Reaction selection is a major and time consuming step of stochastic simulation algorithms. Current approaches focus on constant sets of reactions. However, in the case of multiple agents whose behaviors are governed by diverse reactions at multiple levels, with the number of agents the number of reactions varies during simulation. Therefore, we equip different variants of stochastic simulation algorithms with strategies to handle dynamic sets of reactions. We implement the next reaction method with a heap and the direct reaction method with two tree-based selection strategies, compare their performance, and discuss open questions for future research.
