The overall algorithm for solving (4.1) is to (i) compute the recurrence coefficients associated with [[mu].sub.n] in (4.5) via quadratic measure modifications, (ii) compute order-N [[mu].sub.n]-Gaussian quadrature nodes and weights [z.sub.j,N] and [v.sub.j,N], respectively, (iii) identify m such that (4.3) holds so that x+ may be computed in (4.4), and (iv) iteratively apply the bisection algorithm with the initial interval defined by x+ using the evaluation procedures for [F.sub.n] outlined in Section 3.

Compute B and [lambda], [F.sup.(n)] [left arrow] [F.sub.opt] and [Q.sup.(n).sub.1] [left arrow] [Q.sub.1,opt], [Q.sup.(n).sub.2] [left arrow] [Q.sub.2,opt] [lambda] should be chosen from bisection algorithm and satisfied with [mathematical expression not reproducible] could be obtained by substituting [lambda] into (30), and then [[LAMBDA].sup.2.sub.F], F, [Q.sub.1], and [Q.sub.2] will be gotten as follows.
Use bisection algorithm to determine corrected maximal [[??].sub.[DELTA]] with tolerance of 0.0001.
As an example, steps of this bisection algorithm to optimize [gamma] include the following.
Again, the solution to the problem (17a)-(17c) can be obtained by using a standard bisection algorithm.
compute [sup.t+[DELTA]t][[bar.[sigma]].sup.(k)]; here, one step of a bisection algorithm is used; if [sup.t+[DELTA]t][[bar.[sigma]].sup.(k)] does not represent (to a specified tolerance) the solution, go to (2),
Then, given [P.sub.S] at S and considering the constraint [T.sub.R], the optimal [P.sup.o.sub.R] at R can be achieved by the bisection algorithm, which will be described in the subalgorithm of Algorithm 1.
In Theorem 3.1, which is used in the following to find the number v([lambda]), formula (3.10) requires one multiplication less for the semiseparable case, and this is why the bisection algorithm works 10% faster than for quasiseparable matrices.
