Figure 9

Performance metrics of simulated male moths seeking a pheromone source: variation with memory timescale, τ, and plume-crossing probability, P cross . Data and simulation parameters are as in Figure 7. Left: Search success probability, P success ; middle: time-based efficiency, E time ; right: distance-based efficiency, E distance . In all three plots, the horizontal axis represents memory timescale parameter, τ, and the vertical axis represents the plume-crossing probability, P cross . Note that success probabilities are maximized by intermediate values of P success . Both efficiency metrics are maximized by lower values of this parameter. Longer memory timescales (higher values of τ) broaden the range of P success corresponding to good source location performance, as indicated by all three metrics.
