a.
Explanation of Solution
Recursive
- The language has built-in Boolean operators not,and,or and if.
- The algorithm is
function PL-TRUE?(s,m) returns true or false
if s = True then return true
else if s = False then return false
else if SYMBOL?(s) then return LOOKUP(s,m)

Explanation of Solution
Sentences
- All the sentences can be determined to be true or false...
c.
Explanation of Solution
Truth value
- A general algorithm for partial models must handle the empty partial model, with no
assignments...

A robot moves in a 2D lattice. The robot can only move north (N), south (S), east (E), and west (W)
by a certain number of steps. Assume that the robot always starts at (0,0), and that the x axis is
oriented east, while the y axis is oriented north. Write a Python function that, given a set of moves,
calculates the final position of the robot.
For example, if the set of moves provided as input is:
N 2
E 4
S 1
W 3
then the final position of the robot is (1,1). The integer that follows a move is always positive.
Follow this code skeleton:
def robot_move (moves):
X = 0
y = 0
# your code here
return (x,y)
The moves are provided as an array of tuples. The array can have any number of moves in any order.
The example above is passed as input as follows:
[('N',2), ('E',4), ('S',1), ('W',3)]

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.

- Your main task is to write a recursive function sierpinski() that plots a Sierpinski triangle of order n to standard drawing. Think recursively: sierpinski() should draw one filled equilateral triangle (pointed downwards) and then call itself recursively three times (with an appropriate stopping condition). It should draw 1 filled triangle for n = 1; 4 filled triangles for n = 2; and 13 filled triangles for n = 3; and so forth.

- The next question has to do with a bisection process, which is very common in mathematical software. For example, the bisection method for finding a root of a function starts with an interval, [a, b], where f(a) and f(b) have different signs. It then computes the midpoint of the interval, c = (a + b) / 2. It then replaces either a or b by c so that the signs of the new f(a) and f(b) are still different, thus guaranteeing that the new interval [a, b], which is either the left or right half of the previous interval, still brackets a root. In the next 2 questions, assume B = 2 and p = 24. 13. If a = 1 and b = 2, how many times can bisection occur before there are no floating-point numbers in the interval (a, b) (in other words, a and b are adjacent floating-point numbers)?arrow_forwardPlease send me answer of this question with explanation immediately and i will give you like sure sirarrow_forwardAnswer the given question with a proper explanation and step-by-step solution.arrow_forward
