Solving Missionaries and Cannibals problem:

First let us consider that both the missionaries (M) and cannibals(C) are on the same side of the river.

Left Right

Initially the positions are: 0M 0C and 3M , 3C (B)

Now let’s send 2 Cannibals to left of bank: 0M , 2C (B) and 3M , 1C

Send one cannibal from left to right: 0M , 1C and 3M , 2C (B)

Now send the 2 remaining Cannibals to left : 0M , 3C (B) and 3M , 0C

Send 1 cannibal to the right : 0M , 2C and 3M , 1C (B)

Dijkstra's Algorithm (part 1). Consider the network shown below, and Dijkstra’s link-state algorithm. Here, we are interested in computing the least cost path from node E (note: the start node here is E) to all other nodes using Dijkstra's algorithm. Using the algorithm statement used in the textbook and its visual representation, complete the "Step 0" row in the table below showing the link state algorithm’s execution by matching the table entries (i), (ii), (iii), and (iv) with their values. Write down your final [correct] answer, as you‘ll need it for the next question.
