 This paper presents one algorithm for choosing optimal solution from a bivariant time series database. The presented algorithm uses a similarity measure to compare each object in the database to a specific suitable object. The proposed method is useful when dealing with multidimensional time series data, e.g., bi-variant time series, where c...
