Before revision:  This didactic text provides a brief review of some of the approaches that have been used to characterize complexity, and also suggests a possible definition of complexity based on the cost assigned to mapping the entity of interest, as well as on the  cost of the error implied by its respective reconstruction .
After revision:  This didactic text provides a brief review of some of the approaches that have been used to characterize complexity, and also suggests a possible definition of complexity based on the cost assigned to mapping the entity of interest, as well as on the several facets of complexity. More specifically, it is poised that complexity, an inherently relative and subjective concept, can be summarized as the cost of the error implied by its respective reconstruction .
