A new convection-diffusion global minimization method for solving inverse problems of chemical kinetics
Engineering Education # 04, April 2013 DOI: 10.7463/0413.0569246 A new deterministic global minimization method based on the numerical solution of the convection-diffusion boundary problem was developed. With the help of this method, the inverse problem of chemical kinetics was solved. Problems of identification of speed constants in chemical reactions are usually based on minimization of functions. In most cases it is necessary to deal with "stiff" systems of differential equations and, respectively, with many objective functions with ravine surface and local extremums, which makes application of existing multidimensional minimization methods complicated. Two main conceptions are included in this method: diffuse overcoming of local extremums and transforming multivariable minimization to one-dimensional minimization.
