A polygon is a two-dimensional closed shape defined by connections between points or vertices.A triangulation of a polygon can be thought of as a set of chords that divide the polygon into triangles such that no two chords intersect (except possibly at a vertex). It can be formed by drawing diagonals between non-adjacent vertices such that the diagonals never intersect. The cost of a triangulation is sum of the weights of its component triangles. Weight of each triangle is its perimeter (sum of lengths of all sides). An optimal triangulation is one that minimizes some cost function of the triangles. The idea is to divide the polygon into three parts: a single triangle, the sub-polygon to the left, and the sub-polygon to the right. Try all possible divisions like this until you find the one that minimizes the cost of the triangle plus the cost of the triangulation of the two sub-polygons. You can get the cost of triangulation of the two sub-polygons recursively. The base case of the recursion is a line segment (i.e., a polygon with zero area), which has cost 0.In this project, you have to design a suitable algorithm implementing the Optimal Polygon Triangulation. Show the triangulations along with the minimal cost. You should use Dynamic Programming in this regard. Avoid using Brute Force as it may take exponential time, while dynamic programming is much faster in comparison.
