It has mainly actions as follows: accumulating steel wire; sending steel wire; drawing steel wire; clipping; tighten; squeezing flat; regulating position of strapper, etc; using annealed rod of φ6.5,φ6.0 or hot-finished rod ofφ6.0 directly as strapping steel wire; it straps and tightens for 720°,and then squeezing flat to make sure that it straps firm and not easily loose.

它具有如下主要动作：蓄丝、送丝、抽丝、剪断、拧紧、挤平、打捆机位置调节等；使用φ6.5，φ6.0的退火盘条或直接采用φ6.0的热轧盘条作捆丝；其捆结拧紧720°，然后挤平，保证了捆结牢固，不易松脱。

Among many research problems in bioinformatics, the shortest superstring problem has wide applications in many research areas, such as DNA sequencing and data compression.

在解决NP-hard的问题上，近代有许多最佳化方法被探讨，包括了：蚂蚁演算法、基因演算法、模拟退火法、或一些启发式演算法等等。

Especially the hybrid particle swarm optimization algorithm with across strategy and mutation strategy is simple and effective.
