Analytical gradients of all constraints are constructed and the problem solved numerically. The optimal treatment is low intensity therapy followed by high intensity therapy.

β¦ Synopsis
Cancer chemotherapy with application of one drug is studied. The negative and inhibiting e ect of the tumor on normal cells is taken into account. Under certain assumptions, we determine the optimal regimen that minimizes the tumor burden at the end of a ΓΏxed period of therapy while maintaining the normal cell population above a prescribed level.

This paper treats a quasi-optimal regulator which operates in two modes. The first mode is saturating sampled-data relay, whereas the second mode may be either continuous or discrete. A possible method of realizing the proposed control law by means of a special purpose analog computer is discussed.
