Fibonacci 通项公式:

Fibonacci Heap 是计算机算法中最小堆有序树的集合Decrease-keyO(1)，相比比二项堆O(lgn)进步巨大.

Golden mean:The golden mean is a ratio that is based off the number phi, (1.61803398874). This ratio is commonly found throughout design, architecture and nature. It is a valued design relationship that allows the content in any medium to be proportionally supported by one another.

The graphic on the down is a visual reference to the golden mean ratio. It is based off the integer sequence: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144…. Design layouts that use the golden mean as a basis grid show content in a natural and pleasing way.

黄金比例(来自维基百科):

黄金分割奇妙之处，在于其倒数为自身减1，即：1.618...的倒数为{\displaystyle 0.618\ldots =1.618\ldots -1}，并时常被称为“黄金比例共轭”
