- Here is a game:
- There are two countries. Each country has different number of cities and
- ONE traveller. Each traveller only travels within his own country. The
- path between two cities can be two way, one way or "conditional", for
- instance, traveller A can travel from his city 1 to city 2 only if traveller
- B is in city 5 of the other country. Given such two countries with cities,
- roads, and conditions defined, also given the initial position of the two
- travellers, here is the question:
- Which cities are reachable? or pick one city and ask if it is reachable?
- Are there some theory dealing with this kind of problem? The number of
- countries can be greater than 2. Travellers can move simultaneously or
- one at a time. The path condition is always defined in terms of other
- traveller's positions at that time. The travelling between two cityes
- takes no time.
