< li > Add the new Foo parameter in the DoubleParam or IntegerParam enum.< / li >

< li > Decide if the wrapper should define a default value for it: yes if it controls the properties of the solution (example: tolerances) or if it consistently improves performance, no otherwise. If yes, define kDefaultFoo.< / li >
< li > Add a foo_value_ member and, if no default value is defined, a foo_is_default_ member.< / li >

< li > In class < a class = "el" href = "classoperations__research_1_1MPSolverInterface.html" > MPSolverInterface< / a > , add a virtual method SetFoo, add it to SetCommonParameters or SetMIPParameters, and implement it for each solver.
