Hamilton-cycle reconstruction conjecture from induced subgraphs
Hamilton-cycle reconstruction conjecture from induced subgraphs
For a graph , let denote the multiset of its induced subgraphs on vertices. There are constants and such that, for every integer , the number of Hamilton cycles of every -vertex graph is uniquely determined by the multiset of induced subgraphs of on vertices.
Hamilton-cycle reconstruction conjecture. There are constants and such that, for all integers , the number of Hamilton cycles of an -vertex graph is uniquely determined from .
The conjecture proposes that Hamilton-cycle counts, despite involving connected spanning structures, can be reconstructed from induced subgraphs of a fixed linear-size fraction strictly smaller than the full graph. The supplied text gives no resolution, so the conjecture is treated as open.
