Abstract
The disclosure is generally directed to a method and computing device for maintaining dependencies among multiple reference elements (e.g., formulas of a table or spreadsheet). In various embodiments, prior to a reevaluation operation carried out on the reference elements, a computing device receives an input of a reference element via a user interface (e.g., receives a user's input of a formula), assigns the reference element to a group based on the dependency between the reference element and one or more other reference elements, and assigns the reference element to a location within a dependency graph to which the other reference elements are assigned. In response to an event that requires at least one of the reference elements to be reevaluated, the computing device reevaluates each group of reference elements in sequence a group at a time.
