A New Converge Method on Active Progression

This paper discusses the similarity and difference between ratio value and square root value converging method. It Explains that the latter one applies to a more wide range of fields than the former one by means of problems and examples and then it combines the two forms of converging method, thus puts forth a more generally accepted active progression converging method.
