An algorithm is presented in ALGOL 60 which automatizes the heuristical work of an investigator determining graphically properties of sums of exponential functions. The algorithm processes a set of experimental points so that it approximates them by a sum of positive decreasing exponential functions. It determines not only the parameters of them (i.e. both the coefficients in the exponents and the multiplicative ones which form the linear combination) but also the number of exponential functions, which is in a certain sense optimal with regard to the dispersion of the input values.
