    "abstract": "A stochastic evolutionary dynamics of two strategies given by 2 x 2 matrix\ngames is studied in finite populations. We focus on stochastic properties of\nfixation: how a strategy represented by a single individual wins over the\nentire population. The process is discussed in the framework of a random walk\nwith arbitrary hopping rates. The time of fixation is found to be identical for\nboth strategies in any particular game. The asymptotic behavior of the fixation\ntime and fixation probabilities in the large population size limit is also\ndiscussed. We show that fixation is fast when there is at least one pure\nevolutionary stable strategy (ESS) in the infinite population size limit, while\nfixation is slow when the ESS is the coexistence of the two strategies.",
