计算复杂性的研究告诉我们,有些问题本质上是困难的,无论我们的算法多么聪明。
"The study of computational complexity teaches us that some problems are inherently difficult, no matter how clever our algorithms are."
"Books are the quietest and most constant of friends; they are the most accessible and wisest of counselors, and the most patient of teachers."
预测未来的最好方法就是创造未来。
