传说古罗马时代,亚历山大城有一位精通数学和物理的学者,名叫海伦。一天,一位罗马将军专程去拜访他,向他请教一个百思不得其解的问题:将军每天从军营A出发,先到河边C处饮马,然后再去同侧的B地开会,应怎样走,才能使路程最短?这就是著名的将军饮马问题。 Legend has it that in ancient Rome, there was a master in mathematics and physics in Alexandria, named Helen. One day a Roman general made a special trip to visit him and asked him a baffled question: The general set out daily from barracks A, first to the C at the river to drink horses, then to the same side of B to meet and How to make the shortest possible distance? This is the famous question of generals drinking horses.
