MullerSolver() and other Univariate solvers (NewtonSolver, SecantSolver) have had their no argument constructor deprecated. In the deprecation comment it says "to be removed in 3.0". I can see no mention in the javadocs for commons-math 2.2 or 3.0 of any replacement mechanism for constructing, and the method still exists in the 3.0 javadoc. I can think of 4 possibilities:
1) The deprecation of this method was a mistake and added at the same time as the constructor which took a function. 2) The proposal is that construction be moved to a factory class, but the Factory class has not been added yet. 3) There is an alternative way of constructing a MullerSolver I haven't found yet. 4) Deprecation has been decided with no migration route yet decided upon. Can anyone tell me which of these is correct, or a fifth option, and tell me how code which uses "new MullerSolver()" should be changed? I really hope it isn't 4! My guess is 2, as SecantSolver has UnivariateRealSolverFactoryImpl.newSecantColver(). While I might disagree with this design (force the use of the Factory) at least there is the hope of migration.
