You wish to drive from point A to point B along a highway minimizing the time that you are stopped for gas. You are told beforehand the capacity C of you gas tank in liters, your rate F of fuel consumption in liters/kilometer, the rate r in liters/minute at which you can fill your tank at a gas station, and the locations A = x1, ··· , B = xn of the gas stations along the highway. So if you stop to fill your tank from 2 liters to 8 liters, you would have to stop for 6/r minutes. Consider the following two algorithms: (a) Stop at every gas station, and fill the tank with just enough gas to make it to the next gas station.

Question
You wish to drive from point A to point B along a highway minimizing the time that
you are stopped for gas. You are told beforehand the capacity C of you gas tank in liters,
your rate F of fuel consumption in liters/kilometer, the rate r in liters/minute at which you
can fill your tank at a gas station, and the locations A = x1, ··· , B = xn of the gas stations
along the highway. So if you stop to fill your tank from 2 liters to 8 liters, you would have
to stop for 6/r minutes. Consider the following two algorithms:
(a) Stop at every gas station, and fill the tank with just enough gas to make it to the next
gas station.
(b) Stop if and only if you don’t have enough gas to make it to the next gas station, and
if you stop,fill the tank up all the way.
For each algorithm either prove or disprove that this algorithm correctly solves the problem.
Your proof of correctness must use an exchange argument.
