[algorithm] Dijkstra双栈算法表达式求值算法 一、原理 Dijkstra所做的一个算法,双栈求值,用两个栈(一个保存运算符,一个用于保存操作数), 表达式由括号,运算符和操作数组成。 (1).将操作数压入操作数栈 (2).将运算符压入运算符栈; (3).忽略左括号; (4).在遇到右括号时候,弹出一个运算符,弹出所需数量...
Geodesic Distance Calculator with Dijkstra Algorithm. Calculates shortest path between two random vertices on a mesh with Dijkstra's Algorithm. Here are some results: PS: Coin3D library didnt included in this project, you need to download it and place under C:/Coin3D or change dependencies of ...
Distance calculator helps the system to find the distance between cities and calculate by traffic in both mile and time. The aim of this study is to provide finding the shortest path for bus routing based on Dijkstra's algorithm (DA). As the basic theory of solving this problem, DA has ...

We have decided to open source our calculator project to the world. Here are some of the features of the code: Implements a lexer, parser, and Dijkstra’s shunting yard algorithm to convert an expression into postfix form. Implements a simple stack machine for parsing these expressions. When ...
With this simple application, you can calculate the shortest paths from a node to the others nodes in a graph, using the Dijkstra Algorithm (also called SPF or Shorthest Path First).The applications of the algorithm are multiple, such as:-Routing protocol on the Internet-Recognition of spoken...
