arXiv:2611.09174v1 Announce Type: new Abstract: This paper compares various Rosenbrock and Rosenbrock W-methods. To achieve this, some methods implemented in the Julia package OrdinaryDiffEqRosenbrock.jl are selected and benchmarked using test examples. The test examples include stiff ODE problems as well as differential-algebraic equations. In addition to the already known methods, the new W-method Rodas4PW is introduced and included in the tests.
