[QUOTE="clearstream, post: 9027239, member: 71699"] Not generally incomplete. Always incomplete. To model something is to represent it incompletely. It would be a worse simulation than one with the same predictive power that took half the time and energy. And one that did not finish processing until after the event being projected would be worthless (setting aside backcasting.) If the models you have in mind couldn't be run at the game table, they are worthless in that context. Efficiency is at issue. It's right to specify "relevant" as not all data has equal impact on a model's success. Failure to include the most relevant data and dynamics can scupper a model no matter the thickness of its other data and dynamics. So if by thinness you mean the bolded part, then with regard to imagined worlds enough of the [I]most relevant[/I] data is in place. That was the poster's point. Perhaps generally you are supposing that models of imagined worlds should play by the same rules as military, economic or scientific models of the real world. It's better to see them as comparatively simple functions. Efficiency is crucial as you normally want quick answers without too much pondering. [/QUOTE]
