Use a first-order language with two constants “−1” and “1”, the unary function s(x), denoting the “successor of x”, and the binary predicate Less(x, y), representing “x is less than y”. Consider the following Horn database, with two rules labeled A and B and fact C:
A. Less(x, y) => Less(x, s(y))
B. Less(s(x), y) => Less(x, y)
C. Less(s(−1), 1)
Using forward chaining (and substitution), begin enumerating all facts implied by fact C, given rules A and B, until you prove Less(−1, s(1)). Show all the facts you generated, starting with fact C.

2, M = 〈D, δ〉 is a model for a first-order language with a unary predicate P and a binary relation T. The domain of M is the set fa, b, c, dy; and the denotations of P and T are as follows: .8T) = {(a,b),(b,c),(c, d),(d,a)} Which of the following formulae are satisfied by this model: (a) 3x[T(x, x)] (c) Vr3y T(r, y) 2, M = 〈D, δ〉 is a model for a first-order language with a unary predicate...
Problem 3. Let C be the language 0, S, function symbol, and + is a binary function symbol. where 0 is a constant symbol, S is a unary (a) Let N be the C-structure with universe N = {0, 1,2, … } where 0N-0 and SN : N → N is the usual successor function and +N : N × N → N is the usual addition (that is, 3M (a) := a + 1 and +N(a, b) := a...
Logic Programming An important type of programming language is designed to reason using the rules of predicate logic. Prolog (from Programming in Logic), developed in the 1970s by computer scientists working in the area of artificial intelligence, is an example of such a language. Prolog programs include a set of declarations consisting of two types of statements, Prolog facts and Prolog rules. Prolog facts define predicates by specifying the elements that satisfy these predicates. Prolog rules are used to define...
1. Express in the language of the FOL the following mathematical statement: If S is a set of elements and * is a binary operation in S for which the following four assumptions hold, where = is an equivalence relation: a. S is closed under * ( if x and y are in S then x * y is also in S) b. * is associative (x, y, and z in S (x * y) * z = x *...
(1 point) The figure below gives F'(x) for some function F 4 5 Use this graph and the facts that the area labeled A is 9, that labeled B is 8, that labeled C is 2, and thatF(2) = 5 to sketch the graph of F(x). Label the values of at least four points. Then, using your graph, give four (x, y) points on the curve (Give your answer as a list of points separated by commas.) (1 point) The...
Initial Price of X can be assumed to be $1 2. Justin ‘s utility function for two goods, x and y, is U(x, y) = xy . The marginal utility of good x is y + 1 and the marginal utility of y is x. Initially, the price of good y is S4 per unit. Justin's income is $100. (a) If the price of good x rises to S5 per unit, what is the income effect with respect to good...

Suppose Louis monthly budget is 100 and the price of the two goods are (PT,PM) (4,2). (a) Make a properly labeled diagram illustrating Louis'budget constraint with T on the hori- zontal axis and M on the vertical axis. Indicate the area corresponding to the set of bundles (M, T) that Louis can afford. (b) What is the maximum...
