Optimal Control of Mathematical Models for Antiangiogenic Treatments

2015
In the models considered so far, the focus was on the cancerous cells progressing from mathematical models for homogeneous tumor populations of chemotherapeutically sensitive cells to heterogeneous structures of cell populations with varying sensitivities or even resistance. From an optimal control point of view, optimal treatment schedules change from

Comment on 'Optimal control via mathematical programming'

Journal of Guidance, Control, and Dynamics, 1982
Breakwell considers the slewing of a flexible spacecraft whose dynamics can be approximated by Eq. (2). In his conclusions, he discusses two problems encountered previously by the author in Refs. 2 and 3. These are: 1) The fact that the differential equation(s) are stiff and often subject to numerical difficulties if one employs eigenvalue routines or ...

On a class of optimal control problems in Mathematical Biology

IFAC Proceedings Volumes, 1999
Abstract A collection of experimental and empirical relations in the physiology of nutrition is organized as a control system describing the evolution of the proteins, of the lipids and of the total weight determined by inputs (control functions) represented by digestible crude proteins and by digestible energy.

Distributed-parameter optimal control via mathematical programming

Journal of the Franklin Institute, 1980
Abstract In this paper a variety of optimal control (OC) problems for distributed- parameter (DP) systems are approached using mathematical programming (MP). First, the principal DP models in current use are given, a variety of DP objective functions is provided, and the OC problems based on them are formulated.

Nonlinear Problems in Mathematical Programming and Optimal Control

2009
Necessary conditions of optimality are obtained for general mathematical programming problems on a product space. The cost functional is locally Lipschitz and the constraints are expressed as inclusion relations with unbounded linear operators and multivalued term.

Optimal control of ultradiffusion processes with application to mathematical finance

International Journal of Computer Mathematics, 2014
We introduce the optimal control problem associated with ultradiffusion processes as a stochastic differential equation constrained optimization of the expected system performance over the set of feasible trajectories. The associated Bellman function is characterized as the solution to a Hamilton–Jacobi equation evaluated along an optimal process.
