Let $X$ be a curve of genus $g\geq 2$ over a number field $K$. If $\mathrm{rk} \,\mathrm{Jac}\, X$ is less than $g$ there is a $p$-adic method of bounding $\# X(K)$ due to Chabauty and Coleman (see http://www-math.mit.edu/~poonen/papers/chabauty.pdf).
Does this method givesgive an algorithm for computing $X(K)$ (say, their coordinates)?
I agree to assume BSD and finitness of Shafarevich-Tate group.
TryignTrying to transform their proof to an algorithm, I met the following bottlenecks. First, we need to compute $\log \overline{Jac(K)} $$\log \overline{\mathrm{Jac}(K)}$ (bar means $p$-adic closure) in order to obtain a $1$-form whose integral will vanish on rational points. which, which is weaker than computing $Jac(K)$$\mathrm{Jac}(K)$ but I still do not know any non-conjectural algrorithmsalgorithms.
Next, the proof requires choosing base points in each residue class and I do not know how to find them algorithmically. Maybe, a solution can be obtained by extendindgextending the base field to where it is easy to find a base point.
Finally, we nnedneed an arguement foargument for computing zeroes of $p$-adic analytic functions. There is an arguement aargument, à la Hensel lemmaHensel's lemma, for computing zeroes sign-by-sign, which probably terminates if we search for points over number fields, but I am not sure.
