Current U.S. military doctrine recognizes four categories of power available to a nation: diplomatic, informational, military, and economic. Upon examination, it is apparent that only a nation/state can wield these elements of power; they would be beyond the reach of weaker powers or organizations. How then, can these lesser entities influence the powerful? Five “underdog” strategies are outlined as alternative sources of power for the weak. If you are trying to influence the national policy of the United States, which of these five strategies do you feel would be the most effective? Why?

Linux Question: you will practice on creating and editing a text file by VI.

How to:

1. Install JDK 1.8 by the following command:

$ sudo yum    –y    install    java-1.8.0-openjdk-devel.x86_64

2. Use VI to create a file “YourFirstNameHomework.java” (e.g., “MollyHomework.java”) and add the following contents into it. (grading details: file name format:10 pts, a screenshot of the file content in the VI environment: 10pts, paragraphs: 10pts, empty lines and indentations: 10, text: 10pts)

Here's the code

3.To compile the above java code, run the following command (you need to use your java file name):

$ javac MollyHomework.java

4. To execute the java program, run the following command

$ java MollyHomework

Question:

Describe how you created above file and its contents in VI.

1. Bash/VI commands: 20pts;
2. Non-brute-force solution: 10pts).

Note: Brute-force solution means that entering characters one by one.

Write a C++ program that will be an information system for Oregon State University using classes as well as demonstrating a basic understanding of inheritance and polymorphism.

You will create a representation of an Oregon State University information system that will contain information about the university. The university will contain a name of the university, n number of buildings, and m number of people. People can be either a student or an instructor. Every person will have a name and an age. Every student will have also have a GPA, but an instructor will NOT have a GPA. Every instructor will have an instructor rating, but a student will NOT have an instructor rating. Every building will have a name, the size in sqft (preferred the real value which you need to look up), and an address (stored as a string, also preferred to look this up).

People will contain a method called “do_work” that will take in a random integer as a parameter that represents how many hours they will do work for. If the person is a student, a message will be printed to the screen that says “PERSON_NAME did X hours of homework.” If the person is an instructor, a message will be printed to the screen that says “Instructor PERSON_NAME graded papers for X hours.” You will need to fill in the appropriate values.

The student GPA can either be an input from the user or randomized, but it must be between 0.0 and 4.0. It cannot be preset. The instructor rating can either be an input from the user or randomized, but it must be between 0.0 and 5.0. The ages of a person can be randomized or an input, but make it realistic. You can choose whether it is randomized or user input, or both.

The university will contain a method that will print the name and address of all the buildings in its information system and another method that will print the name of all the people. The name of the university MUST be “Oregon State University” (because we are the best).

You will manually instantiate at least 1 student, 1 instructor, and 2 buildings, then give them values and store them appropriately in the university object. You can do this in whatever fashion you wish.

You will have a menu that does at least the following:

1) Prints names of all the buildings

2) Prints names of everybody at the university

3) Choose a person to do work

4) Exit the program

Note that option 3 will require you to print another menu that gives options for each person.

You may create any other functions, methods, member variables, etc. to modularize your code and complete the lab.

Extra Credit Add an option to save the information system to a file, and add an option to read a saved information system from a file so that you can close the program, but not lose information. This will also require you to be able to add people and/or buildings to the program during runtime. This is an all or nothing extra credit (you will not get partial points for partial completion).

Class GroceryBag
collects instances of class Item in an appropriate data structure.

                      Class Item
                ---------------------------
               -String description
               -int cost   //price in cents
               ----------------------------
               + [constructor, getters, and a toString() method]
•         (Assume class Item has already been coded)

                      Class GroceryBag (Highlights)
               ----------------------------------
                 -bag   // an ArrayList of <Item>
               ----------------------------------
                  assume public methods: constructor, totalBag(), findItem(String it), listAll(), etc.

•         The ONLY thing you need to do in the space below is to write java code for the complete method specified:
•         In the space below, write code for a complete method
                                  void showCheapItems()
that will use the ArrayList bag and which will display all Items in the bag whose price is below the overall average of
all the prices of all the items in the bag.
[Hint: average will be the sum divided by the number of items].
Required: use at least one for-each loop as part of your method.

Consider the following Java program. Describe what it does in response to specific operations of the mouse, and how it does it. (You are encouraged to run the program for yourself to test its behavior. Then read through the program carefully to understand how that behavior arises.)

import javax.swing.*;
public class MouseWhisperer extends JFrame implements MouseListener {
    MouseWhisperer() {
        super("COME CLOSER");
        setSize(300,100);

        addMouseListener(this);
        setVisible(true);
    }

    public static void main(String[] args) { new MouseWhisperer(); }

Implement the Metropolis-Hastings algorithm below¶

Make sure to read this: Implement the algorithm described above (in the "How it works" section), where you take some user-defined number of steps that randomly step in W and I and are scaled by a step_size. This means you don't want to take steps of a discrete size, but instead use a random distribution of step sizes that are scaled by your step_size variable. You'll want to take steps that have an equal chance of either decrementing or incrementing the values of W and I. Also, W and I don't have to incremented by the exact same amount, in fact, it would best if they weren't so that you can explore more of the parameter space.

Keep track of your accepted guesses for width and intercepts in the lists that are provided below. We have included variables with reasonable values of these quantities to get you started.

# Total number of points we're going to sample (start out with at least 10^4)
num_sample_points = 100000

# Weight factor in front of the random step
step_size = 0.1

# As we move the walker around, we'll use these same lists to
# store our new values so that we can visualize the path later!

# (Note: that means you'll want to append new values to these lists!)

widths = [2]
intercepts = [2]
