You're tasked with implementing a computer player for a real-time strategy (RTS) game. Assuming that there is no fog-of-war, how do you implement a system to allow the computer player to determine what parts of the map are controlled by enemy players, and which parts are open to easy exploitation? How do you identify the choke points on the map? How do you find the boundary between the parts of the map under your control and the parts of the map controlled by enemy players? How do you detect an impending enemy attack or a change in an enemy's offensive posture?

Raja was studying for his examinations and the lights went off. It was around 1:00 AM. He lighted two uniform candles of equal length but one thicker than the other. The thick candle is supposed to last six hours and the thin one two hours less. When he finally went to sleep, the thick candle was twice as long as the thin one. For how long did Raja study in candle light?

You have an AI player in an RTS game that occasionally needs to send scouts out onto the map to perform reconaissance. Designers want each scout to move around semi-randomly, exploring various parts of the map, particularly those that have been seen the least recently. Assume that the game is grid-based and has a fog-of-war feature. Also assume that the scouts are very cheap and dispensable, and it's OK for them to walk into the enemy base or other dangerous areas. How would you implement the system to decide where the scouts should go? What sort of data structure do you need to support this? How can you ensure that the scouts do a good job of exploring the map thoroughly? What are the performance characteristics of your approach? Is there any risk of scouts getting stuck trying to go somewhere that isn't even accessible?
