(a) Saturation time TS as a function of p in an exponential random environment with parameter 0.43 (see (b)), for μb = 3.886. (b) Adaptation probability for the optimal p from (a) (blue) and fixed repair probability (orange). The dashed curve represents the exponential probability density of the random environment. (c) Saturation time TS as a function of p with uniform random delay over [1, 10] and exponential fading of the repair probability (see (d)), for μb = 3.886. (d) Adaptation probability for the optimal p from (c) (blue) and initial repair probability (orange). The dashed curve represents one example of delayed repair probability once the source of damage stops and the dash-dot curve represents the exponential fading envelope.
