The missionaries and cannibals problem is usually stated as follows: three missionaries and three cannibals are on one side of a river, along with a boat that can and must hold either one or two people. find a way to get everyone to the other side without ever leaving a group of missionaries 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
a. formulate the problem precisely, making only those distinctions necessaryto 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 chcek for repated states?
c. why do you think people have a hard time solving this puzzle, given that the state space is so simple?

Apex q: what does a low employment rate indicate? a. not many people are earning high salaries b. not many people are going to college c. not many people are renting their homes d. not many people have jobs

Consider a slotted aloha system, where the time slot equals the fixed duration of each packet. assume that there are 4 stations a,b,c,d sharing the medium. (a) stations a,b,c,d receive one packet each from higher layers at times 1.3, 1.5, 2.6,5.7 respectively. show which transmissions take place when, according to the slottedaloha protocol; describe all transmissions until all four packets have been successful.when needed, each station has access to the following sequence of random number, provided by a random number generator and drawn uniformly between 0 and 1: (1) station a draws numbers: 0.31, 0.27, 0.78, 0.9, 0.9, 0.11, 0. (2) station b draws numbers: 0.45, 0.28, 0.11, 0.83, 0.37, 0.22, 0. (3)station c draws numbers: 0.1, 0.2, 0.3, 0.4, 0. (4) station d draws numbers: 0.36, 0.77, 0.9, 0.1, 0.1, 0.1, 0.1, 0. (b) in slotted aloha, a station transmits in each time slot with a given probability. what probabilities would you assign to each of the four stations so as to: (i) maximize the efficiency of the protocol? (ii) maximize fairness among the four stations? (c) will the efficiency increase or decrease if we modify slotted aloha as follows: (i) get rid of slots and allow stations to transmit immediately? (ii) implement carrier sensing? (iii) implement collision detection? (iv) implement collision avoidance?
