Question

Hard enough, but intresting puzzle:

"Two commanders (Caesar and Brutus) conquer a country which forms a connected digraph with nodes representing cities and edges representing roads. First, Caesar chooses a city and claims it. Then, Brutus claims any of the remaining cities. Turn by turn, the commanders claim the available cities that are adjacent to the cities they have already claimed. If a commander cannot make a claim, he skips a move. The game continues until all cities have been claimed. Both commanders wish to claim a maximal number of cities. Can Brutus win in this game?"

I don't think Brutus can win... best he can do is tie if there are even number of nodes (cities). Played a bit with nodes only on perimeter (outer edge of country) or with bisectors and seems to work out same.

There is no best. Brutus win or lose.

And perimeter of such country is hard to define too.
