Question: Given the productions in a phrase-structure grammar, determine which type of grammar this is in the Chomsky classification scheme.
FIT2014 - Assignment - Legal and almost-legal positions can be counted using the scheme and How much can you improve on these upper bounds? In particular, can you reduce the 2.8 to a smaller number? If so, what can you reduce it to?
For questions 3 to 5, remember that a Turing machine starts in state 1, reading the leftmost nonblank cell.
left recursive EBNF grammar into an equivalent non-left recursive grammer
Devise a Turing machine with input given in unary notation (i.e., a string of n 1's denotes the integer n, and numbers are delimited by 0's) such that the machine produces the following output:
Show that if the costs associated to the arcs of a complete directed graph G satisfy the triangle inequality property, then there exists in G' an ATSP optimal solution which is a Hamiltonian tour.
Express each of these sets using a regular expression. The set of strings of one or more 0s followed by a 1.
Construct a TM that recognizes the non-CFL language L = {wcw | w is in (0+1)*} and halts on all inputs. Please briefly explain the purpose of each state of your machine. So, for example the string 1110c1110 IS in L but the string 0010c0110 is NOT.
Construct a deterministic finite-state automaton that recognizes the set of all bit strings beginning with 01.
If M is a DFA accepting language B, then exchanging the accept and reject states gives a new DFA accepting the complement of B.
Draw a PDA using JFLAP for the language - Use JFLAP to draw a PDA for the language defined in question #3 - The final step in producing the CNF grammar is to reduce right-hand sides of the productions with more than 2 variables to multiple productio..
Construct a deterministic finite-state automaton that recognizes the set of all bit strings that contain an even number of 0s and an odd number of 1s.
What is the language generated by the grammar G with vocabulary {S, 0, 1}, set of terminals T = {0, 1}, starting symbol S, and productions S ? 000S, S ? 1?
