METHOD AND/OR SYSTEM FOR TRANSFORMING BETWEEN TREES AND STRINGS

Briefly, in accordance with one embodiment, a method of processing non-transitory stored binary digital signal quantities using a computing device is disclosed. For example, a computing device transforms between at least first and at least second non-transitory stored binary digital signal quantities respectively representing at least a first and at least a second expression. The represented expressions have a common view for non-common expression types of the represented expressions and have a non-common view for common expression types of the represented expressions. The represented expressions include at least one of the following expression types: a hierarchical edge and/or node labeled tree or a symbol string.
