          <datacite:description descriptionType="Other">An improved preconditioned BiCGStab algorithm (improved PBiCGStab) is proposed. Rational preconditioned algorithm of CGS has been constructed, by applying the derivation procedure of the CGS to the preconditioned BiCG. In order to extend this approach to the BiCGStab, minimum residual part of the BiCGStab must be considered logically. This proposed algorithm is also more rational than the conventional typical PBiCGStab mathematically. Numerical results show advantages of this improved PBiCGStab.</datacite:description>
