Therefore, in order to make the model more realistic, in this paper, we formulate the long term conflict avoidance problem as a multi objective optimization problem which minimizes the total delay and reduces the number of conflicts simultaneously. As a complex air route networks needs to accommodate thousands of flights, the problem is a large scale combinatorial optimization problem with tightly coupled variables, which make the problem difficult to deal with. Hence, in order to further improve the searching capability of the solution algorithm, a cooperative co evolution (CC) algorithm is also introduced to divide the complex problem into several low dimensional sub problems which are easier to solve.
A PG Key looks like an ordinary USB flash drive. It is small basically 1 inch wide by 1.5 inches wide. The PG Key does not hog a lot of space. What to Get Instead: Anything that remotely practical and a decent value for the money. If you noticed your dad wheelbarrow wobbles, or his favorite work boots have no more tread, or his college alma mater baseball hat is falling apart, go and get him a new replacement. Save him the trouble of a trip to the store.

And he doesn record his side of phone conversations because speech recognition software still isn good enough to provide an accurate transcript. Right now, the wifi enabled scale doesn talk to the program that monitors blood pressure, diet or sleep but such integration will come eventually. Maybe someday it will even link up with toilets that can read shifting microbial populations and warn of impending illness.
The Gates Foundation might be best known for its work on malaria and vaccines. But lately it has also taken an interest in sanitation, for good reason. More than 2.6 billion people in the world don’t have access to clean toilets, and 1.5 million children die each year of diseases that could be prevented with decent sanitation..
