I am trying to build a solution where i would create loop by google map. My first and only business rule is there should not be any repeated route. But with my demo it does show.

Please help me on this .

Perhaps you could tell us a little bit more about what this app is trying to do? My guess is that after you specify a location and a distance, it tries to find a closed circuit of the desired distance originating at that point and your concern is that the existing algorithm performs a lot of backtracking. However, these are purely guesses and could be mistaken. – whuber Mar 2 '12 at 14:53
You are right it does perform lot of backtracks and i would like to get rid of it. – user1089553 Mar 5 '12 at 6:55
I got the solution its about taking 45 degree angle and then work around – user1089553 Mar 22 '12 at 9:36
@mehulNahar That's great! Can you post it as an answer and accept it so that other users may learn from it? – R.K. Dec 21 '12 at 4:58
How can I accept my own solution ? – user1089553 Dec 21 '12 at 12:20
