In this talk, I introduce a model of graph-constrained dynamic choice with reinforcement modeled by positively α-homogeneous rewards. Its empirical process, which can be written as a stochastic approximation recursion with Markov noise, has the same probability law as a certain vertex reinforced random walk. Thus, the limiting differential equation that it tracks coincides with the forward Kolmogorov equation for the latter, which in turn is a scaled version of a special instance of replicator dynamics with potential. This equivalence is exploited to show that for α>0, the asymptotic outcome concentrates around the optimum in a certain limiting sense when 'annealed' by letting α↑∞Ìý²õ±ô´Ç·É±ô²â.Ìý
