Ticket #20302 – Description
v88 v94 13 13 - #20462: `MixedIntegerLinearProgram`/`MIPVariable`: `get_min`, `set_min`, `get_max`, `set_max` are broken 14 14 - #20602: Deprecate `MixedIntegerLinearProgram.gen()`, `__call__`, `linear_function`, which do not do anything useful; add `default_variable` method 15 - #20656: `MixedIntegerLinearProgram`: Remove `_variables` dictionary16 - #20657: More fixes for copying a MIP and the `MIPVariable`s created by `new_variable`17 15 18 Frontend wishlist tickets:16 Frontend improvements: 19 17 - #7574: clean up of MIP interface 20 18 - #20406: `get_solver` should allow passing a function (a solver factory) as the solver argument 19 - #15583: `sage.numerical.linear_functions.LinearConstraint` is not a hashable type 20 - #20773: `MixedIntegerLinearProgram.new_variable` could optionally take a "static" list of component indices 21 - #23681: Make _repr_ of MILP more informative 21 22 - #19523: Raise an error when constraints are added to the wrong MILP 22 - #20664: `MixedIntegerLinearProgram`/`MIPVariable` API cleanup 23 - #20773: `MixedIntegerLinearProgram.new_variable` could optionally take a "static" list of component indices 24 - #20331: A `MIPVariable`'s repr should include some useful information 23 - #20664: '''Meta-ticket: `MixedIntegerLinearProgram`/`MIPVariable` API cleanup''' 25 24 - #18733: `MixedIntegerLinearProgram` should support tableau-query methods 26 25 - #18688: `MixedIntegerLinearProgram` should support basis status getting/setting … … 28 27 - #18466: Optimal dual solution of LP from `MixedIntegerLinearProgram` 29 28 - #7300: Display tight constraints 30 - #7790: Setting a default max/min bound when calling `MixedIntegerLinearProgram.new_variable`31 29 - #15356: linear programming enhancements 32 - #15583: `sage.numerical.linear_functions.LinearConstraint` is not a hashable type33 - #23681: Make _repr_ of MILP more informative34 - #26302: `MixedIntegerLinearProgram` should provide a way to get the variables in the order they are provided to the `polyhedron` method35 30 - #26511: MIP frontend/backend using PuLP 36 31
