Probability curves obtained in Experiment 1. The four curves denote _{P T} (^x(1)=^x∗;A,N)with |T|=|^{T true} + _{Δ e} |=2, ${\mathbf{P}}_{\mathbf{T}\cup \left\{i_r\right\}}^{}({\mathbf{x}}^{\left(1\right)}={\mathbf{x}}^{\ast };\mathbf{A},\mathbf{N})$, the probability that add an index _{i r} of nonzero entries into set T, i.e, |^T″|=|T∪{ _{i r} }|=|(^{T true} + 1) + _{Δ e} |=3, ${\mathbf{P}}_{\mathbf{T}\cup \left\{i_e\right\}}({\mathbf{x}}^{\left(1\right)}={\mathbf{x}}^{\ast };A,N)$, the probability that add an index _{i e} of zero entries into set T, i.e, |^T″|=|T∪{ _{i e} }|=|^{T true} + ( _{Δ e} + 1)|=3 and ${\mathbf{P}}_{\mathbf{T}\cup \left\{i_r\right\}}({\mathbf{x}}^{\left(1\right)}={\mathbf{x}}^{‡};\mathbf{A},\mathbf{N}\setminus \{i_r\left\}\right)$.
