Ground states of three-dimensional Edwards-Anderson +J Ising spin glasses were calculated with a hybrid of genetic algorithm and local optimization. The algorithm was fast and reliable enough to allow extensive calculations for systems of linear size between 3 and 14 and determination of the average

The bond-random (-tJ) Ising model in the square lattice is considered in the square cluster approximation. The boundary between the ferromagnetic and spin-glass states at T = 0 is obtained as the transition point from the asymmetric distribution of the effective fields to the symmetric distribution.
## Abstract A family of methods aiming at the reconstruction of a putative fascicle map from any diffusionβweighted dataset is proposed. This fascicle map is defined as a tradeβoff between local information on voxel microstructure provided by diffusion data and __a priori__ information on the low c
