The expected number of candidates for secondary and 1-structures from an random input with a simplified arc-based energy model,${\overline{\mathbb{E}}}_{\mathbf{0}}\mathbf{\left(}\mathbf{n}\right)$and${\overline{\mathbb{E}}}_{\mathbf{1}}\mathbf{\left(}\mathbf{n}\mathbf{\right)}$: we compute the expected number of candidates obtained by folding 100 random sequences for secondary structures (A)(solid) and 1-structures (B)(solid). We also display the theoretical expectations implied by Theorem 3 (A)(dashed) and (B)(dashed).
