What does the term microsimulation refer to?

Microsimulation refers to detailed simulations that focus on individual components or small units within a larger system, often incorporating complex variables and interactions. In this context, considering the options, the idea of microsimulation aligns with a format that involves smaller, more discrete units of simulation which can be executed on personal devices like laptops or through web interfaces. This aligns with the nature of microsimulation as it often allows users to engage with scenarios in a manageable and accessible manner, emphasizing the focus on smaller-scale, individualized components.

While the other options refer to broader categories of simulation types, they do not capture the essence of microsimulation, which is distinctly about the granularity and modularity of the simulation experience. For instance, physical simulations typically encompass larger, more integrated environments rather than the focused detail inherent in microsimulation. Similarly, high-fidelity simulation is characterized by highly realistic scenarios that often require significant resources, which deviates from the more compact and often simpler applications associated with microsimulation. Mixed simulation conflates various forms of simulation without honing in on the particularities of microsimulation as a separate, distinct approach.
