It is pointed out that valuable approximate algorithms can be obtained for large Numbers of NP hard problems by following the quasi-physical procedure.
这种拟物的方案可为许多NP难度的问题得出有价值的近似算法。

The method of weighted residuals is a mathematic procedure with which approximate solutions can be obtained directly from partial differential equations.
加权残值法是一种可以直接从偏微分方程中求得近似解的数学方法。
