Abstract
In a computer having a multithreaded operating system, a road-mapping program begins a best-route calculation in the background such that much of the calculation is completed before the user finishes providing inputs. In this manner, the user's perceived calculation time is shortened. The user is allowed to input any of a number of variables related to the best-route calculation. The calculation can be initiated without all of the variables necessary to finish it. The calculation is initiated upon the receipt of a predetermined variable, and predicts values for the unreceived variables. As each variable is received, the invention confirms that the predicted value for that variable is confirmed as correct. If the predicted value is incorrect, the calculation is restarted based on the actual value of that variable, in combination with predictions for the variables which have still not been received.
