7. 15 Points For a regular expression r, we use L(r) to denote the language it represents. For each of the following regular expressions r, find an NFA that accepts L(r). (b). L((a +b+A) b(a bb)) し(((aa 7. 15 Points For a regular expression r, we use L(r) to denote the language it represents. For each of the following regular expressions r, find an NFA that accepts L(r).

Thanks for the help in advance. 2. To transform the following NFA into a regular grammar, b a we first construct A-closures of the given NFS's states A(0) 10, 1, 3), A(1) {1, 3), A(2) 12), A(3) 313), Then, build the following tree: (7 points) A(0) (0,1,3 Distinct nodes of the tree are: (2 points) (0,1,3)
Given breadth first search function as below. Write a bfs_new(a_tree, start, goal), which does the following. We store one additional dictionary variable, called parent, to store the parent of each node. In the beginning, set parent = { start: 'NOBODY'}. Each time that a node is expanded, we add one entry in parent for each of its children. The input goal is the name of a node; if bfs_new reaches the node called goal, then the search is terminated, and...
3 points) Question Three Consider the context-free grammar S >SS+1 SS 1a and the string aa Give a leftmost derivation for the string. 3 points) (4 poiots) (5 points) (3 points) sECTION IWOLAttcmpt.any 3.(or 2) questions from this.scction Suppose we have two tokens: (1) the keyword if, and (2) id-entifiers, which are strings of letters other than if. Show the DFA for these tokens. Give a nightmost derivation for the string. Give a parse tree for the string i) Is...
Objective The objective of this assignment is to get you familiar with regular expression, word tokenization and sentence segmentation. Given a text document, your goal is to segment the document into separate sentences. An example input/output pair is provided below. Input It also means that we've got to make sure that young people like yourself are able to afford a college education. Earlier, Governor Romney talked about—he wants to make Pell grants and other education accessible for young people. Well,...
K-means clustering Problem 1. (10 pts) Suppose that we have the gene expression values for 5 genes (G1 to G5) under 4 time points (t1 to t4) as shown in the following table. Please use K-Means clustering to group 5 genes into 2 clusters based on Euclidean distance. Find out the final centroids and their affiliated genes. The initial centroids are c1=(1,2,3,4) and c2=c(9,8,7,6). Please write down your algorithm step by step. Result without steps won't get points. t1 t2...
Part B - Automata Construction Draw a DFA which accepts the following language over the alphabet of {0,1}: the set of all strings such that the number of 0s is divisible by 2 and the number of 1s is divisible by 5. Your DFA must handle all intput strings in {0,1}*. Here is a methodical way to do this: Figure out all the final states and label each with the shortest string it accepts, work backwards from these states to...
Can you make simple code of this using C++ In-lab Final Exam Ideas: Following are the possible topics for the in-lab final exam for next week. These all assume that we have: struct Node int data; Node 'pNext; and in main we have: Node "pHead = NULL; // pointer to the head of the list Node·pTemp: // Used to get new nodes Node "pHeadA NULL: Node "pHeadB = NULL; We will also provide for you the code that is used...
Infix Expression Evaluator For this project, write a C program that will evaluate an infix expression. The algorithm REQUIRED for this program will use two stacks, an operator stack and a value stack. Both stacks MUST be implemented using a linked list. For this program, you are to write functions for the linked list stacks with the following names: int isEmpty (stack); void push (stack, data); data top (stack); void pop (stack); // return TRUE if the stack has no...
