The trackability limitation of current gradient algorithm is discussed.A new algorithm, named variable parameter gradient estimation algorithm with local polynomial approximation is proposed.
In this paper, the mathematical model of the reltion between water saturation vapor pressure and saturated temperature is established in the form of monoacidic polynomials.
According to the nature of two-dimensional biharmonic equations,this paper obtains a polynomial solution of the biharmonic equation for stress function by means of the MATHEMATICA software.
In this paper, we show that the Pseudo-Symmetric property of spherical point set can be characterized by the eigen values of eigenpolynomial and it has the closeness under the metric sum operation.
Each of the polynomials in our space will only have finitely many terms, but the full space is going to include polynomials with arbitrarily large degrees.
In general, since every individual polynomial has only finitely many terms, its coordinates will be some finite string of numbers with an infinite tale of zeroes.
