Detailed Description

Gurobi specific parameters for solving. See https://www.gurobi.com/documentation/9.1/refman/parameters.html for a list of possible parameters.

Example use: GurobiParameters gurobi; gurobi.param_values["BarIterLimit"] = "10";

With Gurobi, the order that parameters are applied can have an impact in rare situations. Parameters are applied in the following order:

• LogToConsole is set from SolveParameters.enable_output.
• Any common parameters not overwritten by GurobiParameters.
• param_values in iteration order (insertion order). We set LogToConsole first because setting other parameters can generate output.
