How's this for an algorithm basis on CTF: 1 - The early ending goes off when the number of flags needed to even the score is impossible to obtain during the time left. This would be calculated by multiplying the number of flags needed by the time it takes the fastest tank (available to the highest rank possible for that battle), through the fastest route on that map, to get from the closest spawning site to the enemy flag and then to own flag. 2 - The early warning goes off if the player ratio blue/red or red/blue is below 0.5 after 1/3 of the game's intended time. 3 - Once the early ending has been triggered, there is no going back! Even if the conditions that triggered it are no longer true.
