A discussion of postorder - traverse binary tree with no - recursive algorithm
遞歸演算法的非遞歸化研究 -
Nevertheless, some indices do not contain all element nodes, many paths need to still be examined in the query ; other indices produce redundant data in the preorder or postorder traversal, this makes the cost of query much more
然而有的索引不包含所有的元素結點，因而在進行查詢時許多路徑仍需要檢測；有的在向前或向後遍歷時產生了大量的冗餘數據，從而造成查詢代價較大。 -
It presents the arithmetic that is achieved by postorder traversing binary tree, which is built from aov diagraph, based on investigating the arithmetic of interchanging between the ladder diagram and instruction list, and the interpretation and execution of plc programming language. the whole software is developed in visual c + + ide with mfc and multi - threads mechanism. the software is well constructed and conforms to a standard of iec61131
在重點研究了編程軟體中梯形圖與指令表程序的轉換演算法以及指令解釋執行的原理和方法的基礎上，提出了由aov有向圖建立二叉樹、並對其進行後序遍歷來實現梯形圖程序與指令表程序轉換的演算法，並給出了演算法在編程軟體中的具體實現。
