Idea of maximum parsimony in phylogenetic tree construction

Question

Write down the main idea of maximum parsimony in the phylogenetic tree construction. And also write down the demerits?

Answer 1

Maximum Parsimony (or MP) problem aims at the reconstructing the phylogenetic tree from DNA series while minimizing the number of the genetic transformations. To resolve this NP- complete problem, heuristic techniques have been developed, frequently based upon local search. In this paper, we focus on affect of the neighborhood relations.
