Abstract

Optimization techniques are applied to the bispectrum. The Levenberg-Marquardt algorithm for nonlinear least squares is used to determine the parameters of binary stars. The conjugate gradient and conjugate direction algorithms are used to estimate the full set of object phases and moduli. Simulated and observed data are utilized in each optimization.
