In addition , in consideration of the non - convex and non - concave nature of the combinational optimization sub - problem , the branch and bound technique is adopted to obtain or approximate the global optimal solution 针对组合优化子问题的非凸非凹性,采用分支定界法,以求得或接近全局最优解。
But , retiming should be used together with existing combinational optimization techniques and form an optimizational flow in practical circuitry system to exert fully the advantage of both 而实际的电路优化系统应该将重定时算法与其它组合优化方法结合在一个优化流中,充分发挥二者的优势。
Description : a synthesized poetic & calligraphic exhibition , using the curvature appearance and the combinational construction of words with the help of spatial installations to present poetry in multiple scenes 简述:综合书法以线条、造形、文字结构以及空间实物藉以表现诗的易象与时空变化场景。
So , with the reciprocal mass of this combinational equipment , the dynamic unbalance of the crank - connecting rod mechanism has the special status in the field of the unbalance theory 由于有往复质量的影响,曲柄连杆机构不可能达到完全的平衡,有其特殊性,因此其理论在动平衡领域内占有特殊地位。
The method of optimization is classified into two categories : ( 1 ) combinational optimization method , which is the optimizational method of combinational circuit is directly used for the sequence circuit 优化的方法大致可分为两类: ( 1 )组合优化方法,即将组合电路的优化方法直接用于时序电路。
