Finite-termination conjecture. For $A\notin{\mathcal{CP}}^n$, Procedure with a suitable pivot rule in Step2(b) ends after finitely many iterations with a separating witness $W$.

Let $A$ be a real completely positive matrix of order $n$, meaning that $A=BB^{T}$ for some nonnegative real matrix $B$. The CP-rank of $A$, denoted by…
