Evolution of semi-major axis (top), eccentricity (middle) of the SMBH binary and energy error (bottom) for the several different valuse of \(\pmb{\Delta t_{\mathrm{soft}}}\) . Thick solid, dashed and dotted curves show the results of \(\mathrm{P}^{3}\mathrm{T}\) scheme with \(\Delta t_{\mathrm{soft}}\) is less than \(t_{\mathrm{kep}}/4\), \(t_{\mathrm{kep}}/2\) and \(t_{\mathrm{kep}}\), respectively.
