313--337

Skew-symmetrizable matrices play an essential role in the classification of cluster algebras. We prove that the problem of assigning a positive definite quasi-Cartan companion to a skew-symmetrizable matrix is in polynomial class P. We also present an algorithm to determine the finite type Δ ∈ { {𝔸n, 𝔻n, 𝔹n, ℂn, 𝔼6, 𝔼7, 𝔼8, 𝔽4, 𝔾2 } of a cluster algebra associated to the mutation-equivalence class of a connected skew-symmetrizable matrix B , if it has one.
