Due to the low computational cost of loops in Julia, the simulation achieves high performance and efficiency. Furthermore, advancements in computational technology have greatly accelerated random number generation. For the parameters used in this study, the traditional SSA simulation for FRP can be completed in just one minute. The CLD for a typical FRP system was obtained [Figure ]. It can be observed that for FRP systems, molecular chains continue to accumulate and PDI continues to increase, while for DT systems, molecules can be observed The chain length gradually increases with the increase of monomer conversion rate. PDI first decreases and then increases.
