The missionaries and cannibals problem is usually stated as follows. Three mission- aries and three cannibals are on one side of a river, along with a boat that can hold one or two people. Find a way to get everyone to the other side, without ever leaving a group of mis- sionaries in one place outnumbered by the cannibals in that place. This problem is famous in AI because it was the subject of the first paper that approached problem formulation from an analytical viewpoint (Amarel, 1968). a. Formulate the problem precisely, making only those distinctions necessary to ensure a valid solution. Draw a diagram of the complete state space. b. Implement and solve the problem optimally using an appropriate search algorithm. Is it a good idea to check for repeated states? c. Why do you think people have a hard time solving this puzzle, given that the state space is so simple?

Consider each's strengths and downsides. Which scenarios need an interpreter?

Hanry is a student. In School, there is a prestigious award so called a star. To be a star is not an easy task, a student with a good character only that can be called a star. In addition to that, a good character can be defined as a diligence and smart student. During his study, Hanry always present in all his subject and that makes him a diligence student. Not only that, Hanry also won award during his study, that makes him to get a predicate of smart student. Proves that Hanry is a star using backward chaining method!

Answer by true (T) or false (F) with a justification if false. Testing is the most time consuming and expensive part of software development Justification : Software testing depends on the size of the software being tested Justification : Software testing depends on the type of product being developed? (ex: experimental, life- critical) Justification : The existence of errors not detected by test cases in the modules does not necessarily imply the misbehavior of the system.
