Comparison of the decoding performance of cold and warm-start
decoding for the $\llbracket 144,12,12 \rrbracket$ \ac{bb}

Decoding was performed using the \ac{bpgd} algorithm with
$T=1$.
The number of iterations refers to the outer \ac{bpgd}
iterations, i.e., the number of decimations.
The information used for the warm-start intialization
included only the messages on the Tanner graph.
$12$ rounds of syndrome extraction were performed and
standard circuit-based depolarizing noise was chosen as the noise model.
The physical error probabilty was fixed to $0.0025$.
