 This package computes optimal stability functions for Runge-Kutta methods.
 Here optimal means that the stable step size is maximized for a given ODE
 spectrum.  The corresponding optimization problem is intractable under a
-direct implementation.  The package uses the algorithm developed by
-@2012_optimal_stability_polynomials, which transforms the problem into a
+direct implementation.  The package uses the algorithm developed in
+[@2012_optimal_stability_polynomials], which transforms the problem into a
 sequence of convex problems and typically yields a solution in a few seconds or
 less.  This package is usually used as the first step in designing a
 Runge-Kutta method.
