$3$-$\mathrm{Partition}$ problem is $\mathsf{NP}$-Complete in a strong sense meaning there is no pseudo-polynomial time algorithm for it unless $\mathsf{P=NP}$. I am looking for the fastest known exact algorithm that solves $3$-$\mathrm{Partition}$.

Is there a fast (e.g subexponential) algorithm for $3$-$\mathrm{Partition}$? Is it possible to solve it faster than using SAT solvers?

If you find a fast (sub-exponential) exact algorithm for 3-Partition , while 3-Partition is NP-Complete, then dear sir you have just proven P=NP, which no body has done so far, and you have a 1M $ price waiting for you as well as wealth and fame, cheers.

Anyway if you do have a faster than a SAT solver, wouldn't you actually be performing SAT it's self faster? I mean if you can reduce SAT to 3-PARTITION and you can solve 3-PARTITION in sub-expo time, doesn't that mean that SAT can be solved in sub-expo time, hence all NP-COMPLETE problems also can be solved in such time? So you might as well be looking for a sub-expo time solution of any other NP-COMPLETE problem just as well, it would still be a significant breakthrough.
