Comparison of Integer Programming (IP) Solvers for Automated Test Assembly (ATA). Research Report. ETS RR-15-05
Donoghue, John R.
ETS Research Report Series, Jun 2015
At the heart of van der Linden's approach to automated test assembly (ATA) is a linear programming/integer programming (LP/IP) problem. A variety of IP solvers are available, ranging in cost from free to hundreds of thousands of dollars. In this paper, I compare several approaches to solving the underlying IP problem. These approaches range from traditional computer programming, through LP/IP-specific modeling languages, to plug-ins for common software such as Excel. The features of several of the major IP solvers are briefly reviewed, describing which of the features are more or less useful in the context of ATA. The appendices include a list of resources that I have found particularly useful. Appended are: (1) Additional Resources; and (2) Kinds of Software Licenses.
