“…The obtained protocols u and w, provide from the single-valued selection c θ by (9) to the set-valued map of regulation F θ by (6a), which should be strict on the subset D θ by (5c) : ∀(p, q, r, w) ∈ D θ , F θ (p, q, r, w) = ∅, and they rend the model (1) globally viable on the subset D θ , as it is demonstrated in the Proof 4 of the Lemma 1. The linear dynamics (1c) and (3) of the tumor repair r and the radiation control w respectively, allow to get the useful expression (7a) of the set-valued map of regulation F θ , as it is proved in the Proof 4 of the Lemma 3, and the single-valued selection c θ is a solution to the following problem of minimization : min ||(u, v)|| such that (u, v) ∈ [0, u max ] × [0, w max ] by (5a), and θ (p, q, r, w) + h(p, q, r, w), (u, v) ≤ 0 by (8), which is numerically approached by the method of Uzawa in the last Section 5, and implemented into the discretized model (11) by the method of Euler, to get the numerical simulations of Figure 2, which are in perfect conformity with the theoretical results of the preceding Section 4.…”
