Differentiating (2) with respect to kðtkÞðk 1⁄4 1;2; . . . ; pÞ;g1 and g2, and setting these partial derivatives equal to zero, the following set of equations is obtained.

Abstract

where kðtÞ 1⁄4 ðkðt1Þ; kðt2Þ; . . . ; kðtpÞÞ ;g1 and g2 are the Lagrange multipliers. Differentiating (2) with respect to kðtkÞðk 1⁄4 1;2; . . . ; pÞ;g1 and g2, and setting these partial derivatives equal to zero, the following set of equations is obtained: @LðkðtÞ;g1;g2Þ @kðtkÞ 1⁄4 2kðtkÞ 2g1ðp kÞ 2g2 1⁄4 0; ð3Þ @LðkðtÞ;g1;g2Þ @g1 1⁄4 2 Xp k1⁄41 ðp kÞkðtkÞ t ! 1⁄4 0; ð4Þ @LðkðtÞ;g1;g2Þ @g2 1⁄4 2 Xp k1⁄41 kðtkÞ 1 ! 1⁄4 0: ð5Þ
