\(a = \sum _n = 1^Ny^n\underline{f}^n\)

\(a = \sum _n = 1^Ny^n\underline{f}^n\)

\(b = \sum _n = 1^N\underline{f}^n\)

\(b = \sum _n = 1^N\underline{f}^n\)

L = 0

R = N

Step 2

Compute

Compute

\(L = L + 1\)

\(a = a + y^R\left( \overline{f}^R - \underline{f}^R \right)\)

\(a = a + y^L\left( \overline{f}^L - \underline{f}^L \right)\)

\(b = b + \overline{f}^R - \,{\underline{f}}^R\)

\(b = b + \overline{f}^L - \underline{f}^L\)

\(y_r = \frac{a}{b}\)

\(y_l = \frac{a}{b}\))

\(R\ = \ R\ - \ 1\)

Step 3

If \(y_l \le y^L + 1\), stop;

If \(y_r \ge y^R\), stop;

Otherwise, return to Step 2.

Otherwise, return to Step 2.
