I'm trying to find a CPC bifurcation in a region of the parameter space that I know exists. The system I am studying is the Duffing equation with damping and forced externally. The system equation is in the 'System' image. I identified a limit cycle with a period between 30 and 40, the initial conditions for obtaining the limit cycle are: (x, y, u, v) = (0,0,1,0). And proceeded from it, this continuation (initializer init_LC_LC) generated the blue curve in the image, where LPC and PD bifurcations...
