Spreadsheet computing with Finite Domain Constraint Enhancements

Abstract: Spreadsheet computing is one of the more popular computing methodologies in today's modern society. The spreadsheet application's ease of use and usefulness has enabled non-programmers to perform programming-like tasks in a familiar setting modeled after the tabular "pen and paper" approach. However, spreadsheet applications are limited to bookkeeping-like tasks due to their single-direction data flow. This thesis demonstrates an extension of the spreadsheet computing paradigm in overcoming this limitation to solve constraint satisfaction problems. We present a framework seamlessly incorporating a finite constraint solver with the spreadsheet computing paradigm. This framework allows the individual cells in the spreadsheet to be attached to either a finite domain or a constraint specifying the relationship among the cells. The framework provides an interface for constraint solving and further enhances the spreadsheet computing paradigm by providing a set of spreadsheet-specific constraints that will aid in controlling the scalability of large spreadsheet applications implementations. Finally, we provide examples to demonstrate the usability and usefulness of the extended spreadsheet paradigm.
