Understanding the problem

Read the background

For every graphical degree sequence on n≥4 vertices, the lazy simple-undirected switch chain that proposes switches uniformly on four vertices has total-variation mixing time at distance 1/4 at most 2n⁸.

Why it matters

If correct, resolves the simple-undirected Kannan–Tetali–Vempala switch-chain conjecture with an explicit polynomial bound.

What counts as progress

Does the switch chain mix in polynomial time for every graphical degree sequence?
