Symmetric Nash equilibrium of political polarization in a two-party system
Jonghoon Kim, Hyeong-Chai Jeong, Seung Ki Baek
The median-voter hypothesis (MVH) predicts convergence of two party platforms across a one-dimensional political spectrum during majoritarian elections. From the viewpoint of the M…
Assortative clustering in a one-dimensional population with replication strategies
Sunhee Chae, Nahyeon Lee, Seung Ki Baek +1
In a geographically distributed population, assortative clustering plays an important role in evolution by modifying local environments. To examine its effects in a linear habitat,…
Sex-ratio bias induced by mutation
Minjae Kim, Hyeong-Chai Jeong, Seung Ki Baek
A question in evolutionary biology is why the number of males is approximately equal to that of females in many species, and Fisher's theory of equal investment answers that it is…
Long-range prisoner's dilemma game on a cycle
Jiwon Bahk, Seung Ki Baek, Hyeong-Chai Jeong
We investigate evolutionary dynamics of altruism with long-range interaction on a cycle. The interaction between individuals is described by a simplified version of the prisoner's…
Duality between cooperation and defection in the presence of tit-for-tat in replicator dynamics
Seung Ki Baek, Su Do Yi, Hyeong-Chai Jeong
The prisoner's dilemma describes a conflict between a pair of players, in which defection is a dominant strategy whereas cooperation is collectively optimal. The iterated version o…
Comparing reactive and memory-one strategies of direct reciprocity
Seung Ki Baek, Hyeong-Chai Jeong, Christian Hilbe +1
Direct reciprocity is a mechanism for the evolution of cooperation based on repeated interactions. When individuals meet repeatedly, they can use conditional strategies to enforce…
