In order to reproduce both transient dynamics and space distribution of an urban population only derived from a simple self-organism principle, a multi-agent simulation model is established. A resident agent tries to move to a cell so as to maximize his own utility that is defined by both effects of distance from the urban central and population density. The so-called "doughnut phenomenon" as well as growing Densely Inhabited District (DID) can be emulated qualitatively, even though the model bases on a simple self-organism rule.

We deduced that it is possible to define the Dilemma substance in the so-called dilemma games by the fact, a cooperative strategy cannot be dominant. This simple but clear definition can provide a firm way to a quantitative evaluation for the dilemma intensity in order to compare other types of dilemma games, for example, between Chicken and Leader Game. On the pathway of our deductive discussion, two important concepts concerning the Pareto Least and a parameterized expression procedure for the game structure were presented. In particular, the latter concept seems to be quite breakthrough to overview holistic 2×2 game world including Prisoners Dilemma, Chicken, Stag Hunt, Leader and Hero Game. And a practical explanation going through 2×2 game was presented about what we defined as the dilemma substance seems to be plausible from the viewpoint of the Replicator Dynamics.
