In terms of most popular algorithms we try to make each case efficient by applying a satisfied algorithm. Those are not codes. those are mainframe for a problem. In terms of Algorithms with multiple answer for a single problem. it's only a time to understand the paradoxical reality. To briefly explain my words, if I want to travel to Shitakunda, there are 19 possible way from Dhaka. each contain different transportation system. If I choose one that is cheapest along with fastest, I'm just choosing one reality. Can we rise upon this topic to make a suitable AI based solution. A solution that can change for anytime. a solution that can measure like a human mind?  Well both comes with a single portion and that's actually "Problem Solving ".
