| Mar 10, 2018 at 20:29 | comment | added | oliver | @Kirill: I will try that. I thought there was an analytical way of looking at the problem, but as has been already mentioned by HBR, this is gonna be heavily dependent on the solver type. I am still in the middle of learning to apply sundials/kinsol to simple problems, but I think I will be able to test it this week. | |
| Mar 10, 2018 at 18:52 | comment | added | Kirill | I think you're right that it could make a difference (e.g., if it greatly improves the conditioning of the system), but since there's no good mathematical way of determining the number of iterations in advance, your best bet is to treat this as a purely empirical question and just test the two approaches experimentally. | |

| Mar 6, 2018 at 20:12 | comment | added | oliver | @Beni Bogosel: when you suggest experimentation, do you think that any result, regardless of whether it is in favor or against the hypothesis, could be generalized to an arbitrary system of equations? But after all we are talking about mathematics, aren't we. | |
| Mar 6, 2018 at 19:47 | comment | added | Beni Bogosel | Is this backed up by some numerical experiences? Did you really try to solve the above systems and the one with added variables worked better? | |
