Run Test Assembly

Description

runAssembly is a function to perform test assembly. This function is used internally in Static and Shadow.

Usage

runAssembly(config, constraints, xdata = NULL, objective = NULL)

Arguments

config	a config_Static or a config_Shadow object containing configuration options. Use createStaticTestConfig and createShadowTestConfig for this.
constraints	a constraints object. Use loadConstraints for this.
xdata	a list containing extra constraints in MIP form, to force-include previously administered items.
objective	the information value for each item in the pool.

Value

a list containing the following entries:

• MIP a list containing the result from MIP solver.

• status the MIP status value, indicating whether an optimal solution was found.

• shadow_test the attributes of the selected items.

• obj_value the objective value of the solution.

• solve_time the elapsed time in running the solver.
