Hi.. I am a newbie in this forum. I am the student of computer science. I need to find the algorithms for the shortest path finding. And i need to know the comparison of them.. Thank you so much. Nice to meet you.. :)

You are asking us to write a review of existing algorithms for you. A forum is not the right place to find this: There is plenty of material on the web about it. Or you could pick up a book from your school's library.
