Abstract
Methods of determining the phases for noisy and incomplete surface dif fraction data (X-ray or transmission electron) are investigated. It is found that, while conventional methods do not always work, a minimum- entropy method that uses the relative entropy is more effective in fin ding the correct solutions.
