e/Concurrent estimation

Information
has gloss	eng: In discrete event simulation concurrent estimation is a technique used to estimate the effect of alternate parameter settings on a discrete event system. For example from observation of a (computer simulated) telecommunications system with a specified buffer size B_0, one estimates what the performance would be if the buffer size had been set to the alternate values B_1,\ldots,B_n. Effectively the technique generates (during a single simulation run) n alternative histories for the system state variables, which have the same probability of occurring as the main simulated state path; this results in a computational saving as compared to running n additional simulations, one for each alternative parameter value.
