The applicable condition of generalized inverse approximate algorithm and the condition that the generalized inverse solution is just the accurate solution are discussed theoretically and given 通过理论分析给出了广义逆理论近似算法的适用条件和广义逆解答是精确解答的条件。
The singly scattered radiant intensity is computed analytically without approximation , preserving more of the angular dependence in the radiance than other approximation solutions 单次散射是可以精确求解的,没有作任何近似,这就使得与其他近似算法相比,该算法包含有更多的角度信息。
Three methods that are approximate arithemeti inverse iteration and trial means have put forward . then three methods have been applied for analysis of a example successfully 提出了三种形状确定的方法? ?近似算法、逆迭代法及试算法。并通过算例进行了对比分析,证明了三种方法的有效性。
A approximate algorithm is presented by which satisfactory results of two dimensional optimal layout belonged to np complete problems can be obtained efficiently and rapidly 摘要针对理论上属于np完全问题的二维矩形件优化排样问题,构建了一个排样效率高、计算速度快和排样效果好的一种近似算法。
But this algorithm do not guarantee the minimization of the set of vertex cover , which mean while do not guarantee it can be fixed that all of fault chips which should be fixed 但该算法的缺点在于不能保证求出顶点覆盖的最优解。也就是说,当一片芯片在事实上是可修复时却有可能在近似算法中得到不可修复的结论。
