Smaller parameter search using heroin and benzphetamine as index terms. Each combination of temperature, frequency penalty, and presence penalty was used to conduct 1000 iterations of the query pipeline. The number of UNGSes generated by the 1000 iterations was recorded for each index term and parameter set. Each subfigure shows the distribution of UNGSes for both heroin and benzphetamine for each value of (a) temperature; (b) frequency penalty; and (c) presence penalty.
