Suppose that the first goal in a GP problem is to make 3 X1 + 4 X2 approximately equal to 36. Using the deviational variables d1− and d1+, the following constraint can be used to express this goal.
3 X1 + 4 X2 + d1− − d1+ = 36
If we obtain a solution where X1 = 6 and X2 = 2, what values do the deviational variables assume?
a. d1− = 0, d1+ = 10
b. d1− = 6, d1+ = 0
c. d1− = 5, d1+ = 5
d. d1− = 10, d1+ = 0
Answer:
d. d1− = 10, d1+ = 0
Explanation:
Given
3X1 + 4X2 +d1− − d1+ = 36
X1 = 6
X2 = 2
Required
Possible values of d1- and d1+
We have:
3X1 + 4X2 +d1− − d1+ = 36
Substitute values for X1 and X2
3 *6 + 4 * 2 + d1- - d1+ = 36
18 + 8 + d1- - d1+ = 36
Collect like terms
d1- - d1+ = 36 - 18 - 8
d1- - d1+ = 10
For the above equation to be true, the following inequality must be true
d1- > d1+
Hence,
(d) is correct
Because:
10 > 0
Reverse Word Order: Write a program that reverses the order of the words in a given sentence. This program requires reversing the order of the words wherein the first and last words are swapped, followed by swapping the second word with the second to last word, followed by swapping the third word and the third to last words, and so on. Your program will ask the user for an input string and print out the resultant string where the order of the words is reversed. Please see the hints section for more details on an example algorithm. Assume a maximum C-string size of 1000 characters. Make sure your code works for any input number, not just the test cases. Your code will be tested on other test cases not listed here. Do Not Use Predefined Functions from the cstring Library. Please properly comment your code before submission.For this part of the assignment, name your source file as Reverse Word Order_WSUID.cpp. For example, if your user ID is A999B999 name your file as Reverse Word Order_A999B999.cpp. Sample Test Cases: Test Case 1: Input: London bridge has been abducted Output: abducted been has bridge London Test Case 2: Input: Hello World Output: World Hello Test Case 3: Input: Hello World, how are you? Output: you? Are how World, HelloTest Case 4: Input: I like toast Output: toast like l
Answer:
The program in C++ is as follows:
#include <bits/stdc++.h>
using namespace std;
int main(){
string sentence,word="";
getline (cin, sentence);
vector<string> for_reverse;
for (int i = 0; i < sentence.length(); i++){
if (sentence[i] == ' ') {
for_reverse.push_back(word);
word = ""; }
else{ word += sentence[i];} }
for_reverse.push_back(word);
sentence="";
for (int i = for_reverse.size() - 1; i > 0; i--){
sentence+=for_reverse[i]+" ";}
sentence+=for_reverse[0];
cout<<sentence<<endl;
return 0;
}
Explanation:
This declares sentence and word as strings; word is then initialized to an empty string
string sentence,word="";
This gets input for sentence
getline (cin, sentence);
This creates a string vector to reverse the input sentence
vector<string> for_reverse;
This iterates through the sentence
for (int i = 0; i < sentence.length(); i++){
This pushes each word of the sentence to the vector when space is encountered
if (sentence[i] == ' ') {
for_reverse.push_back(word);
Initialize word to empty string
word = ""; }
If the encountered character is not a blank space, the character is added to the current word
else{ word += sentence[i];} }
This pushes the last word to the vector
for_reverse.push_back(word);
This initializes sentence to an empty string
sentence="";
This iterates through the vector
for (int i = for_reverse.size() - 1; i > 0; i--){
This generates the reversed sentence
sentence+=for_reverse[i]+" ";}
This adds the first word to the end of the sentence
sentence+=for_reverse[0];
Print the sentence
cout<<sentence<<endl;
The following program generates an error. Why? #include #include using namespace std; class Arcade { public: Arcade(); Arcade(string name, int r); void Print(); private: string arcName; int rating; }; Arcade:: Arcade() { arcName = "New"; rating = 1; } Arcade:: Arcade(string name, int r) { arcName = name; rating = r; } void Arcade:: Print() { cout << "Name is: " << arcName << endl; cout << "Rating is: " << rating << " stars" << endl; } int main() { Arcade myArc(Games Ablaze, 5); myArc.Print(); }
Answer:
The object creation should be Arcade myArc("Games Ablaze",5);
Explanation:
Required
Why does the program generate an error?
The class definition is correctly defined and implemented;
The methods in the class are also correctly defined and implemented.
The error in the program is from the main method i.e.
int main() {
Arcade myArc('ames Ablaze, 5);
myArc.Print();
}
In the class definition;
Variable name was declared as string and variable rating was declared as integer
This means that, a string variable or value must be passed to name and an integer value or variable to rating.
Having said that:
Arcade myArc(Games Ablaze, 5); passes Games Ablaze as a variable to th function.
Game Ablaze is an incorrect string declaration in C++ because of the space in between Game and Ablaze
Also, no value has been assigned to the variable (assume the variable definition is correct).
This will definitely raise an error.
To correct the error, rewrite the object creation as:
Arcade myArc("Games Ablaze",5); where "Game Ablaze" is passed as string
In this lab, you complete a prewritten C++ program that computes the largest and smallest of three integer values. Instructions Two variables named largest and smallest are declared for you. Use these variables to store the largest and smallest of the three integer values. You must decide what other variables you will need and initialize them if appropriate. Your program should prompt the user to enter 3 integers. Write the rest of the program using assignment statements, if statements, or if else statements as appropriate. There are comments in the code that tell you where you should write your statements. The output statements are written for you. Execute the program by clicking the Run button at the bottom of the screen. Using the input of -50, 53, 78, your output should be: The largest value is 78 The smallest value is -50
Answer:
The program in C++ is as follows
#include <iostream>
using namespace std;
int main(){
int n1, n2, n3, largest, smallest;
cin>>n1>>n2>>n3;
if(n1 >= n2 && n1>=n3){ largest = n1; }
else if(n2 >= n1 && n2>=n3){ largest = n2; }
else{ largest = n3; }
if(n1 <= n2 && n1<=n3){ smallest = n1; }
else if(n2 <= n1 && n2<=n3){ smallest = n2; }
else{ largest = n3; }
cout<<"Smallest: "<<smallest<<endl;
cout<<"Largest: "<<largest<<endl;
return 0;
}
Explanation:
Declare all variables
int n1, n2, n3, largest, smallest;
Get input for the three numbers
cin>>n1>>n2>>n3;
Check if n1 is the largest
if(n1 >= n2 && n1>=n3){ largest = n1; }
Check if n2 is the largest
else if(n2 >= n1 && n2>=n3){ largest = n2; }
Otherwise, n3 is the largest
else{ largest = n3; }
Check if n1 is the smallest
if(n1 <= n2 && n1<=n3){ smallest = n1; }
Check if n2 is the smallest
else if(n2 <= n1 && n2<=n3){ smallest = n2; }
Otherwise, n3 is the smallest
else{ largest = n3; }
Print the smallest
cout<<"Smallest: "<<smallest<<endl;
Print the largest
cout<<"Largest: "<<largest<<endl;

(i) Deadlock
(ii) File manager
(iii) Process
(iv) Multiprogramming
(v) Software Classification
(vi) Virtual memory
Answer and Explanation:
Deadlock occurs when two operating systems on the same computer are hindering each other's execution, getting blocked, waiting for each one to run first. This can happen when a preemption has not occurred, when a mutual exclusion has occurred, or when one of the systems causes the other to not execute.
File manager is software that allows a computer user to create directories and organize files inside and outside of them.
Process is the term used to determine the functioning of computer software. When a software is started, it uses its own programming code to perform a specific activity.
Multiprogramming is the term used for the moment when an operating system allows the user to run more than one software at the same time. For this to happen, the computer needs to have a high processing capacity, to handle the effort of running several software simultaneously.
Software Classification is the process that determines the composition and different aspects that make up a software. In this way, it is possible to understand the usefulness and programming of this software.
Virtual memory is the use of secondary memory for caching. This allows the user to share files more securely and quickly, in addition to alleviating the problems that limited memory presents.
A computer never gets tired or bored while working for a long time _______
Answer:
Diligence
Explanation:
The computer possess several qualities including tbe ability to be consistent with its task and accuracy of its output. When describing a person or machine that delivers so much over a long periodof time without being weary, bored or tired, such person or machine could be described as being Diligent. Depending on the task a computer is being used to execute, computer machines are usually being used in a non-stop manner. For instance, firms that works on shift basis may have 3 to 4 working shifts per day with each shift making use of the same computer used by the previous shift everyday for several number of days. Example are telecommunications customer service firms who work on a 24 hours basis.

The input to the function/method consists of two arguments.
a. True
b. False
Answer:
See Explanation
Explanation:
The function is not given. So, I will provide general explanation.
A function is defined as:
return-type function-name(argument-lists)
For instance, an int function that has 1 argument is:
int Myfunc(int num)
num is the argument of the function Myfunc
So, an example of a function with two arguments is:
int Myfunc(int num, string name)
So, examine the function in the complete question; then count the number of arguments to determine if the answer is true or false.

Design traffic lights at an intersection of a city. North and South (up and down) are going to be a main highway, East and West (right and left) will be a smaller cross street. There will be no turn signals and no cross walks. You only need to build/code one set of lights for each street (one set of green, yellow, and red for the highway, and another set for the cross street). You do not need to build actual traffic lights or an intersection.
Answer:
Explanation:
The following code is written in Java. In order to code this efficiently, I created a class for the trafficLights. The class contains the currentLight, and the streetType as variables and contains a constructore, getter and setter methods, and a method to turn to the next light in the sequence. Then I created 4 objects of TrafficLights for the highways and the streets.
class Brainly {
public static void main(String[] args) {
TrafficLights highwaySouth = new TrafficLights("Highway", "green");
TrafficLights highwayNorth = new TrafficLights("Highway", "green");
TrafficLights streetEast = new TrafficLights("Street", "yellow");
TrafficLights streetWest = new TrafficLights("Street", "red");
}
}
class TrafficLights {
String streetType, currentLight;
public TrafficLights(String streetType, String currentLight) {
this.streetType = streetType;
this.currentLight = currentLight;
}
public void nextLight() {
if (this.currentLight == "green") {
this.currentLight = "yellow";
} else if (this.currentLight == "yellow") {
this.currentLight = "red";
} else {
this.currentLight = "green";
}
}
public String getStreetType() {
return streetType;
}
public void setStreetType(String streetType) {
this.streetType = streetType;
}
public String getCurrentLight() {
return currentLight;
}
public void setCurrentLight(String currentLight) {
this.currentLight = currentLight;
}
}

what's the difference between pseudo code and natural language
Answer:
The pseudo-code describes steps in an algorithm or another system in plain language. Pseudo-Code is often designed for human reading rather than machine reading with structural conventions of a normal language of programming.
Natural languages consist of phrases, usually declarative phrases, with a sequence of information.
Explanation:
Pseudo-Code is often designed for human reading rather than machine reading with structural conventions of a normal language of programming. It usually omits information that is essential to the understanding of the algorithm by the machine, for example, variable declarations and language code.Easily human, but not machines, use the natural languages (like English).Natural languages also are creative. Poetry, metaphor, and other interpretations are permitted. Programming permits certain style differences, but the significance is not flexible.The aim of using pseudo-code is to make it easier for people to comprehensibly than standard programming language code and to describe the key principles of an algorithm efficiently and environmentally independently. It is usually used for documenting software and other algorithms in textbooks and scientific publications.Think about that the C, B and S parameters of a Cache.

In a paragraph, describe in detail a practical real-world example of where you would implement a singly-linked list and why a singly-linked list is best for this use. Do not list the properties of a singly-linked list....
Rather identify a real-world example or application. If you identify this through research, cite your source.
Answer:
travel
Explanation:
One real world example of a singly-linked list would be travel. Imagine that you want to take a trip to your nearest neighbor state. To do so you would need to take a 2 buses and a train, but you can't just take any or in any order you wish. You first need to take the first bus at your current location, get off at the train station, take that train to the final stop, get off and take the bus to the final destination. Meaning there is a sequence of connected events that you must follow in order to get to your destination and the same opposite sequence of events to get back. This is exactly like a singly-linked list.

Determine whether or not the following pairs of predicates are unifiable. If they are, give the most-general unifier and show the result of applying the substitution to each predicate. If they are not unifiable, indicate why. Assume that x, y, and z are variables, while other symbols are either predicates, constants, or functions.
a) P(B,A,B), P(x,y,z)
b) P(x,x), Q(A,A)
c) Older(Father(y),y), Older(Father(x),John).
d) Q(G(y,z),G(z,y)), Q(G(x,x),G(A,B)
e) P(f(x), x, g(x)), P(f(y), A, z)
Answer:
a) P(B,A,B), P(x,y,z)
=> P(B,A,B) , P(B,A,B}
Hence, most general unifier = {x/B , y/A , z/B }.
b. P(x,x), Q(A,A)
No mgu exists for this expression as any substitution will not make P(x,x), Q(A, A) equal as one function is of P and the other is of Q.
c. Older(Father(y),y), Older(Father(x),John)
Thus , mgu ={ y/x , x/John }.
d) Q(G(y,z),G(z,y)), Q(G(x,x),G(A,B))
=> Q(G(x,x),G(x,x)), Q(G(x,x),G(A,B))
This is not unifiable as x cannot be bound for both A and B.
e) P(f(x), x, g(x)), P(f(y), A, z)
=> P(f(A), A, g(A)), P(f(A), A, g(A))
Thus , mgu = {x/y, z/y , y/A }.
Explanation:
Unification: Any substitution that makes two expressions equal is called a unifier.
a) P(B,A,B), P(x,y,z)
Use { x/B}
=> P(B,A,B) , P(B,y,z)
Now use {y/A}
=> P(B,A,B) , P(B,A,z)
Now, use {z/B}
=> P(B,A,B) , P(B,A,B}
Hence, most general unifier = {x/B , y/A , z/B }
b. P(x,x), Q(A,A)
No mgu exists for this expression as any substitution will not make P(x,x), Q(A, A) equal as one function is of P and the other is of Q
c. Older(Father(y),y), Older(Father(x),John)
Use {y/x}
=> Older(Father(x),x), Older(Father(x),John)
Now use { x/John }
=> Older(Father(John), John), Older(Father(John), John)
Thus , mgu ={ y/x , x/John }
d) Q(G(y,z),G(z,y)), Q(G(x,x),G(A,B))
Use { y/x }
=> Q(G(x,z),G(z,x)), Q(G(x,x),G(A,B))
Use {z/x}
=> Q(G(x,x),G(x,x)), Q(G(x,x),G(A,B))
This is not unifiable as x cannot be bound for both A and B
e) P(f(x), x, g(x)), P(f(y), A, z)
Use {x/y}
=> P(f(y), y, g(y)), P(f(y), A, z)
Now use {z/g(y)}
P(f(y), y, g(y)), P(f(y), A, g(y))
Now use {y/A}
=> P(f(A), A, g(A)), P(f(A), A, g(A))
Thus , mgu = {x/y, z/y , y/A }.
