  • The fraction of frustrated triplets for all networks at two different bin widths. A frustrated triplet consists of three neurons or electrodes with conflicting interaction strengths Jij. These conflicts prevent any state of the triplet from achieving harmony. Note that frustration is common in most preparations, suggesting that it is difficult for networks to settle into states with long-term stability.
