摘要

In this paper, the Feddeev-Jackiw approach is improved by the Wu elimination method, so a great many complicated computations in solving constraints for the finite-dimensional polynomial-type constrained dynamics can be executed easily byby using computers. Moreover, based on the Faddeev-Jackiw approach, a new algorithm of solving the constrained dynamics is presented. The new algorithm is simpler and stricter than the Faddeev-Jackiw approac.Using the new algorithm, the second Cawley counterexample is solved.
