Program Plan Intro

Heuristic search:

It denotes a technique to reach goal state by choosing best promising state.

It leads to goal state and this search is identified as heuristic search.

The heuristic values are chosen for each node.

It denotes that node that has low heuristic value is been chosen over another nodes.

Goal:

The objective is to find state sequence that would lead to final state.

The numbers are been ordered from initial state that is unordered and it follows the productions.

The count of tiles that are out of place denotes heuristic in problem.

Algorithm for creating search tree:

The algorithm is shown below:

Step 1:

Construct parent node by taking initial node

Step 2:

Check whether the node signifies a final state.

Step 3:

If step 2 fails, make child nodes that are possible states and could be attain by moving empty tile in parent nodes.

Find heuristic value of states.

Select node that has low heuristic value and move to step 2.

Step 4:

If step 2 is true, then algorithm constructed search tree.

Stop construction of tree further.

In this assignment, you will implement a multi-threaded program (using C/C++) that will check for Prime Numbers and Palindrome Numbers in a range of numbers. Palindrome numbers are numbers that their decimal representation can be read from left to right and from right to left (e.g. 12321, 5995, 1234321). The program will create T worker threads to check for prime and palindrome numbers in the given range (T will be passed to the program with the Linux command line). Each of the threads works on a part of the numbers within the range. Your program should have some global shared variables: • numOfPrimes: which will track the total number of prime numbers found by all threads. numOfPalindroms: which will track the total number of palindrome numbers found by all threads. numOfPalindromic Primes: which will count the numbers that are BOTH prime and palindrome found by all threads. TotalNums: which will count all the processed numbers in the range. In addition, you need to have arrays…
