- Devise a branch-and-bound algorithm for the SET COVER problem. This entails deciding: (a) What is a subproblem? (b) How do you choose a subproblem to expand? (c) How do you expand a subproblem? (d) What is an appropriate lowerbound? Do you think that your choices above will work well on typical instances of the problem? Why? In its current iteration, does this backing representation, which is just a two-dimensional singly linked list, have any advantages or disadvantages? Explain with regard to the implementation, performance, and the consumption of memory in general, as well as in contrast to a two-dimensional dynamic sequence implementation that makes use of two dimensions and is based on a linked list.Is it feasible to use a DLL to implement a sorted linked list? What is the advantage of a DLL implementation over a singly linked list? Use a concrete example or application to back up your claim.

Format your paper according to appropriate course-level APA guidelines.The MWT introduced in class has an array of pointers to children nodes in each node, and the index is used to indicate the letter on the edge. If instead we use a BST (each BST node contains a letter, a corresponding child MWT node pointer) in each MWT node, explain the advantages and disadvantages of this new “MWT” compared to the one introduced in class.
- A priority queue is implemented as a linked list, sorted from largest to smallest element. a. How would the definition of PQType change? b. Write the Enqueue operation, using this implementation. c. Write the Dequeue operation, using this implementation. d. Compare the Enqueue and Dequeue operations to those for the heap implementation, in terms of Big-O notation.Problem 1: Consider an array-based queue implementation. Suppose we wish to use an extra bitin queue records to indicate whether a queue is empty.1. Modify the declarations and operations for a circular queue to accommodate this feature.2. Would you expect the change to be worthwhile?Problem 2: Consider an array-based queue implementation. A variant of the circular queuerecords the position of the front element and the length of the queue.1. Is it necessary in this implementation to limit the length of a queue to maxlength - 1?2. Write the five queue operations for this implementation.3. Compare this implementation with the circular queue implementation discussed in class.Problem 3: A dequeue (double-ended queue) is a list from which elements can be inserted ordeleted at either end.1.
