Christa Fest,Karl-Julius Schmidtnalogue of Muchnik’s conditional complexity theorem. I.e., for all . and . there exists a program . of least possible length that transforms . to . and is simple conditional on .. Here all programs work in polynomial space and all complexities are measured with logarithmic accuracy instead of polylogarithmic one in the previous work.

A. Patchornik,M. Fridkin,E. Katchalskimples where the latter parameter is bounded whereas the former is not. As main result we show that permanents of matrices of bounded triangular tree-width are efficiently computable. This result holds as well for the Hamiltonian Cycle problem.

The Equivalence of Sampling and Searching, version. What makes this nontrivial is that the same .. works for every ...As an application, we prove the surprising result that . = ... = .. In other words, classical computers can efficiently sample the output distribution of every quantum circuit, if and only if they can efficiently solve every search problem that quantum computers can solve.
