ABSTRACT:
An interior point cutting plane algorithm for solving Maximum Cut problems
of a particular structure is described. The problem of interest is
determining the ground states of two dimensional +J,-J Ising spin glasses
on square lattices with nearest neighbour interactions and periodic
boundary conditions. Computational results for grids of sizes up to
100 x 100 are presented. An estimate of the ground state energy
of an infinite
spin glass system with the proportion of negative bonds equal to 0.5
is given.
