Suppose you are given a timetable, which consists of the following: • a set a of n airports, and for each airport a ∈ a, a minimum connecting time c(a) • a set f of m flights, and the following, for each flight f ∈ f: – origin airport a1(f) ∈ a – destination airport a2(f) ∈ a – departure time t1(f) – arrival time t2(f). describe an efficient algorithm for the flight scheduling problem. in this problem, we are given airports a and b, and a time t, and we wish to compute a sequence of flights that allows one to arrive at the earliest possible time in b when departing from a at or after time t. minimum connecting times at intermediate airports should be observed. what is the running time of your algorithm as a function of n and m?

Signal sets company contracts to deliver one hundred 52-inch plasma high-definition television sets to a new retail customer, tuner tv store, on may 1, with payment to be made on delivery. signal tenders delivery in its own truck. tuner's manager notices that some of the cartons have scrape marks. tuner's owner phones signal's office and asks whether the sets might have been damaged as they were being loaded. signal assures tuner that the sets are in perfect condition. tuner tenders signal a check, which signal refuses, claiming that the first delivery to new customers is always for cash. tuner promises to pay the cash within two days. signal leaves the sets with tuner, which stores them in its warehouse pending its "grand opening sale" on may 15. two days later, tuner's stocker opens some of the cartons and discovers that a number of the sets are damaged beyond ordinary repair. signal claims tuner has accepted the sets and is in breach by not paying on delivery. will signal succeed on these claims? explain.
