The Steepest Descent Algorithm for Unconstrained ...
Using the steepest descent algorithm to minimize f (x) starting from x1 =(x1 1 1,x2)=(0, 10), and using a tolerance of =10−6, we compute the iterates shown in Table 2 and in Figure 2: For a convex quadratic function f (x)= 1xT Qx−cT x, the contours of the 2 function values will be shaped like ellipsoids, and the gradient vector ∇f (x)

The function logit−1(x)= ex 1+ex transforms continuous values to the range (0,1), which is necessary, since probabilities must be between 0 and 1.
