I disagee with @RogerK - sentence #1 is best:
It is believed to still be efficiently solvable.
First, it's 100% correct. No problem there. Second, it avoids the "be still" combo in the other sentence. And that's a little weird sounding, to be honest. All those b's one after another, and the expression "be still" is a thing too, so the reader needs to unconsciously disambiguate.
Regardless, I'd do whatever I could to substitute that passive voice "It is believed..." for active voice: Who believes this? In a weak research paper, passive voice is often used to cover up a lack of research...
