基于GA的通風(fēng)網(wǎng)絡(luò)圖優(yōu)化繪制算法研究
[Abstract]:In recent years, genetic algorithm (GA) has been developed rapidly as a new random search and optimization algorithm, and has been widely used in many fields. In this paper, the genetic algorithm is used as the main optimization algorithm, and the hierarchical algorithm and the longest path algorithm are combined to study the drawing of mine ventilation network diagram. On the basis of the delamination of the network graph based on the longest path, the sequential coding method based on the node arrangement for the network graph drawing is proposed. According to the actual drawing process of mine ventilation network diagram, the genetic algorithm is used to optimize the node ranking, the mathematical expression of fitness function is described, and the problem of how to reduce the number of branches crossing is studied emphatically. At the same time, on the basis of studying the longest path algorithm, the algorithm of drawing mine ventilation network diagram based on the longest path parallel path method is proposed. Finally, according to the theoretical algorithm, the ventilation network diagram of No. 2 well in Sihe Mine is optimized.
