” 辅导COMP557语言程序、写作R程序COMP331/COMP557 OptimisationProgramming AssignmentDue date: Thursday, December 10th, 2020, noon, via SAM( httpss://sam.csc.liv.ac.uk/COMP/Submissions.pl?strModule=COMP331 or httpss://sam.csc.liv.ac.uk/COMP/Submissions.pl?strModule=COMP557)This assignment is worth 10% of your grade.We are given a triangular array of 36 nodes in the plane that are connected among each other as follows.A small triangle is a set of three adjacent nodes. If two small triangles share two nodes, then they form a smallrhombus. In each Small rhombus, two nodes are at obtuse corners and two nodes are at acute corners:Each of the 36 nodes gets Assigned a height, which is a real number. Hence,by linear interpolation between the nodes, a height vector h R36 gives riseto a triangulation of a surface in 3-dimensional space that on a small rhombuslooks as the picture on the right.We will only consider those height vectors that have fixed heights as follows on the nodes at the boundary:Figure 1A height vector h R36 is called mountain if for all Small rhombi (in all three rotations) we have that the sumof the heights of the nodes at the obtuse corners is at least as high as the sum of the nodes at the acute corners.1/2COMP331/COMP557 OptimisationHere is an example of a mountain:The inequalities for all small rhombi are satisfied, for example 6+4 10+0 and 10+4 6+7 and 10+6 12+4.A weighting w R36 is a vector of Real numbers. For a given weighting w, the w-weight weightw(h) of amountain h is defined asweightw(h) = Xnode vw(v) h(v).For a given weighting w, a mountain h is called w-optimal if there is no other mountain with a higher w-weight.The set of mountains whose Heights at the boundary nodes are as illustrated in Figure 1 forms a polytopein R15. Your taks is to experimentally Determine the number of the polytopes vertices. This shall be done bychoosing random linear objective functions and maximising them within the polytope.1. Write a function (in any programming language) that picks a random weighting w and writes to the diskan .lp file Whose optimal solution is a w-optimal mountain.2. Write a program that calls the above function 1000 times to generate 1000 .lp files, calls glpsol on thosefiles and analyses the output. After this analysis, the program should output the set of distinct mountainsthat were found.3. For each Mountain that was found, draw a picture analogous to Figure 2. Put them in a single .pdf file.Submission format: Put the following into a single .zip file:1. The program code.2. The 1000 .lp files.3. The .pdf file containing the figures of the mountains analogous to Figure 2.如有需要，请加QQ：99515681 或邮箱：99515681@qq.com
