Currently two\nautomatic test assembly (ata) approaches are enabled. For\nexample, the weighted (positive) deviations method, wdm(),\nproposed by Swanson and Stocking (1993)\n was implemented in its full\nspecification allowing for both item selection as well as test\nform refinement. The linear constraint programming approach,\natalp(), uses the linear equation solver by Berkelaar et. al\n(2014) to enable a\nvariety of approaches to select items.", "License": "LGPL-2",
