  abstract =     "Given data in the form of a collection of (x,y) pairs
                 of real numbers, the symbolic function identification
                 problem is to find a functional model of the form y =
                 f(x) that fits the data. This paper describes a system
                 for solution of symbolic function identification
                 problems that combines a genetic algorithm and the
                 Levenberg-Marquardt nonlinear regression algorithm. The
                 genetic algorithm uses an expression-tree
                 representation rather than the more usual binary-string
                 representation. Experiments were run with data
                 generated using a wide variety of function models. The
                 system was able to find a function model that closely
                 approximated the data with a very high success rate.",

                 Symbolic regression but uses Levenberg-Marquadt
                 statistical technique to adjust parameters to get
                 closer (equivalent of local hill climbing?) Some case
