0001-deps-bump-re2-to-2023-07-01.patch - Cleanup skipped tests ------------------------------------------------------------------- Sun Jul 9 21:21:56 UTC 2023 - Stefan Brüns <stefan.bruens@rwth-aachen.de> - Fix build with latest protobuf, add 0001-base-Remove-AbslStringify.patch ------------------------------------------------------------------- Thu May 11 00:30:26 UTC 2023 - Stefan Brüns <stefan.bruens@rwth-aachen.de> - Update to version 9.6: * Dependencies + SCIP v801 -> v803 (note: now uses an OSI compatible license) + abseil 20220623.1 -> 20230105.0 + Protobuf v21.5 -> v21.12 + SWIG 4.1.1 * PDLP + Add python wrapper. * CP-SAT + Performance improvements. * GLOP + Tweak presolve. * ModelBuilder + Python: Improve numpy support. * Bazel + Add pybind11 support. + Add java wrapper support. * Routing + Few improvements (local search) * Known Issues: + CP-SAT: Ignoring pseudo_costs subsolver returns Invalid parameters. (#3706) - Update to version 9.5: * CP-SAT + Presolve improvements: max(array), Boolean constraints, linear constraints. + Interleaved search should be deterministic in parallel. + Linear cuts: cleanup square and int_prod cuts; rewrite cut pipeline. + Fingerprint input model and solution (visible in the log). + Scheduling improvements + The usual bunch of bugfixes (crash during presolve, crash in cuts, infeasible solutions, model infeasible in LNS). * GLOP + Speedup by rewriting the linear algebra, as well as the pivot selection rule * Linear Solver + add knapsack_interface.cc. + Move model_builder API under the linear_solver directory (headers and samples). + Add support for Gurobi 10. * Routing + Liberate few parser for various routing challenge. - Drop obsolete patches: * do_not_call_pdlp_solve_test.patch * 0003-Reuse-common-add_cxx_example-function-for-Sat-Runner.patch - Update patches: * 0001-Only-add-relevant-directories-to-sample-RUNPATHs.patch * 0002-Only-add-relevant-directories-to-flatzinc-library-ex.patch * 0003-Only-add-relevant-directories-to-sat_solver-RUNPATHs.patch - Use PIP_NO_INDEX instead of 0001-Do-not-try-to-download-ortools-wheel.patch ------------------------------------------------------------------- Fri Nov 25 12:12:32 UTC 2022 - Stefan Brüns <stefan.bruens@rwth-aachen.de> - Fix build with SWIG 4.1 ------------------------------------------------------------------- Sat Sep 17 16:21:13 UTC 2022 - Stefan Brüns <stefan.bruens@rwth-aachen.de> - Update to version 9.4: * Graph + Split ortools.graph.pywrapgraph into: - ortools.graph.python.linear_sum_assignment - ortools.graph.python.max_flow - ortools.graph.python.min_cost_flow This allows using numpy to speed up the setup of the problems. * CP-SAT + Some improvement on: - scheduling (propagation, cuts, lower bounds) - MaxSAT (presolve, core based heuristics) - MIP performance (presolve, cuts) - Drop upstream patches: * fix_re2_string_view.patch * 0001-Build-Python-modules-as-CMake-MODULEs.patch * fix_malformed_Cpp.patch * 0001-Set-SWIGWORDSIZE-dependent-on-architecture-bitness.patch - Add patches: * do_not_call_pdlp_solve_test.patch * 0003-Reuse-common-add_cxx_example-function-for-Sat-Runner.patch ------------------------------------------------------------------- Fri Jul 15 12:31:32 UTC 2022 - Stefan Brüns <stefan.bruens@rwth-aachen.de> - Fix failing builds due to stricter RUNPATH checks, add * 0001-Only-add-relevant-directories-to-sample-RUNPATHs.patch * 0002-Only-add-relevant-directories-to-flatzinc-library-ex.patch ------------------------------------------------------------------- Sun May 29 14:28:49 UTC 2022 - Stefan Brüns <stefan.bruens@rwth-aachen.de> - Fix failing build with GCC 12, add fix_malformed_Cpp.patch - Fix build on 32bit archs, allow tests to fail - Add _constraints to avoid no-space-left errors ------------------------------------------------------------------- Sun Apr 24 17:23:49 UTC 2022 - Stefan Brüns <stefan.bruens@rwth-aachen.de> - Initial package version (9.3) - Add fix_re2_string_view.patch - Add 0001-Build-Python-modules-as-CMake-MODULEs.patch
