Breuer's grow factor algorithm in computer algebra
J. A. van Hulzen · 1981
Computer algebra can be of importance in solving electrical network synthesis problems. It enables to generate automatically FORTRAN-programs needed to solve the underlying systems of nonlinear multivariate polynomial equations. Such systems are obtained by equating the numerical target function and a symbolically computed equivalent. Breuer's grow factor algorithm is extended not only to eventually improve the result of required determinant calculations, but also to optimize FORTRAN-code describing the system and the associated Jacobian. It is indicated how this common subexpression search approach can be extended.
