For minimization problems, the optimal objective function value to the LP relaxation provides what for the optimal objective function value of the ILP problem?
Answer:
A lower bound on the optimal integer value.
Explanation:
The question is poorly typed. The original question requires the optimal solution of the objective function of a minimization problem
I will answer this question base on the above illustration.
When an objective function is to be minimized, it means that the objective function will take the feasible solution with the least value.
The least value are often referred to as the lower bound.

A python code only runs the except block when _____. Group of answer choices all the statements in the try block are executed an error occurs in the preceding try block the programmer manually calls the except block an error occurs anywhere in the code
Answer:
Python only running exception block when try block fails
Explanation:
i do cyber security and i was learning this in high school
In Python, try and except statements are used to catch and manage exceptions. Statements that can generate exceptions were placed within the try clause, while statements that handle the exception are put within the except clause.
An exception should be caught by except block, which is used to test code for errors that are specified in the "try" block. The content of the "except" block is executed if such a fault/error appears.In Python, the exception block only runs when an error occurs in the try block.Therefore, the answer is "try block fails ".

Explanation:
(Ramanujan's Taxi) Srinivasa Ramanujan indian mathematician who became famous for his intuition for numbers. When the English mathemematician G.H. Hardy came ot visit him in the hospital one day, Hardy remarked that the number if his taxi was 1729, a rather dull number. To which Ramanujan replied, "No, Hardy! It is a very interesting number. It is the smallest number expressible as the sum of two cubes in two different ways." Verify this claim by writing a program Ramanujan.java that takes a command-line argument N and prints out all integers less than or equal to N that can be expressed as the sum of two cubes in two different ways. In other words, find distinct positive integers a, b, c, and d such that а3 + b3 = c3 - d3. Hint: Use four nested for loops, with these bounds on the loop variables: 0 < a < 3√N, a < b < 3√N - a3, a < c < 3√N and c < d < 3√N - C3; do not explicitly compute cube roots, and instead use x . x *x < y in place of х < Math.cbrt (y).

$ java Ramanujan 40000
1729 = 1"3 + 12^3 = 9^3 + 10"3
4104 = 2^3 + 16^3 = 9^3 + 15^3
13832 = 2^3 + 24^3 = 18^3 + 20^3
39312 = 2^3 + 34^3 = 15^3 + 33^3
32832 = 4^3 + 32^3 = 18^3 + 30^3

A company manufactures televisions. The average weight of the televisions is 5 pounds with a standard deviation of 0.1 pound. Assuming that the weights are normally distributed, what is the weight that represents the 75th percentile?
Answer:
5.0674
Explanation:
Given that :
Mean, μ = 5 pounds
Standard deviation, σ = 0.1
Given that weight are normally distributed ;
From the Z table, the Zscore or value for 75th percentile weight is :
P(Z < z) = 0.75
z = 0.674
Using the relation :
Zscore = (x - μ) / σ
x = weight
0.674 = (x - 5) / 0.1
0.674 * 0.1 = x - 5
0.0674 = x - 5
0.0674 + 5 = x - 5 + 5
5.0674 = x
The weight which corresponds to the 75th percentile is 5.0674

Design a class named Employee. The class should keep the following information in member variables:
Employee name
Employee number
Hire Date
Write one or more constructors and the appropriate accessor and mutator functions for the class.
Next, write a class named ProductionWorker that is derived from the Employee class. The ProductionWorker class should have member variables to hold the following information:
Shift (an integer)
Hourly pay rate (a double)
The workday is divided into two shifts: day and night. The shift variable will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write one or more constructors and the appropriate accessor and mutator functions for the class. Demonstrate the classes by writing a program that uses a ProductionWorker object."
Now I have written out the program, it compiles without errors. However, when I run it It asks the first question "Employees name" after input it errors and closes itself down. Can anyone find where in my code it is causing it to do this please? To be clear, I am not asking for someone to write the program, I have already done this, just need to know why it compiles but does not run all the way through. Thank You!

Ten examples of an interpreter
Answer:
Some popular examples of today's interpreters are:
Interpreter of PythonInterpreter for RubyPerl performerInterpreter for PHPMATLAB UCSD PascalExplanation:
An interpreter executes the commands directly in an object code or a machine code, written in a program or a scripting language.
The Interpreter can be referred to as system software that can read and execute the programme instead of interpreting programmes. This interpretation includes high-level source code, pre-compiled programmes and scripts.
It is important to note that the interpreter translates programme by programme line, meaning that one statement is translated on one go. This feature makes it easy for programmers to check any line on debugging but slows the whole programme running time.
Several families are planning a shared car trip on scenic drives in New Hampshire's White Mountains. To minimize the possibility of any quarrels, they want to assign individuals to cars so that no two members of a family are in the same car. Explain how to formulate this problem as a network flow problem.
Answer:
Following are the response to the given question:
Explanation:
Build a spring, sink, vertices, and vertices for each car for a household. Every unit in the stream is a human. Attach the source from each vertical of a family with such a capacity line equivalent to the family size; this sets the number of members in each household. Attach every car vertices to the sink with the edge of the car's passenger belt; this assures the correct number of people for every vehicle. Connecting every vertex in your household to any vertex in your vehicle with a capacity 1 border guarantees that one family member joins a single car. The link between both the acceptable allocation of people to vehicles as well as the maximum flow inside the graph seems clear to notice.

Explain in details:
(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.
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.We will find an video named????

Which of the following CALL instructions writes the contents of EAX to standard output as a signed decimal integer?
a. call WriteInteger
b. call WriteDec
c. call WriteHex
d. call WriteInt
Answer:
d. call WriteInt
Explanation:
Required
Instruction to write to decimal integer
Of the 4 instructions, the call WriteInt instruction is used write to a decimal integer.
This is so, because the WriteInt instruction writes a signed decimal integer to standard output.
This implies that the output will have a sign (positive or negative) and the output will start from a digit other than 0 (i.e. no leading zero)
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?

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;

What intangible benefits might an organization obtain from the development of an
information system?
Answer:
The immaterial benefits stem from the development of an information system and cannot easily be measured in dollars or with confidence. Potential intangible advantages include a competitive need, timely information, improved planning and increased flexibility in organisation.
Explanation:
Intangible advantages
Take faster decisionsCompetitive needMore information timelyNew, better or more information availability.Lower productivity and the lack of 'think outside' employees and managers as well as greater sales include the intangible costs of such an operational environment. All these factors improve when employees spend less of their time in addressing current methods of operation and are concerned about whether they will have a job or an employer in six months or a year. The automation level envisaged in this new system should enhance the overall efficiency of management. The operative controls and design functions should be simplified by tight system integrations with accessible automated database sources. However, it is difficult to describe the exact form of these simplifications.
Tangible costs of the new system include costs of analysis, design and construction of the system, such as the recruitment of contractors or new employees, and the assignment of existing staff. Also consideration shall be given to hardware, software purchased and operating costs. Intangible costs include disturbances to the current activities caused by development and deployment and potential adverse effects on the morals of employees.
While the new system may feel good in the long term, short-term stress and other negative consequences will still be present. In the way that Reliable does virtually everything, the system is the focus of a major change. An organisation's monumental change has widespread negative effects on operations and employees.
