Instead of using Excel to host your model we can build your model into a normal Windows program interface along with the GASolver math; then compile them both into an efficient package that can then be installed on any normal MS-Windows computer.

These pre-packages use the same math as GASolver but run as standalone programs that do not need MS-Excel.

If you are interested in a packaged version of our solver to work in partnership with your own model then email us at GASolver@yearstretch.com

If you tend to solve the same model over and over again for different conditions then a packaged version will save you time.

If you want to give your staff, or your clients, access to a particular solver but prefer to hide the math IP or wish them to be able to use a ruggedised version then a packaged solution is the answer.

Advantages:

• The speed of the packaged solver exceeds that of GASolver within Excel by an order of magnitude or more.
• The math for your model is hidden from the user, in Excel is it available for all to see.
• The program can be branded as your own company's product if you require to distribute solution finders  to your customers.
• The program can be provided with only the minimum user controls for safe and sure use by non-expert users.

The packaged version of Example 3 is available for free download so to evaluate an example of pre-packaged solver download the program below.
