See Output Format section for more detail. TCOL1 format is convenient to plot transient views of solution variables at a desired spatial locations. XCOL1 format is convenient to plot snapshots of solution variables at a desired time values. TCOL1 Column 1 of the result array will contain the output temporal points.A block of columns for the solution variables at each output spatial point will be reported in order following column 1. XCOL1 Column 1 of the results array will contain the output spatial points.A block of columns for the solution variables at each output temporal point will be reported in order following column 1. The allocated results array must have sufficient columns to hold output.

include first and second derivatives ( u 1,x, u 2,x.),( u 1,xx, u 2,xx.) in output.

include first derivatives ( u 1,x, u 2,x.) in output.

This example displays a message if you have not used Solver on Sheet1. If SheetName is omitted, this sheet is assumed to be the active sheet. The name of the sheet that contains the Solver model for which you want information. The Maximum Time without Improvement option(Evolutionary tab). The Ignore Integer Constraints option(All Methods tab). The Max Feasible Solutions option(All Methods tab). The Max Subproblems option(All Methods tab).

The Mutation Rate option (Evolutionary tab). True if the Require Bounds on Variables check box is selected False if it is cleared (GRG Nonlinear tab and Evolutionary tab). True if the Use Multistart check box is selected False if it is cleared (GRG Nonlinear tab). The Random Seed option(GRG Nonlinear tab and Evolutionary tab). The Population Size option (GRG Nonlinear tab and Evolutionary tab). The Convergence tolerance (GRG Nonlinear tab and Evolutionary tab).

(In Excel 2009, this option does not appear in the Solver Options dialog box.)Ī number corresponding to the Derivatives option in the GRG Nonlinear tab: 1 represents Forward, and 2 represents Central (GRG Nonlinear tab).Ī number corresponding to the type of search: 1 represents Newton, and 2 represents Conjugate. True if the Use Automatic Scaling check box is selected False if it is cleared (All Methods tab).Ī number corresponding to the type of estimates: 1 represents Tangent, and 2 represents Quadratic. True if the Show Iteration Results check box is selected False if it is cleared (All Methods tab). The Integer Optimality (%) option (All Methods tab). The Constraint Precision option (All Methods tab). The Max Time (Seconds) option (All Methods tab). The following settings are specified in the Solver Options dialog box. True if the Make Unconstrained Variables Non-Negative check box is selected False if it is cleared. True if the Simple LP Solving method is selected False if another Solving method is selected. The reference (as a multiple reference, if necessary) in the By Changing Variable Cells box.Īn array of the left sides of the constraints, in text form.Īn array of numbers corresponding to the relationships between the left and right sides of the constraints: 1 represents =, 4 represents int, 5 represents bin, and 6 represents dif.Īn array of the right sides of the constraints, in text form. The reference in the Set Objective box, or the #N/A error value if Solver has not been used on the active sheet.Ī number corresponding to the Equal To option: 1 represents Max, 2 represents Min, and 3 represents Value Of. The following settings are specified in the Solver Parameters dialog box.

A number specifying the type of information you want. If Solver.xlam does not appear under Available References, click Browse and open Solver.xlam in the \office14\library\Solver subfolder. In the Visual Basic Editor, with a module active, click References on the Tools menu, and then select the Solver.xlam check box under Available References. The settings are specified in the Solver Parameters and Solver Options dialog boxes.īefore you use this function, you must establish a reference to the Solver add-in. Returns information about current settings for Solver.
