The final sampling results were equivalent to those sampled by a conventional method, and the computational time conventionally wasted for the tracking of vanishing electrons was reduced drastically. The time saved can be utilized for tracking more samples to reduce statistical fluctuation. The efficiency of this technique and its limitation are discussed quantitatively together with details on its implementation.
