Hi(adsbygoogle = window.adsbygoogle || []).push({});

i am finding difficulty in minimzing the following in mathematica.

Can someone try it out and share with me the results.

Its urgent.

Its a constrained minimization problem in 8 variables c2,c3....c9

Can it be tried out in matlab or maple?

NMinimize[{1.383` c2^2 + 1.377` c3^2 + 1.2618` c4^2 + 1.36` c5^2 +

1.357` c6^2 + 1.29` c7^2 + 1.35` c8^2 + 1.349` c9^2 +

2 (-0.016892` c2 c3 - 0.02962` c3 c4 - 0.01903` c3 c5 -

0.03682` c4 c5 - 0.0170` c4 c6 - 0.03789` c5 c6 +

0.0107` c3 c7 - 0.02034` c5 c7 - 0.05074` c6 c7 +

0.01112` c3 c8 + 0.01282` c4 c8 - 0.0299` c6 c8 -

0.05788` c7 c8 - 0.0275` c7 c9 - 0.0588` c8 c9),

466 < c2 < 2059, 272 < c3 < 893, 171 < c4 < 475,

116 < c5 < 288, 83 < c6 < 191, 63 < c7 < 135, 49 < c8 < 101,

40 < c9 < 78}, {c2, c3, c4, c5, c6, c7, c8, c9}]
