runAssembly

Run Test Assembly

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

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

`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.

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.
