主要讨论一类能表示成最大值函数、最小值函数的分段函数的初等性。
The elementary properties of a sort of separate function which can be described maximum function or minimal function are researched.
第一部分说明所找到的解决方案是整型优化的，为目标函数找到的最小值是23。
The first section says that the solution found is integer optimal, and that the value found for the objective function is 23, a minimum.
但是只能通过递归模板或者扩展函数来完成其他两种常见的操作：求最大值和最小值。
But, you can only accomplish two other popular operations on a set of Numbers, finding the minimum and maximum, by a recursive template or extension function.
