New type of cryptography that can better resist "dictionary attacks"Cryptographers in China have have developed a new type of cryptography that can better resist so-called offline "dictionary attacks", denial of service (DoS) hacks, and cracks involving eavesdroppers. Their approach, reported in the International Journal of Electronic Security and Digital Forensics, extends and improves a type of cryptography that uses an intractable mathematical problem as its basis.

The most accurate way to answer this question is to measure every possible route, then determine which one is shortest. However, this method becomes unfeasible when there are too many cities on the salesman's tour. Jeff Jones and Andrew Adamatzky of the University of the West of England have discovered that they can use a virtual shrinking blob to find a reasonable solution.

The question was one of seven millennium problems set by the Clay Mathematical Institute (CMI) in Cambridge, Massachusetts as being among the most difficult to solve.

Likewise, drawing or making a pictorial representation relating to the also contributed to its solution.
