Line Plot from Scientific Research

How the optimal absolute and rank-based aspiration changes with q for (i) a standard normal distribution; (ii) a gamma distribution; (iii) a Student's t-distribution with 1.5 degrees of freedom; (iv) a beta distribution with alpha=5, beta=1; and (v) a beta distribution with alpha=1, beta=5. See Online Appendix F for how the optimal values of w and c were computed. Note that optimal average-based aspiration is not displayed; it is always 1, regardless of performance distribution or q.
