Ticket #3995 – Description
initial v1 1 1 This is a part of #3944. 2 2 3 Brent does currently not detect if the residual corresponding to 4 the initial guess (or previously converged solution) is below 5 the tolerance, before going into the bracketing step. As a consequence, 6 Brent takes one or two bracketing steps to bracket the root and then 7 a couple of convergence steps to find the solution. 3 Brent does currently not detect if the residual corresponding to the initial guess (or previously converged solution) is below the tolerance, before going into the bracketing step. As a consequence, Brent takes one or two bracketing steps to bracket the root and then a couple of convergence steps to find the solution. 8 4 9 A check to detect the case when the residual corresponding the 10 initial guess should be added, in which case the algorithm 11 returns successfully. 5 A check to detect the case when the residual corresponding the initial guess should be added, in which case the algorithm returns successfully.
