/ Risch's decision procedure for \
| integration, not surprisingly, uses a |
| recursion on the number and type of the |
| extensions from the rational functions |
| needed to represent the integrand. |
| Although the algorithm follows and |
| critically depends upon the appropriate |
| structure of the input, as in the case |
| of multivariate factorization, we |
| cannot claim that the algorithm is a |
| natural one. In fact, the creator of |
| differential algebra, Ritt, committed |
| suicide in the early 1950's, largely, |
| it is claimed, because few paid |
| attention to his work. Probably he |
| would have received more attention had |
| he obtained the algorithm as well. |
