取一维立方体中一个有限的基数点集,取一个可积函数。的QMC积分是中每个点的值的平均值,它近似于立方体的积分。假设它是由一个矢量空间通过数字网络构造的,具有数字精度。作为Josef Dick方法的一位数离散化版本,我们引入了的Walsh优值图(WAFOM),它满足一个kokma - hlawka型不等式,即QMC积分误差由的次光滑性有界,其中是一个仅依赖于的常数。
Letbe a finite point set of cardinalityin an-dimensional cube, and letbe an integrable function. A QMC integral ofbyis the average of values ofat each point in, which approximates the integral ofover the cube. Assume thatis constructed from an-vector spaceby means of a digital net with-digit precision. As an-digit discretized version of Josef Dick’s method, we introduce the Walsh figure of merit (WAFOM)of, which satisfies a Koksma-Hlawka type inequality, namely, QMC integration error is bounded byunder-smoothness of, whereis a constant depending only on.
