Threading the right choice?

Im new to threads, therefore im not sure if threads are the right way to approach this.

My program needs to perform a calculation a couple of times, same logik behind it, but with different parameters. The longer the calculation, the closer it will be to the perfect answer. The calculation duration cant be measured beforehanded (from a few seconds to a couple of minutes)

The user wants to have the results in an order (from calculation 1 to X) at certain times. He is satisfied with not the perfect solution as long as it he gets a result. Once he has a solution, he is not interested in the one before (example: he has a not perfect answer from calculation 1 and demands now answer from calculation 2; even if there is a better answer now for calculation 1, he is not interested in it)

Is threading the right way to do this?

Threading sounds like a good approach for this, as you can perform your long-running computation on a background thread while keeping your UI responsive.

In order to satisfy your requirement of having results in an order, you may need a way of stopping threads that are no longer needed. Either abort them (may be extreme), or just signal them to stop and/or return the current result.

Note you may want the threads to periodically check back in with the UI to report progress (% complete), check for any abort requests, etc. Although this depends entirely upon your application and is not necessarily required.
