,Graphs of Bounded Treewidth Can Be Canonized in ,,ree canonization algorithm [22]. We define recursively what we call a . which gives with respect to some parameters in a logarithmic number of levels a canonical invariant together with an arrangement of all vertices. From this we compute a canonical labeling.

An Extended Tree-Width Notion for Directed Graphs Related to the Computation of Permanents,mples 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.

Our algorithm extends to superconstant but low degree polynomials and still runs in quasipolynomial time.

In this paper, we use tools from Kolmogorov complexity to show that sampling and search problems are “essentially equivalent.” More precisely, for any sampling problem ., there exis
