Steepest Descent
1- We need starting solution x^t. Zeroise the iteration which is t. Specify tolerance value as ε. 2- at x^t point calculate g^t gradient and ||g^t|| then if ||g^t|| <= ε stop it, else continue. 3- Specfify road direction as d^t = -g^t. 4- Calculate f(x^t + a^td^t) as like a^t (step size) is minimum. 5- Calculate new solution point based on: x^(t+1) = x^t + a^td^t. 6- Increase iteration counter by 1 and go to 2.step.
