Fig. 7: The effects of alliance propensity to unity and disunity.
From: Human civilization dynamics: why we have different civilization patterns in history

A shows the number of states under different alliance propensity. The green triangles represent the disunity pattern, and the turmeric dots represent the unity pattern. The table in A shows the proportion of unity and disunity under different alliance propensities. B is a Decision Tree with CART to classify unity and disunity under different alliance propensities from 0 to 1.
