The abstract class QuantLib::Solver1D provides the interface for one-dimensional solvers which can find the zeroes of a given function.
A number of such solvers is contained in the ql/Solvers1D directory.
The implementation of the algorithms was inspired by "Numerical Recipes in C", 2nd edition, Press, Teukolsky, Vetterling, Flannery - Chapter 9
Some work is needed to resolve the ambiguity of the root finding accuracy definition: for some algorithms it is the x-accuracy, for others it is f(x)-accuracy.
