  Computations and Optimal Bang--Bang Control, Descrição: The algorithms used in solving bang-bang control problems were extended during the time of the project. The Switching time Computations (STC) code was reformulated using a Newton-style solution algorithm, with a number of features to accelerate convergence. Initial steps were taken in developing an approach for a multiple shooting version of STC, in the interests of more robust performance for poor initial guesses. An algorithm was developed for multiple input bang-bang control, based upon some elegant geometrical arguments. An algorithm was developed to use a Lagrange multiplier approach combined with STC to form a time optimal bang-bang control solution, called LTOS, a different approach to that previously implemented as TOS. Progress have been made in connection to the Two-Point Boundary-Value Problems arising from the well-known Pontryagin Maximum Principle. With a newly developed scheme it will be possible to relate the costates of the optimal control problem and the scalar multipliers of the Lagrangian formulation. Computer Implementation: During the time of the project, the STC code was initially programmed in Matlab. Further developments have led to code for the positive switching times as well as code for LTOS, the most substantial piece of code successfully developed during this project. . , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (0) / Especialização: (0) / Mestrado acadêmico: (0) / Mestrado profissional: (0) / Doutorado: (0) . , Integrantes: Cumhur Yalcin Kaya - Coordenador / S T Simakov - Integrante / Lucas S K - Integrante., Financiador(es): Australian Research Council - Remuneração., Número de produções C, T & A: 2

  Dynamic Modelling of Drug User Populations, Descrição: A class of models is introduced for the heroin epidemic in Australia, for the period spanning between 1986 and 1997. The models are reduced to two representative models. Using the latter models the so-called direct budget strategies are calculated over the period of concern for two `desired' time histories for the number of users. Optimal budget strategies are also derived, minimizing a trade-off function of the number of users and the budget. Comparisons and interpretations of these findings are included.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (0) / Especialização: (0) / Mestrado acadêmico: (0) / Mestrado profissional: (0) / Doutorado: (1) . , Integrantes: Cumhur Yalcin Kaya - Coordenador / Manju Agrawal - Integrante / Jerzy Filar - Integrante., Financiador(es): Drug And Alcohol Services Council South Australia - Bolsa., Número de produções C, T & A: 1
