Recently, MIT researchers are creating a time planning algorithm, it can calculate the probability of completing projects, while providing more likely scenarios. This ground is called "great Siri" (better Siri) software can help people make all the plans, such as long distance driving, air travel and even billions of dollars of NASA (United States NASA) launch plans.
Virtual Assistant on our phones or tablets can use maps and navigation tools to forecast travel time, but it has many limitations, but because it did not predict the details of delay time in the Middle, that is, if we meet in the Middle delays, traffic jams and other inconveniences, the virtual assistant told us that three-hour trip will turn into four or five hours.
And this from Brian Williams and MIT researchers created algorithm can effectively address this limitation, which users can then predict the delay time in the middle. There is no doubt that whether it is complex or simple car trip itinerary contains many uncertainties, and "great Siri" would consider the uncertainties, and predicting specific time for each and every user to ensure complete plan before the deadline.
If it believes that you may not be able to complete your plan, then it will use weighted graph (a mathematical language constructs) to propose under the existing scheme, changing the minimum, but a high likelihood of winning a workable plan.
For example, your existing plan is a two-hour drive after being friends, at your favorite restaurants and dine with him, and then at a specific time to an important meeting. "Great Siri" (you can put it on your mobile phone) might tell you: project success rate of only 50%, but if you start 20 minutes in advance or choose another restaurant for dinner, then your success rate will increase to 99%.
William developed this software to make more accurate budget reasons: it combines a range of complex factors, such as the entire distance by mile segment, and calculate the uncertainty in each section. Even today's most advanced processors, to complete this task is not easy. But William and his team use a special method to simplify the calculation.
"We see this idea called ' risk-sharing ', we will risk taking into account the plan to ensure people to develop feasible plans. "Members of the team, said Cheng fang of MIT graduates.
In fact, users can also show their own acceptable "failure". In the above example, you can say you don't mind five minutes late or eat a little bit faster. These soft factors taken into account for the calculation much easier.
"Great Siri" private trip not only help people, it can also benefit other big plans. In fact, NASA and the Woods Hole Oceanographic Institution already use similar methods to make them more complex long-term plan; transport companies also use this software to ensure train and bus to reach their destination on time.

Therefore, it is "better Siri" the intimate Assistant, I believe we will never "just luck" schedule.
