Re: hierachical ai

: : : : For each state, we define a rating. : : : : : : What is a state? : : : : State (i.e. a situation) of the game. Does that clarify it? : : More or less. It still depends on what factors are included in the evaluation. The current 'goal' and 'subgoals' would need to be included in some way... : : : : http://c-evo.org/aiforum/2005/p-119-1.html : : : : I agree on the need for a hierarchical ai. However, in the example you give, the informations exclusively flows top-down. For instance, it would be the responsibility of the group manager to decide which city produces a unit. How would he decide that? This requires deciding between confliciting objectives, therefore, the relative importance of the requests needs to be specified. : : But the cities themselves don't know anything about 'the big picture'. There must be a manager above the cities to decide what they *should* do, in contrast to what they *want* to do, or even think they *need* to do. Take the extreme case where, for the greater good you may actually want to get rid of a certain city - no city manager would allow that. : : And it's the group manager that should know *where* the produced goods is needed, and *when*, and according to that put pressure on the 'best' city to do the job. : : : I think many low-level decisions dealing with economic optimization (e.g. exploited tiles management, improvement construction) do not benefit enough from setting goals themselves to justify the effort such planning requires. : : The individual city should combine the governement wishes and its own needs to decide what to do, maybe even ask for help from the governement. : : AI
