Dirk R. De Buyser
Parameter Estimation - Coupled Ordinary Differential Equations
based on D.R. De Buyser and J.A. Spriet, K.U.Leuven, OPTISIM: an Optimization-Simulation Environment for Model Building. In: Simulation Environments and Symbol and Number Processing on Multi and Array Processors, R.C.Huntsinger et al.(eds), SCSI, San Diego,CA,16-21,1988. Extented to maximum 10 independent variables, 100 coupled differential equations with real and complex expressions (Complex number = Re + i.Im = [Re,Im]), maximum 100 parameters, real and complex matrices, variable step and semi-stiff integration, Nelder-Mead (non-constrained and constrained) and machine-learning pattern-search (Hooke-Jeeves) optimization, parameter estimation (absolute or relative) of multiple data-sets, maximum 100 2-Dimensional, 3-Dimensional real and complex data plots (visibility is used for imaginary part of complex numbers). Developed in Java-Android. Calculations in back-ground while other applications may run.
