A general purpose nonlinear curve fitting program for the British Broadcasting Corporation Microcomputer
Department of Biochemistry, University of Liverpool PO Box 147, Liverpool L69 3BX, UK
Software for nonlinear curve fitting has been written in BASIC to execute on the British Broadcasting Corporation Microcomputer. The program uses the direct search algorithm Patternsearch, a robust algorithm that has the additional advantage of needing specification of the Junction without inclusion of the partial derivatives. Although less efficient than gradient methods, the program can be readily configured to solve lowdimensional optimization problems that are normally encountered in life sciences. In writing the software, emphasis has been placed upon the user interface and making the most efficient use of the facilities provided by the minimal configuration of this system.
