On the Approximation of the Stretched Exponential Function

Coefficients of the best uniform approximation of f(x) = exp(-xb) by exponential sums Sn(x)=w1e-lambda1x + ... + wne-lambdanx :
Unconstrained: b = 0.50 / b = 0.68
With interpolation condition Sn(0)=1 : b = 0.30 / b = 0.50 / b = 0.60 / b = 0.68
With interpolation condition Sn(0)=1, b=0.1 ... 0.9 : n = 2 / n = 3 / n = 4 / n = 5 / n = 6
