Here are some possible ideas you can focus on developing the problem statement-
1. What are the environmental & health issues majorly impacting dumpsite people?
2. Are there adequate studies on spreading awareness on the issues or recommendations to address the issues?
3. If yes, what are the methods used and recommended by these studies? Are they helpful in mitigating the problem? Where are they lacking and how your study will contribute in tackling the gap?
4. If no, how your study will make a difference in the situation?
The Christofides algorithm follows a similar outline but combines the minimum spanning tree with a solution of another problem, minimum-weight perfect matching . This gives a TSP tour which is at most times the optimal. The Christofides algorithm was one of the first approximation algorithms , and was in part responsible for drawing attention to approximation algorithms as a practical approach to intractable problems. As a matter of fact, the term "algorithm" was not commonly extended to approximation algorithms until later; the Christofides algorithm was initially referred to as the Christofides heuristic.
