MOSEK Changelog

20231117

  • MP update: fixed graceful exit on Ctrl-C from AMPL in Linux and fixed issue with reading text-format NL files

20231103

  • Improved translation of logical constraints: inlining of nested disjunctions and conjunctions; fewer auxiliary binary variables.

20231017

  • Fixed a bug in NL reader on Windows.

  • Print a warning when not all quadratic constraints have been converted to cones.

20230919

  • mp_options. Receive mp_options from AMPL (for all MP solvers). They are parsed before (solvername)_options.

  • Solution checking: relative tolerance sol:chk:feastolrel; options sol:chk:round, sol:chk:prec.

20230831

  • Solution checking, options sol:chk:* (experimental).

  • Preprocess And/Or constraints.

20230817

  • Fixed a bug causing repeated names for auxiliary variables and constraints.

  • Option values can be assigned without ‘=’.

  • Fixed a bug where equivalent conditional comparisons were not unified.

20230726

  • Fixed inequalities of integer expressions with non-integer constants, see test_int_non_int.mod.

20230724

  • option [solver_]auxfiles rc; transfers names of variables and linear constraints into the model; (solver)_options ‘cvt:names=0-3’ controls names.

20230621

  • Fix quadratic objective with repeated subexpressions.

20230616

  • Changes in MP.

20230531

  • Cones: recognize (affine_expr) >= y * exp(z/y) as exponential cone.

  • Cones: recognize xy >= 1 as rotated SOC.

  • Wrong solver options are gracefully reported via solve_message.

20230515

  • Exponential cones. MP driver recognizes exponential cones from their algebraic representation and passes them to Mosek.

20230505

  • Updated Mosek library to version 10.0.43. It includes a number of bug fixes, including a numerical problem that could occur with disjunctive constraints

20230424

  • Changes in the MP library: added variable names support and removed spurious starting solution

20230330

  • Removed the message on missing dual solution for MIP.

20230321

  • Recognition of second-order conic constraints from algebraic representations.

  • First release in the AMPL bundle.

20220420

  • First release of mock driver.
