Optimization is the problem of finding the best feasible solution to the problem. Optimization in healthcare is in the industry from past three decades. But now-a-days optimizations in healthcare have become noticeably and is attracting operation researchers because of the decreasing birth rates in nearly all the developed countries. Optimization has been applied in healthcare for various problems from operational level decisions to the designing of national healthcare policies. This case study

shortest possible route that visits each city exactly once and returns to the origin city? It is an NP-hard problem in combinatorial optimization‚ important in operations research and theoretical computer science. The problem was first formulated in 1930 and is one of the most intensively studied problems in optimization. It is used as a benchmark for many optimization methods. Even though the problem is computationally difficult‚[1] a large number of heuristics and exact methods are known‚ so that
