Consider a version of the semantics for first-order logic in
which models with empty
domains are allowed. Give at least two examples of sentences that
are valid according to the standard semantics but not according to
the new semantics. Discuss which outcome makes
more intuitive sense for your examples

Suppose that we add a new quantifier called exists unique to first- (d) order logic, using the symbol 3! to represent it. It means that there is exactly one element of the universe that satisfies the subsequent formula. In this question, variables will range over the universe of numbers. [1 mark] (0) Is 3!x. x + x 2 valid? Why? Give an example of a valid formula that uses the quantifier, and an example of an unsatisfiable one. Both must...
consider this first- order logic formula: ∃x P(a,x) --> ∀y P(b,y) and its interpretation which is: Domain D = {1,2,3}, P{(1,1), (1,2), (1,3), (2,3), (3,1)}, a=1, b=3. is it valid, satisfiable, or contradictory? why?

I think I can pinpoint my confusion a bit better. Here comes my updated question (I'm not sure what the standard way of doing things is - please let me know if I should delete the old version). The major change is that I removed focus from the third question which probably is a purely mathematical question (in the notation below, it asks what properties of (M,T) together with (M,T) being consistent, forces (M,T) to be unique.). Say that a...
Please help i need a C++ version of this code and keep getting
java versions. Please C++ only
Purpose: This lab will give you experience
harnessing an existing backtracking algorithm for the eight queens
problem, and seeing its results displayed on your console window
(that is, the location of standard output).
Lab
A mostly complete version of the eight queens problem has been
provided for you to download. This version has the class Queens
nearly completed.
You are to provide...
Original Source Material Student Version First, the potential of digital games is discussed using the tutor/tool/tutee framework proposed by Taylor (1980). Second, the potential of digital games to enhance learning by connecting game worlds and real worlds is stated. Third, the possibility of digital games to facilitate collaborative problem-solving is addressed. Fourth, the capability of digital games to provide an affective environment for science learning is suggested. Last, the potential of using digital games to promote science learning for younger...

4. Columns is a video game available on the Sega Gen- esis system. In the flashing version of the game, the player attempts to capture a flashing block in the bottom row of the screen as quickly as possible. The game may be played at levels 2 through 9. The level denotes the number of complete rows of blocks on the screen at the beginning of the game. For example at level 2 the player must break through the second...
