1. Implementation of A* using Graph-Search
The aim of this project is to design and implement the A* searching technique using
Graph-Search strategy. These steps should be followed:
a. Define an adequate data structure to represent each state during the search
(Node).
b. Define a data structure to represent the queue containing unexplored nodes
(fringe).
c. Write the java function to explore the state space.
2. Problem tests and evaluation
Consider the Farmer Puzzle problem; in this puzzle a Farmer, Wolf, Goat and Cabbage
arrive at a river and wish to cross. There is a boat but it can transport the farmer (only
he can row!) and at most one other object at a time. How can the farmer plan to move
his entourage from the East bank to the West bank? An additional problem is that if ever
the wolf and goat, or goat and cabbage, are left alone then one eats the other!
There are four actions in this puzzle:
Farmer goes alone (ga)
Farmer takes wolf (tw)
Farmer takes goat (tg)
Farmer takes cabbage (tc).
a. We must represent each state of the puzzle; i.e. which side of the river each of the
Farmer, Wolf, Goat and Cabbage is on. Suppose we use a 4 element list [F, W, G, C]
to represent the state and use the constants e and w to represent the east and west
banks respectively.
i. What state is represented by the list [e, e, w, w]?
ii. What are the start and goal states of the puzzle?
iii. What are the unsafe states?
iv. Draw the state space (hint: the unsafe states are not represented in
the state space).
v. Assume that the cost of each action is 1, suggest an admissible
heuristic h.
b. Solve the farmer puzzle problem using your code: display the expanded nodes, the
path solution and its cost (GUI displaying these results is appreciable).
c. Test your program on the 8-puzle problem (the initial and goal states are randomly
generated).
d. Analyze and compare your results on different heuristics (Manhattan distance,
misplaced tiles, and Gashing heuristic).
NB: The assessment of the project is based on:
The provided report describing and discussing the implementation and different
used heuristics and analyzing the obtained results.
The demonstration showing your code and its execution on some problem tests.
Hi there!
I'm a Professional Software developer and Data Analyst for a well known Software House in Islamabad named PacSquare Pvt Ltd. If I get this job, I assure you that you'll get my best services in return. Please consider my proposal, and discuss additional Info for this specific Project. Thanks for Reading!
Best,
Maher
p.s. Will be happy to help, understood the requirements already
Hi i am a software engineer with java and python as expertise. I have been working on java for last 3 years. I have sound knowledge of OOP and procedural programming paradigms.I also have goo understanding of various java apis like swing, jdbc, rpc etc. I also have worked with java soup and have good knoweledg of java crawlers.
I have good communication skills and problem solving strategies. If you give me an opportunity to do this job for you, you will find me with in time and budget. Looking forward for your response
Thanks
Best Regards
Alot of experience in Java programming
Great capabilities in designing applications.
I will be happy to be your assesment, with a decent fee.
Sounds like an interesting project, will be more than glad to be involved.
Ready to work :)
