We study the extension (introduced as BT in [5]) of the theory S 2 by instances of the dual (onto) weak pigeonhole principle for p-time functions, dWPHP(PV )x2 . We propose a natural framework for formalization of randomized algorithms in bounded arithmetic, and use it to provide a strengthening of Wilkie’s witnessing theorem for S 2+dWPHP(PV ). We construct a propositional proof system WF (bas...
