  • Ticket #20302 – Description

    v88 v94  
    1313 - #20462: `MixedIntegerLinearProgram`/`MIPVariable`: `get_min`, `set_min`, `get_max`, `set_max` are broken
    1414 - #20602: Deprecate `MixedIntegerLinearProgram.gen()`, `__call__`, `linear_function`, which do not do anything useful; add `default_variable` method
    15  - #20656: `MixedIntegerLinearProgram`: Remove `_variables` dictionary
    16  - #20657: More fixes for copying a MIP and the `MIPVariable`s created by `new_variable`

    2018 - #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
