- W1483148630 abstract "Abstract A simplicial complex is d-collapsible if it can be reduced to an empty complex by repeatedly removing (collapsing) a face of dimension at most d − 1 that is contained in a unique maximal face. We prove that the algorithmic question whether a given simplicial complex is d-collapsible is NP-complete for d ⩾ 4 and polynomial time solvable for d ⩽ 2 . As an intermediate step, we prove that d-collapsibility can be recognized by the greedy algorithm for d ⩽ 2 , but the greedy algorithm does not work for d ⩾ 3 ." @default.
