Ionic relaxation Steepest descent 1.initial guess 最速下降法 初始点 J6,0)。 2.calculate the gradient g( 3.make a step into the direction of the steepest descent 2=-1/Tmax(B)g() 最小值 4.repeat step 2 and 3 until convergence is reached for functions with long steep valleys convergence can be very slow max minIonic relaxation 最速下降法
