概要	The nested layer particle swarm optimization (NLPSO) is a new bifurcation analysis method that obtains a period dou- bling (PD) bifurcation point without the Newton-Raphson method. The NLPSO is performed by two particle swarm optimizers (PSOs) and is possible to obtain a PD bifurcation point without careful initialization. On the other hand, multi- ple bifurcation points generally coexist in the system param- eter space. Therefore, it is important for the bifurcation anal- ysis to effectively search for the multiple bifurcation points. In this study, we propose a modified NLPSO and confirm its effectiveness.
