Q2. what is the solution to the problem?
Since multiplying (5a) by r and using (3c), from (5) the authors have: u2 (fr 2 - 2dr + e) = p-r , from which the authors gain that u2 = (p-r)/( fr 2 - 2dr + e) (7a) and u1 = r(r-p)/( fr 2 - 2dr + e). (7b) As in (4) the value of variables x depends on only the Lagrange variables u1 and u2, (7) gives the solution.
Q3. What is the purpose of this paper?
To analyze (2), let us suppose that for a given p, with y=0, the authors know the optimal status of the variables satisfying the Kuhn-Tucker conditions, and p is in an open interval where the value of every variable belonging to a set, let us call this set M, is positive, while the value of the variables not in M is zero at this interval.
Q4. What is the kink in the r-value?
Taking the crucial second iteration when M2 = {2, 3} (M1 = {3}), the problem can be structured in the following way: N2 = {1}, a2 =[1], and 1+ε 2 V11 = , a1 = [3, 4], V21 = [0, 0].
