Consider the feature model of Figure 1. For brevity, the feature names are abbreviated

(adv: advanced robot, sim: simple robot, sav: save data, ram: ramming).

List all valid combinatorial pairs of features (valid 2-wise sets).

Is the following sample a 2-wise covering array? (1 = true, 0 = false)

If not, add further configurations such that all pairs are covered.

How would you need to adjust the sample if one more mandatory feature (child feature under the root feature)

is added to the feature model?
