The duration range is the difference between the shortest and longest rhythm used. Zoom lenses are often described by the ratio of their longest to shortest focal lengths. The distance is the length of a shortest path connecting the vertices. This is the shortest and the oldest railway route to Vladivostok. The tail is the shortest of any big cat, at in length. It is one of the surest and shortest means. This is the simplest mechanism and generally the shortest, lightest, and smoothest pull available. In short, it attempts to screen candidates for certain jobs within the shortest possible time. The object is to accomplish this in the shortest time. This is easy to do as shortest path problems are relatively easy to solve. We also need to know what the actual shortest path is. The winner is the person who completes the course in the shortest time. This condition defines the curve that the body slides along in the shortest time possible. The second is the shortest and most simply constructed of the marches. This model can be shown to be able to compute shortest paths.
