Let P and Q be predicates on the set S, where S has twoelements, say, S={a, b}. Then the statement VxP(x) can also be writtenin full detail as P(a) A P(b). Rewrite each of the statements below in asimilar fashion, using P, Q, and logical operators, but without quantifiers.(a) Vx,y (P(x) ^ Q (y))(b) Vx3y (P(x) v Q (y))(c) 3x P(x)^3y Q(y)(d) ³xvy (P(x) ^ Q (y))

Run my function on {(1,4),(0,6),(3,5),(2,9),(7,8)}. Is the output what you expect? Find the problem and fix it, writing a correct version of the function. Again, use the same function name, i.e., count_crossings_and_nestings. Demonstrate that the new version works by testing it on the example provided. Now write a well-documented version of your function count_crossings_and_nestings. Add a document string and plenty of comments.
code a python function (sat) that solves the satisfiability of the clause set by running through all truth assignments. In case the clause set is satisfiable it should output a satisfying assignment. A full (truth) assignment should be represented by a list of literals.
Give a recursive definition for the set of all strings of a’s and b’s that begins with an a and ends in a b. Say, S = { ab, aab, abb, aaab, aabb, abbb, abab..} Let S be the set of all strings of a’s and b’s that begins with a and ends in a b. The recursive definition is as follows – Base:... Recursion: If u ∈ S, then... Restriction: There are no elements of S other than those obtained from the base and recursion of S.
Which of the following best describes the set of strings that are Boolean expressions (e.g., "not p or (q and r)"), with the precedence rules 'not' > ‘and' > ‘or' for the three logical operators, left-associativity is supported, and sub- expressions in parentheses are also allowed? A. {S→E, E→T|E or T, T→FIT and F, F→ G | not G, G → (E) I plq|r} B. { S→ E, E →TIE and T, T→ FIT or F, F→ G | not G, G → (E) I plq|r} C. {S → El not E, E → TIE and T, T→FIT or F, F→ (E) I plq|r} D. {S → El not E, E→TI E or T, T→FIT and F, F→ (E) Ip|q|r}
Consider the expression (6+3*4)/(7-1) In order to evaluate the expression it must be converted to Postfixnotation. Describe the process of conversion, then use that processto convert the above expression to Postfix. Note that if you don'tremember exactly how to process parenthesis, simply process them ina separate area until you get to the end of the parenthesized partof the expression. Then convert the expression to Postfix NOTE: You must show all work. Once you have your Postfix expression, now describe how to evaluateit. Then show the evaluation steps for the expression to generate afinal result. Again in order to get full credit you must show allwork.
The two most recent operands are popped in the postfix expression evaluation example whenever an operator is met so that the subexpression may be evaluated. In the subexpression, the first operand popped is regarded as the second operand, and the second operand popped as the first. Give a case study that exemplifies the significance of this component of the solution.
An argument is expressed in English below. The domain is the set of people attending a party. Every person who was late to the party left the party early. There is a person who was late to the party and was not happy. .. There is a person who left the party early and was not happy. The form of the argument is: x (P(x) → Q(x)) 3X (P(x) ^ ¬R(x)) .: 3x (Q(x) ^ ¬R(x)) Select the definitions for predicates P, Q, and R. P(x): Pick Q(x): Pick R(x): Pick
Let ∑={a,b} and T be the set of words in ∑* that have no consecutive a’s (i.e. there cannot be 2 or more a’s in a row). (a) Give a recursive definition for the set T. (b) Use your recursive definition to show that the string “abbaba” is in T. (c) Is your recursive definition uniquely determined? Explain why or why not.
The following argument is valid. ((A ∨ D) → W) (R ↔ (C ∧ T)) (← R → A) ← (B ∨ C) ∴ ← (W → C) Below is a natural deduction proof, but with some of the lines and justifications missing.
