Heuristic System

The term heuristic is derived from the Greek word heurisko, which means “I find, discover”. Heuristics can be mental shortcuts or approaches designed from previous experiences. The main aim of the heuristic approach is to find a good enough solution to solve the problem. Test and mistake, rule of thumb, or an educated estimate are all examples of heuristics. These methods are sufficient for achieving an immediate, brief aim. When a heuristic is used in practice, it works as predicted. It can, however, produce systematic errors. Trial and error is an important heuristic that may be used in a variety of situations, from cross-linking nuts and bolts to determining the values of given input variables in mathematical puzzles. Additional hypotheses, visual illustrations, simplification, and forward or backward reasoning are all common heuristics in mathematics.

Question

2. Get the Groups
As new students begin to arrive at
college, each receives a unique ID
number, 1 to n. Initially, the students do
not know one another, and each has a
different circle of friends. As the
semester progresses, other groups of
friends begin to form randomly.
There will be three arrays, each aligned
by an index. The first array will contain a
queryType which will be either Friend or
Total. The next two arrays, students1
and students2, will each contain a
student ID. If the query type is Friend,
the two students become friends. If the
query type is Total, report the sum of
the sizes of each group of friends for the
two students.

Right now we have a CourseListType that will hold a static 50 courses. Now we need to make that a little more flexible. To do that we want to change the static array to a dynamic array. So, what do we need to do? Modify CourseListType so that it contains a pointer to a CourseType rather than an array of CourseType. Modify the CourseListType constructor to create a dynamic array allocating space for a specific number of CourseType elements rather than always using 50. (Note: This is still not totally flexible, but is much better than a static limit.) Finally, we need to create a destructor to for CourseListType to deallocate space whenever a declared object goes out of scope.) //courseListType.h file #ifndef COURSELISTTYPE_H_INCLUDED#define COURSELISTTYPE_H_INCLUDED #include <string>#include "courseType.h" class courseTypeList { public:void print() const;void addCourse(std::string);courseTypeList(); private:static const int NUM_COURSES = 50;int courseCount;courseType…
Go on https://www.imdb.com/ and look up for some movies. Select at least 10 movies. For each movie you choose, store its title into an array called movies and its rate (score) into a second array called ratings. The same information for a single movie must be stored in elements having the same index in the two arrays. For example, if Jurassic Park is the third movie you choose, then both its title and its rate should have index 2.movies[2] = "Jurassic Park";rating[2] = 8.1;Once you filled your arrays, print the list of all the movies from the highest score to the lowest. Follow this format:number_in_ranking. movie_title (movie_rate) newlineIf two movies have the same rate, their order doesn’t matter.Note: You cannot use structs, you cannot use classes, you cannot use matrices, you cannot use advanced data structures, you cannot use std::swap.Note: You can use templates if you need to.Remember to comment the code such that it is easy for other developers to understand it.Example (with 5…
Determine if the following statement are true or false screen shot shows the text's SortedArrayCollection and ArrayCollection When comparing two objects using the == operator, what is actually compared is the references to the objects. When comparing two objects using the equals method inherited from the Object class, what is actually compared is the references to the objects. The text's sorted array-based collection implementation stores elements in the lowest possible indices of the array. The text's array-based collection implementation stores elements in the lowest possible indices of the array.
Retrieving a value using its associated key can be accomplished using anindexer, which works just like an indexer for an array. A key is passed in asthe index value, and the value associated with the key is returned, unless thekey doesn’t exist, in which a null is returned.Write short code segment demonstrates how this technique works:
Campground reservations, part 3: Available campsites Excellent job! This next one's a little more challenging. Which campsites are available to reserve? We want to be able to quickly find which campsites are available. Can you help us? Given a campgrounds array, return an array with the campsite numbers of all currently unreserved (isReserved === false) campsites. Call the function availableCampsites. Dataset As a reminder, our data looks like this. It's an array with a bunch of campsite objects in it. Here is a small subset of the data to give you an idea: const campgrounds = [ { number: 1, view: "ocean", partySize: 8, isReserved: false }, { number: 5, view: "ocean", partySize: 4, isReserved: false }, { number: 12, view: "ocean", partySize: 4, isReserved: true }, { number: 18, view: "forest", partySize: 4, isReserved: false }, { number: 23, view: "forest", partySize: 4, isReserved: true }, ];
In cell C18 type a VLOOKUP function to find the corresponding letter grade (from column D) for the name in A18. The table array parameter is the same as in B18. Type FALSE for the range lookup parameter. Copy the formula in C18 to C19:C22Notice this formula works correctly for all cells. Range lookup of FALSE means do an exact match on the lookup value whether or not the table array is sorted by its first column. In cell E11, type an IF function that compares the score in B11 with the minimum score to pass in A5. If the comparison value is true, display Pass. Otherwise, display Fail. Copy the formula in E11 to E12:E15. Did you use appropriate absolute and relative references so the formula copied properly? In cell F11, type an IF function that compares the grade in D11 with the letter F (type F). If these two are not equal, display Pass. Otherwise, display Fail. Copy the formula in F11 to F12:F15
Determine if the following statement are true or false Screen shot shows the text's arraycollection When comparing two objects using the == operator, what is actually compared is the contents of the objects. The equals method of the Object class returns true only if the two objects being compared have identical attributes. A collection allows retrieval of information based on the size of the information. With the text's array-based collection implementation, the set of stored elements is scattered about the array.
value You are given 4 items as {value, weightpairs in this format {{20, 5}, {60, 20}, {25, 10}, {X, 25}}You can assume that the array is sorted based on the ratio. The weight capacity of knapsack is 50. The item no. 4 (whose weightis 25 ) is taken fractionally to fill upto the knapsack capacity. That fraction is represented in format. What is the lowest possible value of b? For the question above, assume the total value stored in the knapsack is 135 after you have filled upto the knapsack capacity. What is the value of X(in other words, the valueof the item no. 4) ? Give your answer to at least two decimal places.
QUESTION 4 UNi-Library is conducting a survey to rate the quality of their services in order to improve their services. In the survey, 30 students were asked to rate the quality of the service in the library on a scale of 1 to 5 (1 indicating very bad and 5 indicating excellent). You have to store the 30 responses of the students in an array named responses[ ]. Then, you have to count the frequency of each scale and store it in an array named frequency[ ]. Use the appropriate looping structure to enter the responses and to count the frequency. You are also required to display the percentage of the frequency of each scale. Display the scale, frequency and its percentage as shown below. The program also allows the user to repeat this process as often as the user wishes.
Grades 0-100 will be assigned randomly in a series with 30 elements. Taking their averages (shown on the screen), those above the average will be divided into an array and the ones below will be divided into an array by the function named "plenty" (two different sequences will be obtained). (Pointer is required.)Then, with the function named "gor", the grades of the whole class, those above the average, those below the average will be displayed on the screen.Write the C program code that performs the above operations.
Using the new operator, allocate an integer array of user specified size (the user gives the size of the array as input). Assign values to the array elements by taking user inputs and then print the values. Finally de-allocate the arrayusing the delete operator.
