16. Our results are obtained for one particular random Jij} configuration for the quenched disorder, the same as that used in Ref. 6. Simulations using different configurations confirm that our conclusions are not affected by the choice of Jij}.

18. The exponent x also takes on a range of values between 0 and 0.5. However, we restrict our attention to τ and β in this work since the stretched exponential character of Eq. (1) is of widest interest.

22. The results reported here using τi0 are qualitatively unchanged if we use instead the values of τ obtained from fitting the qi(t) curves to Eq. (1).
23. Note that the flip rate νi evaluated in Ref. 6 characterizes the short-time behavior of qi(t). Specifically, νi=[1-qi(1)]/2.
24. An elementary plaquette of a square or simple cubic lattice is termed unfrustrated (frustrated) if the product of the Jij values for the four edges of the plaquette is +1 (-1). We define an unfrustrated (frustrated) site as a site for which all of the neighboring elementary plaquettes are unfrustrated (frustrated).
25. εi is defined as the time average of -∑jsiJijsj, where j labels the nearest-neighbor sites of i; see Ref. 6.
