Optimal Chain Density and Space-Time Tradeoffs for the TSP
The authors describe the tradeoff as nearly settled rather than settled.
algorithms-optimization / Extremal Set Theory, Algorithms
The paper nearly settles the tradeoff between the size of a set system over $[n]$ and its number of full chains, an extremal question raised by Johnson, Leader and Russell as a counterpart to Sperner-type results, and linked by recent work to the space and time complexity of Bellman–Held–Karp dynamic programming for permutation problems.
