Exercise 3

Consider the decision-making situation defined by the following rules:

If it is a nice day and it is summer, then I go to the golf course.
If it is a nice day and it is winter, then I go to the ski resort.
If it is not a nice day and it is summer, then I go to work.
If it is not a nice day and it is winter, then I go to class.
If I go to the golf course, then I play golf.
If I go to the ski resort, then I go skiing.
If I go skiing or I play golf, then I have fun.
If I go to work, then I make money.
If I go to class, then I learn something.

Follow the rules for the following situations (what do you conclude for each one?):
- It is a nice day and it is summer.
- It is not a nice day and it is winter.
- It is a nice day and it is winter.
- It is not a nice day and it is summer.
Are there any other combinations that are valid? Explain.
What needs to happen for you to “learn something” in this knowledge universe? Start with the conclusion “learn something” and identify the rules used (backward) to get to the needed facts.
Encode the knowledge into a graphical diagram (like an influence diagram). Use a circle to represent a fact such as:

The day is nice or

The day is not nice and an arrow to indicate influence.
