Question

Determine which is the fastest algorithm

Answer 1

Answer:

fastest search algorithm

Binary Search is the fastest and most efficient searching technique.

Answer 2

Answer:

Now the problem is, the shortest route is not always the fastest one, because of traffic jams or other factors.

For example:

1-2 is known to have frequent traffic jams, so it should be avoided.

Suddenly a car accident happens along 4-3, so it should be avoided too.

Etc...

So probably we can speed on the route 1-4-5, because of no traffic jams/accidents, so will arrive at 5 faster.

Well that's the general idea, and I haven't think about more details yet.
