SolverConfig-class

SolverConfig

An S4 Class to represent parameters of the MIP solver configuration.

As an advanced approach to computerized adaptive testing (CAT),
shadow testing (van der Linden(2005) <doi:10.1007/0-387-29054-0>) dynamically
assembles entire shadow tests as a part of
selecting items throughout the testing process.
Selecting items from shadow tests guarantees the compliance of all content
constraints defined by the blueprint. 'RSCAT' is an R package for the
shadow-test approach to CAT. The objective of
'RSCAT' is twofold: 1) Enhancing the effectiveness of shadow-test CAT simulation;
2) Contributing to the academic and scientific community for CAT research.
RSCAT is currently designed for dichotomous items based on the three-parameter logistic (3PL) model.
