1. A(n) _________ problem is one for which an algorithm exists which can give an optimal or near-optimal solution in finite time. Answer structured
2. A(n) _________ problem is one for which no algorithm exists which can give an optimal or near-optimal solution in finite time (often due to unknowns and variability). Answer unstructured
3. A(n) _________ problem is one for which partial solutions may be achieved, but for which variablity and unknowns may still change the expected outcomes. Answer semi-structured

Short answer

7. Define the term algorithm. Answer An algorithm is a step-by-step process for solving a problem.
8. Define the term model. Answer A model is a representation of reality.
9. What is an expert system? Answer An expert system is a computer application that emulates the knowledge of an expert in a narrow field/domain.
10. What is a neural network? Answer A neural network is hardware or software designed to mimic the way a brain works.
11. What is the Turing Test? Answer It is a test proposed by Alan Turing to determine if computers can think. To pass the Turing Test, a computer must have a dialog with humans and have the humans not be able to tell if they are talking to a computer or another person. To make the test a little more achievable, the dialog is almost always carried out as a text connection, like instant messaging or chat.
12. What is an intelligent agent? Answer An intelligent agent is software designed to wait to perform particular operations when triggered by a specific event, such as automatically reordering an item when the stock level of that item falls below a certain value.
