- Suppose a pail holds 12 quarts of water, the two jars hold 7 quarts and 5 quarts, and the goal is still to split the water evenly with 6 quarts in both the pail and the larger jar. Produce a complete graph model for this puzzle, and find all solutions to the water puzzle in terms of the properties of the graph.Among each pair of the CEOs of N companies there is (a) mutual like; (b) mutual dislike; (c) neutral feeling. A trade delegation of the maximum size needs to be formed such that it does not have any pair of members with mutual dislike. Transform this problem to a graph theoretic problem. What are the vertices of the graph? What are the edges of the graph? What do you have to find in the graph?
