We provide a mathematical method to determine the distribution of synaptic strengths formed by any types of spike-timing-dependent plasticity (STDP). This becomes possible by applying the theory of Ornstein-Uhlenbeck process in determining the Fokker-Planck equation that characterizes the distribution. We verify our novel method by reproducing quantitative properties of STDP observed in previous simulation results. We apply our method to CA1-type window function and electric fish-type window function to demonstrate possible implications of STDP. Moreover, we derive basic properties of STDP from our formalism. Especially, we determine the optimal window function for synaptic competition.
