Implemented BFS, DFS and A*



To compile this project, use the following command:

g++ -o search main.cpp



Then you can run it:

./search



The input is loaded from a input file in.txt



Here is the format of the input file:

The first line of the input file shoud contain two chars indicate the source and destination city for breadth first and depth first algorithm.

The second line of input file shoud be an integer m indicate the number of connections for the map.

Following m lines describe the map, each line represents to one connection in this form: dist city1 city2, which means there is a connection between city1 and city2 with the distance dist.

The following input are for A*

The following line contains two chars indicate the source and destination city for A* algorithm.

Then there is an integer h indicate the number of heuristic.

The following h lines is in the form: city dist which means the straight-line distance from the city to B is dist.
