The following (mutation) code can be remove from coin-grinder [here](https://github.com/bitcoin/bitcoin/blob/1444ed855f438f1270104fca259ce61b99ed5cdb/src/wallet/coinselection.cpp#L466) without encountering a test failure ``` if (curr_try >= TOTAL_TRIES) { // Solution is not guaranteed to be optimal if `curr_try` hit TOTAL_TRIES result.SetAlgoCompleted(false); break; } ``` This ought to be a similar test to [Test BnB attempt limit (`TOTAL_TRIES`)](https://github.com/bitcoin/bitcoin/blob/1444ed855f438f1270104fca259ce61b99ed5cdb/src/wallet/test/coinselection_tests.cpp#L166)
