In order to improve the performance limitation of original Snake model, many researchers have proposed some improved Snake models, for example, the Balloon model, the distance model, the GVF model, and the Greedy algorithm, etc.
针对原始Snake模型的一些性能缺陷,一些学者提出了改进方法,比如气球模型、距离模型、GVF模型、贪婪算法等。

So he's packing and unpacking, packing and unpacking, trying all possible combinations of objects that will obey the constraint. And then choosing the winner. Well, this is like an algorithm we've seen before. It's not greedy.
因此它不断装包和清包,尝试了所有满足约束条件的物品组合,最后选择最优者,这很像我们以前看过的一个算法,这不是贪婪算法。
