1. Anthony, Bob, Christina, and Diane sit around a table that has four seats: North,
East, South and West. We have the following information:
1. Anthony is seated south.
2. Diane sits opposite to Bob.
3. Exactly one of Bob’s neighbors has a glass.
4. A glass stands on the table positioned north.
5. If Diane has a glass then her two neighbors have a glass as well.
6. The neighbor to Anthony’s right (from his point of view) has a glass.
You have the task to model the given situation with the help of formulas of
propositional logic. Use the following variables:
{xy|x 2 {A,B,C,D}, y 2 {N,O, S,W}} = {AN,AO,AS,AW,BN, ...,DS,DW}
For example, the variable AN is true, if and only if Anthony is seated North
of the table. Furthermore, the variables {A,B,C,D,N,O, S,W} can be used to
describe the position of the glasses: The variables A ... D are true, if and only if
there is a glass in front of person A ... D, respectively. The variables N ... W are
true, if and only if there is a glass at the respective position on the table.
Write formulas of propositional logic to model the information (1) to (6) given
above. (Remember that you can use implications!)
Resolution
Knowledge: W = (X _ F _ ¬M _ R) ^ (¬F _ X _ B) ^ (¬R _ ¬F _ X _ ¬B) ^
(X _ F _M) ^ (X _ ¬M _ ¬R _ F) ^ (¬F _ X _ R _ ¬A _ ¬B) ^ ¬X
Hypothesis: H = ¬(¬F _ X _ ¬B _ R _ A)
Question: Does W |= H hold?
Apply the resolution method! (Note that the hypothesis is already nearly in
CNF; just remove the first negation and start the resolution.)
