It can be shown that this recursive solution takes exponentialtime to run.
可以证明，这种递归解法需要耗费指数级的时间。

Non-Linear Least Squares were used to estimate the exponentialtime model.
非线性最小二乘法用于估算指数时间模型。

In this paper, we introduce a new scheduling model in which both exponentialtime-dependent learning effect and position-based learning effect exist simultaneously.
