Letters to the Editor According to our procedure, the functional relation, mixing condition and objective function are rewritten as x1.1 = fib,o; Wl) x1.0 = Q1Cl.f + Bx1.1; ct+p=1 x2.1 = x2.0 + -; (x1,1 -x1.0) -C(WI) xa,o = 0 For this case, equations (1) through (4) reduce to n z1.0 = Zl.1 afi(xl.0; Wl) + 2% mQ,o; wd _ 1 (6) ax1,o a axl,O I z&o = za.1 (7) z1.1 = 8Zl.O (8) zz.1 = 1 (9) The maximum condition, represented by equation (S), becomes ~~,~fi(~~.~; wl) + $~xI.o; WI) -x1.01 -&I) = max.

If the maximum lies at the stationary place, equation ( 10) is equivalent to
