| possible to have an exponential and a polynomial together? |
| |
| The first assignment constructs "a -> {2, *, 3}_1", |
| while the second adds 5 as a polynomial function. |
| |
| The following two representations are not correct: |
| "a -> {{2, *, 3}_1, +, 5}_1" |
| "a -> {{2, +, 5}_1, *, 3}_1" |
| |
| The right solution is: |
| "a -> {2, *, 3}_1 + {0, +, 5}_1" |
| but this exposes yet again the "exp + poly" problem: the representation |
| is not homogen. Going into a Taylor decomposition could solve this problem. |
| |
| This is too difficult for the moment, and does not happen often. |
