This assignment uses several heuristic search techniques to find possibly optimal truth assignments for variables in the given Boolean formulas (see the bottom of the assignment). The formulas are in conjunctive normal form (ANDs of ORs). The fitness of an assignment is the number of clauses (ORs) that the assignment satisfies. If there are c clauses, then the highest fitness is bounded by c. However, if the formula is not satisfiable, then you cannot simultaneously make all c clauses true. You will use three of the following seven techniques: DPLL Resolution Genetic algorithms Local search Simulated annealing GSAT WalkSAT You must choose at least one complete algorithm to implement - DPLL or Resolution.

A university assigns student IDs of the form 1, 2, 3, ... such that if n students are currently enrolled, then the next student to enroll will receive and ID of n + 1. Consider the following algorithm that accomplishes this. // Global variable storing number of students currently enrolled current_student_count = 0 // Function that reads the above global variable, calculates new ID, and increments the global count assign_new_id(): count = current_student_count new_id = count + 1 current_student_count = count + 1 return new_id (a) If two different threads run the above code in parallel to enroll two different students, it is possible for the two students to receive the same ID, and for the current_student_count to have a wrong value. Explain how this is possible. (b) Modify the code above so that the problem in (a) does not happen.
We can specify the PageRank algorithm's convergence threshold using proc networks. This figure has to be positive. Default value is 1E-9. When the difference between the PageRank scores of the current iteration and the previous iteration is less than or equal to the tolerance set, the PageRank algorithm ceases iterating. We can use the PAGERANKTOLERANCE= parameter to specify the convergence tolerance. Write The example code demonstrates how to calculate PageRank centrality using a proc network built on a directed graph with unweighted links.
Given two strings A and B and the following operations can be performed on A. Find a minimum number of operations required to make A and B equal. (Please Design a dynamic programming algorithm that can use the following operations to make A equals to B and analyze the complexity. Assume the size of the string is n.). When designing the dynamic programming algorithm, please describe the size and dimensionality of the dynamic programming table, and explicitly formulate the recurrence relationship. 1. Insert 2.

Using pyhton coding to solve: Suppose the Great Frederick Fair wants to update its ticketing software. They need you to write a program to handle the price calculations, using the rules*: ● The basic price of a ticket is $40. Senior citizens (age >= 65) get a 50% discount. Children under 6 are free (100% discount). For residents of Frederick County, the basic price is $35; the same discounts still apply. So the individual ticket prices range from $0 to $40. ● . Your program should request age and county name from the user. The age will be entered as an integer and the county name as a string. Before calculating the price, confirm that the user's age is valid - not negative and not more than 110. If it is not, give a message and do not do the price calculation. Also, the county name should not be case sensitive - for example, Frederick, frederick, and FREDERICK should all be acceptable. Your program should then calculate and print out the ticket price, using the appropriate…
