I have a system of equations that Mathematica 3.0 bogs down on for most problems of interest. I would like to seed a solution that is found for one set of parameters into the routine for finding the solution of a "nearby" problem (meaning one with only slightly different parameter values). How can I do this? I have tried including a set of conditions (bounds) on the solution space as inequalities in the system of equations to be solved, but Mathematica gagged on the form of the inequalities. Are there other methods of launching Solve[] from an initial trial solution? Should I be trying to learn how to instruct Solve[] on what methods it should be using? If so, where can I learn about this? Examples that illustrate any explanation would be especially helpful. Thanks. Bill Christens-Barry
