The Art of War

The art of war(손자병법) is a Chinese military treatise that was written by Sun Tzu(손무) in the 6th century BC. The Art of War is one of the oldest and most successful books on military strategy in the world.

If you know your enemy and yourself, you can win every battle.

This is one piece of his Analects. As he said, he always emphasize military intelligence.

As focusing that Sun Tzu tried to figure out an optimum solution under many constraints like a food capacity and a number of soldiers, we call the Art of War "Operations research" in modern science terminology. But, Sun Tzu didn't focus on the tactics, also on person's mental attitude conducting a war.
