Abstract
In this paper, we apply the equation discovery system to inverse analysis, and present the method of deriving the formula which can calculate unknown parameter directly. This method is the modification of RF5, and numerical model identification system using genetic algorithm and information criterion. It is assumed that the model is expressed with multidimensional polynomial equation. The number of terms and dimensions are coded into genetic algorithm. The coefficients for each model are obtained by least square method. The fitness for each chromosome is evaluated with an information criterion c-AIC. Numerical simulations are performed to demonstrate the validity and usefulness of this method.
