The international container service layout strategy is essentially a kind of conditional extremum issue.
国际集装箱班轮运输航线规划策略，从本质意义上说是一种条件极值问题。
Meanwhile, the differences between the conditional extremum and unconditional extremum in concept and evaluation are pointed.
同时还指出了条件极值和无条件极值在概念上及求法上的一些区别。
In this connection we propose two methods for implementation: to use Lagrange's conditional extremum and the spline function approximation.
为此提出两种实施的方法：利用拉格朗日的条件极值和利用样条函数逼近。
