• IIUC, this PR doesn’t provide a general solution to address Improve change_parameters.py #311. What we need is support for a setup like (a, b, c) = [(1, 2, 3), (4, 5, 6)], where a, b, c are arbitrary runtime options and the script should execute just two cases: (a, b, c) = (1, 2, 3) and (a, b, c) = (4, 5, 6).
• Please clarify, presumably in the header, which test problem can be used to validate the default parameters defined in this script (perhaps Plummer?).
