java - Finding optima of PolynomialFunction in commons.math -
is there simple way find optimum of polynomialfunction (which univariatedifferentiablefunction) in commons.math? there bewildering array of multidimensional optimizers, afaics explicitly univariate optimizer brent, doesn't take advantage of differentiability.
polynomials special functions (in general sense of "special") , have lots of distinctive, useful properties. advice exploit properties instead of trying use method more general functions. specifically, extreme values of polynomial roots of derivative (where second derivative nonzero). derivatives of polynomial easy construct , evaluate, in java. see apache commons math has laguerresolver find roots of polynomial.
