crossing number meaning in Chinese
交叉数
Examples
- New results for the crossing number of circular graphs
循环图交叉数的新结果 - Consequently , there is urgent need of good algorithm for calculating the crossing number of graph
因此，迫切希望有较好的计算机算法用以计算图的交叉数。 - The crossing number of graph , which is an np - complete problem , has an important theory meaning
图的交叉数问题属于np -困难问题，对它的研究有重要的理论意义。 - In addition , erdos and guythe ' s conjecture about graphs with maximal crossing number is proved incorrect
还证明了erdos和guy关于可能有最大的交叉数的图的猜想不成立。 - Using the algorithm ccn ( calculate crossing number ) invented by us , we investigate the crossing numbers of all graphs for n < 9
利用我们研制的计算图的交叉数的算法ccn ( calculatecrossingnumber ) ，本文对n 9的所有图的交叉数进行了研究。
