N : the number of Kuramoto oscillators. The button 'Init' makes all simulation setting initialize. 'd' sets the size of oscillator. The slider bar 'speed' controls simulation speed. The check box 'Edge' switches showing edges. The green dot in the ρ-Δ plot indicates current values of (ρ,Δ) at simulation time. 1. The Kuramoto model consists of N coupled phase oscillators φi(t) having natural frequencies ωi. Here, ωi is distributed by Gaussian function with μ=0 and σ2=1. Their dynamics are governed by dφi/dt=ωi+K/N Σj=1Nsin(φi-φj) 2. The oscillators are fully connected and each edge is periodically switched. If a edge between node i and j has a value, calculated by following equation, larger than 0, then node i and j are connected. Otherwise, they are disconnected. Here, θij is randomly selected from [0,aπ] and a=[1.0,2.0]. sin(Ωt+θij) Reference) Sang Hoon Lee, Sungmin Lee, Seung-Woo Son, and Petter Holme, Phys. Rev.
