Multifario

¡A C library for finding solutions to nonlinear systems of equations with a small number of parameters.

¡Uses user-supplied domain specific solver, to which Multifario presents a sequence of problems at carefully chosen parameter values.

¡The resulting set of solutions covers the solution manifold in a specific part of parameter space.

¡Interfaces to LOCA and AUTO packages

¡Reference implementation of published algorithm

	1. The main groups using multifario are Sandia, where they are looking at parameterized circuits (they have something called Xyce, which is like SPICE). They helped do the interface between LOCA and multifario, but it sits in the LOCA code, so I don't know if that counts.
	2.The other group is John Maddocks at EPFL in Lausanne Switzerland who does DNA folding. A former postdoc of his, Sebastien Neukirch used multifario to study a uniform elastic rod, and John has plans to use EPFL's new BlueGene for more complicated models and we have plans to parallelize multifario for that.” - MH
