If you are using the Evolutionary Solving method or the multistart methods for global optimization, and you have checked the Require Bounds on Variables check box in the Solver Options dialog (it is checked by default), this message appears if you have no ...
This message appears if you have both a binary or alldifferent constraint on a decision variable and a <= or >= constraint on the same variable (that is inconsistent with the binary or alldifferent specification), or if the same decision variable ap ...
This message appears if you’ve defined lower and upper bounds on a decision variable, where the lower bound is greater than the upper bound. This (obviously) means there can be no feasible solution, but (depending on the Solving method) Solver will detec ...
A model in which the objective function and all of the constraints (other than integer constraints) are linear functions of the decision variables is called a linear programming (LP) problem. (The term “programming” dates from the 1940s and the disciplin ...
A model in which the objective cell and all of the constraints (other than integer constraints) are linear functions of the decision variables is called a linear programming (LP) problem. Such problems are intrinsically easier to solve than nonlinear (NL ...
The GRG Nonlinear Solving method, like most nonlinear optimization methods, normally can find only a locally optimal solution to a nonlinear, non-convex problem. Solver includes a multistart method that can improve your prospects of finding a globally op ...
The most difficult type of optimization problem to solve is a non-smooth problem (NSP). Such a problem may not only have multiple feasible regions and multiple locally optimal points within each region – because some of the functions are non-smooth or ev ...
Adds a constraint to the current problem. Equivalent to clicking Solver in the Data | Analysis group and then clicking Add in the Solver Parameters dialog box. Before you use this function, you must establish a reference to the Solver add-in. In the Visua ...
Changes an existing constraint. Equivalent to clicking Solver in the Data | Analysis group and then clicking Change in the Solver Parameters dialog box. Before you use this function, you must establish a reference to the Solver add-in. In the Visual Basic ...
Deletes an existing constraint. Equivalent to clicking Solver in the Data | Analysis group and then clicking Delete in the Solver Parameters dialog box. Before you use this function, you must establish a reference to the Solver add-in. In the Visual Basic ...
