Question: Minimize f ( x , y ) = x 2 + x + 2 y 2 + 0 . 2 5 using Powell method. Use

Minimize f(x,y)=x2+x+2y2+0.25 using Powell method. Use x1=(-1,-1)T as a starting point. The stopping criteria =0.001. Conduct one iteration only. Tabulate the ten values (from A to J in the allowed formulas sheets). These values are f(x1),1,x2(cdots,cdots)T,2,x3(cdots,cdots)T,3,f,xTx.
