Phys. Rev. B 77, 214432 (2008) [9 pages]Reduction of dilute Ising spin glassesReceived 19 March 2008; revised 24 May 2008; published 25 June 2008 The recently proposed reduction method for diluted spin glasses is investigated in depth. In particular, the Edwards-Anderson model with ±J and Gaussian bond disorder on hypercubic lattices in d=2, 3, and 4 is studied for a range of bond dilutions. The results demonstrate the effectiveness of using bond dilution to elucidate low-temperature properties of Ising spin glasses and provide a starting point to enhance the methods used in reduction. Based on that, a greedy heuristic called “dominant bond reduction” is introduced and explored. © 2008 The American Physical Society URL:
