bluedistro / Graph-Traversal

A fine-tuned visual implementation of Informed and Uninformed Search Algorithms such as Breadth First Search, Depth First Search, Uniform Cost Search, A* Search, Greedy First Search

Searcheron

A practical demonstration of graph traversals using cities in Ghana as examples. Informed Searching Algorithms implemented include:

• Depth First Search (DFS)
• Breadth First Search (BFS)
• Uniform Cost Search (UCS)

Uninformed Searching Algorithms implemented also include:

• Greedy Best First Search (GBFS)
• A* Searching Algorithm (A*A)

Maps to be traversed are in two sections:

1. A less populated (simple) map
2. A much complex map

Cities in the Simple Map

• Accra
• Tema
• Achimota
• Kasoa
• Dansoman
• Mamprobi
• Kaneshie
• Boduase
• Mankessim

Cities in the Extended Map

• Accra
• Tema
• Achimota
• Kasoa
• Dansoman
• Mamprobi
• Kaneshie
• Boduase
• Mankessim
• Korle Gono
• James Town
• Russia
• Bubuashie
• Tesano
• Kakum
• Elmina
• Cape Coast
• Takoradi

All these cities are goal states and the algorithms find paths to these goal states

This Program has two run modes:

• Console mode
• Gui mode

How to run the GUI mode

To run the GUI part of the program, run the searcheron.py file.

Simple instructions for running in console mode

To run the console part of the program, run the console_test.py file

Requirements

• Python 2.7 - Code was only tested in Python2.7. I cannot confirm if it run in other Python Versions or not.
• PyQt4 - (How to install PyQt4 in Python2.7 can be found in requirements.txt file)
