Locate Data Analysis ToolPak or Solver on the Data tab.Note The Solver add-in is not enabled by default. Click the Data Analysis ToolPak or Solver option to enable it. Click Tools, and then click Add-Ins.In the Visual Basic Editor, with a module active, click References on the Tools menu, and then select Solver under Available References. After the Solver add-in is installed, you must establish a reference to the Solver add-in. For information about how to do that, see Using the Solver VBA Functions.

In the Add-Ins box, check the Analysis ToolPak check box, and then click OK. If you're using Excel for Mac, in the file menu go to Tools > Excel Add-ins. In the Manage.In the Manage box, select Excel Add-ins and then click Go. The maximum number of iterations Solver will use in solving the problem. The value must be a positive integer.Iterations Optional Variant. The maximum amount of time (in seconds) Solver will spend solving the problem. SolverOptions( MaxTime, Iterations, Precision, AssumeLinear, StepThru, Estimates, Derivatives, SearchOption, IntTolerance, Scaling, Convergence, AssumeNonNeg, PopulationSize, RandomSeed, MultiStart, RequireBounds, MutationRate, MaxSubproblems, MaxIntegerSols, SolveWithout, MaxTimeNoImp)MaxTime Optional Variant. Step 3: Clear any existing solver. Step 2: Open the solver dialog box (Tools > Solver. This speeds the solution process, but it should be used only if all the relationships in the model are linear. True to have Solver assume that the underlying model is linear. In general, the higher the degree of precision you specify (the smaller the number), the more time Solver will take to reach solutions.AssumeLinear Optional Variant. A smaller number of decimal places (for example, 0.0001) indicates a lower degree of precision. The default precision is 0.000001. A number between 0 (zero) and 1 that specifies the degree of precisionwith which constraints (including integer constraints) must be satisfied. False to not have Solver pause at each trial solution. You can pass Solver a macro to run at each pause by using the ShowRef argument of the SolverSolve function. True to have Solver pause at each trial solution. The default value is 1 (tangent estimates).Derivatives Optional Variant. Quadratic estimates use quadratic extrapolation this may improve the results for highly nonlinear problems. Tangent estimates use linear extrapolation from a tangent vector. Specifies the approach used to obtain initial estimates of the basic variables in each one-dimensional search: 1 represents tangent estimates, and 2 represents quadratic estimates. Use the Search options to specify the search algorithm that will be used at each iteration to decide which direction to search in: 1 represents the Newton search method, and 2 represents the conjugate search method. The default value is 1 (forward differencing).SearchOption Optional Variant. With constraints whose values change rapidly near their limits, you should use central differencing. Central differencing requires more worksheet recalculations, but it may help with problems that generate a message saying that Solver could not improve the solution. A larger percentage tolerance would tend to speed up the solution process.Scaling Optional Variant. This argument applies only if integer constraints have been defined it specifies that Solver can stop if it has found a feasible integer solution whose objective is within this percentage of the best known bound on the objective of the true integer optimal solution. A decimal number between 0 (zero) and 100 that specifies the Integer Optimality percentage tolerance. A number between 0 (zero) and 1 that specifies the convergence tolerance for the GRG Nonlinear Solving and Evolutionary Solving methods. The default value is True.Convergence Optional Variant. If this option is False, Solver will perform its computations with the original values of the objective and constraints. True to have Solver assume a lower limit of 0 (zero) for all decision variable cells that do not have explicit lower limits in the Constraint list box (the cells must contain nonnegative values). False to have Solver use only the limits specified in the Constraint list box.PopulationSize Optional Variant. True to have Solver assume a lower limit of 0 (zero) for all decision variable cells that do not have explicit lower limits in the Constraint list box (the cells must contain nonnegative values). All constraints are satisfied."AssumeNonNeg Optional Variant. In both cases, Solver displays the message "Solver converged to the current solution. For the Evolutionary method, when 99% or more of the members of the population have "fitness" values whose relative, that is percentage, difference is less than this tolerance, Solver stops. Have Solver As Add In For Excel Generator Each TimeTrue to cause the Evolutionary Solving method and the multistart method to return immediately from a call to SolverSolve with a value of 18 if any of the variables do not have both lower and upper bounds defined. False to have Solver run the GRG Solving method only once, without multistart, when SolverSolve is called.RequireBounds Optional Variant. True to have Solver use multistart method for global optimization with the GRG Nonlinear Solving method, when SolverSolve is called. A zero value specifies that Solver should use a different seed for the random number generator each time it runs, which may yield different solutions each time it is run on a model that has not changed.MultiStart Optional Variant. This means that Solver will find the same solution each time it is run on a model that has not changed. A positive integer specifies a fixed seed for the random number generator used by the Evolutionary Solving method and the multistart method for global optimization. Buku persamaan ic dan transistor amplifierThe value must be a positive integer.MaxIntegerSols Optional Variant. The maximum number of subproblems Solver will explore in problems with integer constraints, and problems solved via the Evolutionary Solving method. A higher Mutation rate tends to increase the diversity of the population, and may yield better solutions.MaxSubproblems Optional Variant. A number between 0 (zero) and 1 that specifies the rate at which the Evolutionary Solving method will make "mutations" to existing population members. ExampleThis example sets the Precision option to. The value must be a positive integer. When the Evolutionary Solving method is used, the maximum amount of time (in seconds) Solver will continue solving without finding significantly improved solutions to add to the population. False to have Solver use the integer constraints in solving the problem.MaxTimeNoImp Optional Variant. True to have Solver ignore any integer constraints and solve the "relaxation" of the problem. The value must be a positive integer.SolveWithout Optional Variant.
