From the list of problems below, check all that are known to be NP-complete. You do not need to justify your answer. (Set cover)

White raven [17]

Any computing issue that falls within the category of NP-complete problem has yet to find an effective solution algorithm.

<h3>Which problems are NP-complete?</h3>

Any of a family of computer problems that have no effective solution algorithm are referred to as NP-complete issues.
The traveling salesman problem, satisfiability issues, and graph-covering issues are only a few examples of the significant computer science issues that fall under this category.
The difficulty of NP and NP-Complete issues is equal. If a problem is included in both NP and NP-Hard Problems, it is said to be NP-Complete.
This statement, "This problem can change into an NP-complete problem on a non-deterministic Turing machine," is untrue for the obvious reason that while any problem in P is also a problem in NP, no problem in P is an NP-complete problem (unless P=NP, of course). If P is an NP problem and all NP problems convert into NP-complete problems, then P must also undergo this transformation.

Create an abstract class DiscountPolicy. It should have a single abstract method computeDiscount that will return the discount f

eimsori [14]

Answer:

Java Code was used to define classes in the abstract discount policy,The bulk discount, The buy items get one free and the combined discount

Explanation:

Solution

Code:

Main.java

public class Main {

public static void main(String[] args) {

BulkDiscount bd=new BulkDiscount(10,5);

BuyNItemsGetOneFree bnd=new BuyNItemsGetOneFree(5);

CombinedDiscount cd=new CombinedDiscount(bd,bnd);

System.out.println("Bulk Discount :"+bd.computeDiscount(20, 20));

System.out.println("Nth item discount :"+bnd.computeDiscount(20, 20));

System.out.println("Combined discount :"+cd.computeDiscount(20, 20));

}

}

discountPolicy.java

public abstract class DiscountPolicy

{

public abstract double computeDiscount(int count, double itemCost);

}

BulkDiscount.java

public class BulkDiscount extends DiscountPolicy

{

private double percent;

private double minimum;

public BulkDiscount(int minimum, double percent)

{

this.minimum = minimum;

this.percent = percent;

}

at Override

public double computeDiscount(int count, double itemCost)

{

if (count >= minimum)

{

return (percent/100)*(count*itemCost); //discount is total price * percentage discount

}

return 0;

}

}

BuyNItemsGetOneFree.java

public class BuyNItemsGetOneFree extends DiscountPolicy

{

private int itemNumberForFree;

public BuyNItemsGetOneFree(int n)

{

itemNumberForFree = n;

}

at Override

public double computeDiscount(int count, double itemCost)

{

if(count > itemNumberForFree)

return (count/itemNumberForFree)*itemCost;

else

return 0;

}

}

CombinedDiscount.java

public class CombinedDiscount extends DiscountPolicy

{

private DiscountPolicy first, second;

public CombinedDiscount(DiscountPolicy firstDiscount, DiscountPolicy secondDiscount)

{

first = firstDiscount;

second = secondDiscount;

}

at Override

public double computeDiscount(int count, double itemCost)

{

double firstDiscount=first.computeDiscount(count, itemCost);

double secondDiscount=second.computeDiscount(count, itemCost);

if(firstDiscount>secondDiscount){

return firstDiscount;

}else{

return secondDiscount;

}

}

The air contained in a room loses heat to the surroundings at a rate of 60 kJ/min while work is supplied to the room by computer

charle [14.2K]

Answer:

The net amount of energy change of the air in the room during a 10-min period is 120 KJ.

Explanation:

Given that

Heat loss from room (Q)= 60 KJ/min

Work supplied to the room(W) = 1.2 KW = 1.2 KJ/s

We know that 1 W = 1 J/s

Sign convention for heat and work:

1. If heat is added to the system then it is taken as positive and if heat is rejected from the system then it is taken as negative.

2. If work is done by the system then it is taken as positive and if work is done on the system then it is taken as negative.

So

Q = -60 KJ/min

In 10 min Q = -600 KJ

W = -1.2 KJ/s

We know that

1 min = 60 s

10 min = 600 s

So W = -1.2 x 600 KJ

W = -720 KJ

WE know that ,first law of thermodynamics

Q = W + ΔU

-600 = - 720 + ΔU

ΔU = 120 KJ

The net amount of energy change of the air in the room during a 10-min period is 120 KJ.
