This message appears when (i) Solver has completed the maximum number of iterations, or trial solutions, allowed in the Iterations box in the Solver Options dialog and (ii) you clicked the Stop button when Solver displayed the Show Trial Solution dialog. ...
This message appears only if you press ESC to display the Show Trial Solution dialog, and then click the Stop button. When you do this, no reports are available in the Solver Results dialog. ...
This message appears when Solver determines that your model is too large for the Solving method you have selected. All Solving methods are limited to 200 decision variables; the GRG Nonlinear and Evolutionary Solving methods are also limited to 100 const ...
This message appears when (i) Solver has run for the maximum time (number of seconds) allowed in the Maximum Time box in the Solver Options dialog and (ii) you clicked the Stop button when Solver displayed the Show Trial Solution dialog. You may increase ...
This message will appear if Solver cannot allocate the memory it needs to solve the problem; it is very unlikely to appear on modern PCs. Also, since Microsoft Windows supports a “virtual memory” much larger than your available RAM by swapping data to yo ...
If you are solving a mixed-integer programming problem (any problem with integer constraints) with a non-zero value for the Integer Optimality % option in the Solver Options dialog, Solver has found a solution satisfying the constraints (including the int ...
If you are using the Evolutionary Solving method, this message appears when (i) Solver has found the number of feasible solutions allowed by the Maximum Feasible Solutions option in the Solver Options dialog and (ii) you clicked the Stop button when Solve ...
Users who solve problems with integer constraints occasionally report that “Solver claims it found an optimal solution, but I manually found an even better solution.” Solver now stops with the message “Solver found an integer solution within tolerance” i ...
Nonlinear optimization problems are intrinsically more difficult to solve than linear problems, and there are fewer guarantees about what kind of solution Solver can find. If your smooth nonlinear problem is convex, Solver will normally find the globally ...
Solver’s multistart methods for global optimization can overcome some of the limitations of the GRG Solving method alone, but they are not a panacea. The multistart methods will automatically run the GRG method from a number of starting points and will d ...
