Change point analysis is a statistical tool that aims to attain homogeneity within time series data. This is accomplished through partitioning the time series into a number of contiguous homogeneous segments. The applications of such techniques range from identifying chromosome alterations to solar flare detection. In this manuscript we present a general purpose search algorithm called cp3o that can be used to identify change points in multivariate time series.
