MP update: fixed graceful exit on Ctrl-C from AMPL in Linux and fixed issue with reading text-format NL files
Improved translation of logical constraints: inlining of nested disjunctions and conjunctions; fewer auxiliary binary variables.
Fixed a bug in NL reader on Windows.
Print a warning when not all quadratic constraints have been converted to cones.
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.
Solution checking, options sol:chk:* (experimental).
Preprocess And/Or constraints.
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.
Fixed inequalities of integer expressions with non-integer constants, see test_int_non_int.mod.
option [solver_]auxfiles rc; transfers names of variables and linear constraints into the model; (solver)_options ‘cvt:names=0-3’ controls names.
Fix quadratic objective with repeated subexpressions.
Changes in MP.
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.
Exponential cones. MP driver recognizes exponential cones from their algebraic representation and passes them to Mosek.
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
Changes in the MP library: added variable names support and removed spurious starting solution
Removed the message on missing dual solution for MIP.
Recognition of second-order conic constraints from algebraic representations.
First release in the AMPL bundle.
First release of mock driver.
