MHB Solving Your Problem: Troubleshooting Mistakes in Code

AI Thread Summary
The discussion centers on the correct interpretation of quantifiers in logical statements, specifically regarding the scope of quantifiers in mathematical expressions. A key point raised is the convention that the scope of a quantifier is often considered maximal, meaning it extends as far to the right as possible. For example, the expression "for all y, if y is an Animal, then x loves y" is interpreted as "for all y, (Animal(y) implies Loves(x, y))" rather than "if for all y, Animal(y), then Loves(x, y)." This maximal scope interpretation is not universally accepted, as some textbooks advocate for a minimal scope approach. The discussion emphasizes the importance of understanding these conventions to avoid misinterpretation in logical reasoning.

As you can see I am not getting correct result. What have I messed up? I want to learn it.

Here is full slide in case anyone wants to refer to it.

The slides use the convention that the scope of a quantifier is maximal, i.e., it extends as far to the right as possible. In particular, $\forall y\,\text{Animal}(y)\Rightarrow \text{Loves}(x, y)$ means $\forall y\,(\text{Animal}(y)\Rightarrow \text{Loves}(x, y))$ and not $(\forall y\,\text{Animal}(y))\Rightarrow \text{Loves}(x, y)$, as you wrote in the first photo. This convention is not universal, however. Quite a few textbooks view the scope of a quantifier as being as small as possible.
 
Thread 'Star maps using Blender'
Blender just recently dropped a new version, 4.5(with 5.0 on the horizon), and within it was a new feature for which I immediately thought of a use for. The new feature was a .csv importer for Geometry nodes. Geometry nodes are a method of modelling that uses a node tree to create 3D models which offers more flexibility than straight modeling does. The .csv importer node allows you to bring in a .csv file and use the data in it to control aspects of your model. So for example, if you...
I tried a web search "the loss of programming ", and found an article saying that all aspects of writing, developing, and testing software programs will one day all be handled through artificial intelligence. One must wonder then, who is responsible. WHO is responsible for any problems, bugs, deficiencies, or whatever malfunctions which the programs make their users endure? Things may work wrong however the "wrong" happens. AI needs to fix the problems for the users. Any way to...
