Municipal Bond Bidding and underwriting - Net Interest Cost

The borrower has specified how much it wants to pay back in face value in each of a number of future maturity years.
The bond underwriter wants to choose an interest rate(or coupon payment) for each maturity given that

a) borrower has restricted number of distinct interest rates allowed,
b) underwriter knows the market price at which it can resell a bond of a given maturity and interest rate,

and so as to strike a good compromise between the two objectives:
i) underwriter makes a reasonable profit on the resale,
ii) the bid is attractive to the borrower in terms of low interest rates and amount of money he receives initially.

This model puts a constraint on (i) and makes it attractive to the borrower by minimizing the total interest payments (the so-called Net Interest Cost) of the cash stream as seen by the borrower. The underwriter pays the borrower the face value of the bonds, plus perhaps a premium;
