“…The known constructions of the optimal sequence via analytic expressions were presented in the similar form as in Theorem 2 but, as we have mentioned above, only in the cases k = 1, 2, 3. For higher values of k, as well as for some other versions of this problem, the algorithms computing the probability of success and the elements of an optimal sequence can be found in various of papers (see [1,2,3,4,5,7,8,11,12,15]). However, in contrast to the analytic solution, these methods apply mechanisms via dynamic or linear programming, and hence only numerically allow to determine the elements of an optimal sequence.…”
