Dear Mathgroup,
I do some optimization practice using FindMinimum command. The Objective
function is :
-k + 0.004*t*(93633.3333333333 + 529.9999999999999*t + t^2) +
(0.005000000000000001*(1.566333333333333*10^7*k - 93633.3333333333*k*t -
529.9999999999999*k*t^2 - 1.*k*t^3))/(0.75 + 1.*k)
But I could not get the solution for it. t and k are variables.
the message I got is :
FindMinimum::fmlim: The minimum could not be bracketed in 30 iterations.
The arguement is: FindMinimum[test3[t,k],{t,50,80},{k,2,5}]
I hope someone can help me out. Very appreciate.
