if we transform the 4-color map problem

into density.

we know that there are only 4 complete structures

k1,k2,k3 and k4.

for any region, assign its density to be the Max of the 4 structures it
belongs to.


all the same density connected regions will merge into one unless they are
separated.

then we only have 4 different densities.

in density problem, the Max=4

for K-4 structured maps(isomorphism?), it is 4-colorable.

: 女生说说看，你们怎么表示，做了些什么最让男生心动？

这种事情,一定要有一定的基础,即互有好感.

成功率=男对女好感系数 * 女对男好感系数.

比如:
1*1=1 干柴烈火
0 * 1= 0, 悲惨的单恋.

0.8*0.8=0.64 , 互有好感, 有一方主动,较易成功.

0.95* 0.2=0.19 单恋+寂寞. 只会失短暂的故事.
