Interferometric SAR phase unwrapping by parallel tempering on a APE100/Quadrics supercomputer

A stochastic algorithm for solving the Phase Unwrapping (PU) problem has been implemented on a APE100/Quadrics SIMD architecture. PU is formulated as a constrained optimization problem for a vector field of integers and it is solved by the Parallel Tempering tecnique, which allows an efficient implementation on the APE100 architecture.
