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?
