Given a group of boxes, you are requested to arrange these boxes on top of each other to reach the maximum possible height. Note: a box cannot be placed on top of another box unless the area of its 2D base is smaller or equal of the 2D base of the lower box. It is allowed to rotated any box to use any two sides as its base.

For example, consider below 4 boxes where each box has the following dimensions

Input:

Box 1: (4,5,2), Box 2:(3,1,6), Box 3:(3,2,1),

Box 4:(6,8,3)

Output:

From bottom to top as follows:

Box 4 on the base (6,3) and height 8,

then Box 1 on the base (4,2) and height 5, then Box 2 on the base (1,3) and height 6, finally, on top Box 3 on the base (2,1) and height 3.

The total height is 22

[Explanation: as we can see that the first box in the bottom is the box # 4 with base 6x3 and height 8, then box # 1 with base 4x2 and height 5, and so on. This arrangement of boxes fulfils the constraint mentioned above: “the dimensions of the 2D base of the lower box are each strictly larger than those of the 2D base of the higher box”. This solution also satisfies the tallest possible stack]

1. Describe how a brute-force approach algorithm would solve the above problem , and explain its complexity .
2. Design an algorithm to solve the above scenario for N boxes.[full explanation of your answer should be provided]
3. What will happen to the complexity of your efficient algorithm if the constraint “a box cannot be placed on top of another box unless the area of its 2D base is smaller or equal of the 2D base of the lower box” is not required anymore?
4. Develop a python code to implement your efficient algorithm.

Please DO NOT respond to this question by copy/pasting the code provided elsewhere on the site, none of those work. Thanks. Virtual Memory Lab This lab project addresses the implementation of page-replacement algorithms in a demand-paging system. Each process in a demand-paging system has a page table that contains a list of entries. For each logical page of the process, there is an entry in the table that indicates if the page is in memory. If the page is in memory, the memory frame number that page is resident in is indicated. Also, for each page, the time at which the page has arrived in memory, the time at which it has been last referenced, and the number of times the page has been referenced since the page arrived in memory are maintained. The page table data structure is a simple array of page-table entries (PTEs). Each PTE contains five fields as defined below: struct PTE { int is_valid; int frame_number; int arrival_timestamp; int last_access_timestamp; int reference_count; } Each process in the system has a page table that is simply an array of PTEs. Each process also has a pool of frames that is allocated. The frame pool for a process is represented as an array of integers, where each Integer represents the frame number of a frame that is free and is available for use by the process. Note that in order to get the frame number in the pool, you first need to access the integer in the array. This lab project aims to exercise the various policies for page replacement. In particular, we study the following three page-replacement policies: First-In-First-Out (FIFO) Least-Recently-Used (LRU) Least-Frequently-Used (LFU) In order to implement the above policies, we need to develop corresponding functions that process page accesses for a process. That is, for each process, given its page table, a logical page number being referenced and the free frame pool of the process, the functions should determine the memory frame number for the logical page. Also, the functions should modify the page table and the free frame pool appropriately. The details of the functions with respect to the different policies are described below. You need to develop code for these functions that implement the specifications. Place the code in a file called virtual.c. You should include the oslabs.h file.

Globalization has created many opportunities for organizations. There are many advantages and ways to create value through outsourcing portions of one's global supply chain. For each opportunity, there are also many ways for the project to run into problems. In your initial post, address the following: Identify one example of an organization that created value for itself through outsourcing part of its supply chain. Provide a link to one resource. Identify the benefit that occurred. How did this benefit help the organization create value? Who was the value created for—the organization, or the customer? In your replies to at least two peers, discuss potential risks of outsourcing for the examples they provided—for example, risks to supplier quality or stability, intellectual property, or reputation. The following questions may help develop your responses: Can you provide an example of an organization that started outsourcing the supply chain and then stopped? What risks did the organization face that caused them to stop the project? Can you provide an example of an organization that outsourced similarly and faced reputational damage due to the project?
