有两位数学家最近找到了一种在计算机上求解大系统线性方程的方法,这一成果可以很快地用于诸多科学领域,如气象预测和建立经济模型。在这一进展中,这两位科学家重新解决了一个持续了五十年之久的难题。麻省理工学院的罗奈德·赖维斯特(RonaldRivest)描述这项新的成果是“十分惊人的,它将使求解速度大大加快,看来很可能大大地推动这方面的实际工作”。此外,赖维斯特指出,这种方法在理论上是很有意义的,他断言“这是一项真正的成果”。 Two mathematicians recently found a way to solve large-system linear equations on a computer, a result that can quickly be used in many scientific fields, such as weather prediction and economic modeling. In this progress, the two scientists have re-solved a difficult problem that lasted for 50 years. Ronald Rivest at MIT describes the new achievement as “phenomenal, and it will make the solution much faster, and it seems likely to greatly boost the practical work in this area.” In addition, Revest points out that this approach is theoretically significant and asserts that “this is a real achievement.”
